2024 Great Southern BioBlitz – 20-23 September

Posted on 10 September, 2024 by Anna

Castlemaine Field Naturalists Club is again hosting the Great Southern Bioblitz for the Castlemaine region. GSB24 runs from September 20 to 23 2024 with citizen scientists from across the Southern Hemisphere photographing and audio recording as many living species as possible within their regions.

Get involved and help showcase all the amazing forms of wildlife living in our own Castlemaine region and help build the scientific databases that increase knowledge and understanding of our bushlands. These annual Bioblitz surveys collect vast amounts of data on species and distribution that would otherwise be unavailable.

To join the fun take photographs or make sound recordings of flora, fauna and fungi between 20-23 September. You have until 7 October 2024 to upload them to iNaturalist from your phone app or computer. iNaturalist is a global databank for observations of biodiversity made by scientists, naturalists and citizen scientists. Then skilled naturalists, scientists and other citizen scientists will help you identify as many of your observations as possible.  If you’re unsure on how to use iNaturalist, the Field Nats will be running a Beginners Guide to iNaturalist on Wednesday 11^th Sept at 7pm (bookings required at  https://www.trybooking.com/CUPWG )

There are a series of events hosted by Castlemaine Field Naturalists Club, as part of the Bioblitz. See below for details.

Friday 20th – Monday 23^rd September – make your observations and attend the following special events.  Observations must be from the Mt Alexander Shire or the eastern half of Hepburn Shire including Daylesford and Trentham.

Friday 20^th Sept from 7pm: Moth Night

Moths hold vital roles in ecosystem biodiversity. They are an important food source and great pollinators. The majority of species are nocturnal and most of these are attracted to light. Come along to watch these moths flying onto illuminated moth sheets and be amazed at the variation in sizes and colour of these beautiful creatures. A moth scientist will be on site to help with identification.

We will set up the lights and moth sheets at the southern end of the Castlemaine Botanical Gardens near the Walker St bridge (Opposite The Mill).

Sunday 22^nd Sept.  1:30-3:30pm, followed by afternoon tea. Bioblitz Afternoon in the Bush.  All Welcome

As part of Bioblitz 2024, we are offering the opportunity to spend a very special afternoon in the bush with four of our highly regarded local wildlife experts. Immerse yourself in the sights and sounds of the bush and record what you see and hear with photos or audio.

Bring your phone, camera, binoculars, magnifying glass and unbridled, childlike curiosity! And a cup for afternoon tea. If you wish, bring something for afternoon tea to share afterwards.

Meet at the Red White and Blue Picnic Area in Muckleford Forest – click here for directions.

Friday 20^th Sept to Monday 7^th October.  Load and Identify

During this time, load your observations made between 20^th and 23^rd Sept to the iNaturalist platform.  They will be automatically included in our GSB24 project.  https://inaturalist.ala.org.au/projects/great-southern-bioblitz-2024-castlemaine-region. You can also help identify the observations that others have made.

Want a challenge?  Can you make and load more observations than our very own “Babblerboy” who in 2023 recorded 799 observations of 256 species – no. 17 globally!

Bird of the Month: Australasian Grebe

Posted on 19 June, 2024 by Ivan

Welcome to Bird of the Month, a partnership between Connecting Country and BirdLife Castlemaine District. Each month we’re taking a close look at one special local bird species. We’re excited to join forces to deliver you a different bird each month, seasonally adjusted, and welcome suggestions from the community. We are blessed to have the brilliant Jane Rusden and Damian Kelly from BirdLife Castlemaine District writing about our next bird of the month, accompanied by Damian’s stunning photos.

Australasian Grebe (Tachybaptus novaehollandiae)

Australasian Grebes hold a special place in my heart, simply because they have such cute fluffy bums and can often be seen on dams. They are seemingly half fish, spending their lives on or under water. They nest on rafts and can spend long periods under the water foraging. On land they are quite ungainly and walk very awkwardly. And then there’s the chicks, the cutest striped balls of fluff riding on a parent’s back, tucked safely away in a bed of living feathers.

The Australasian Grebe is too cute for words.  Photo Damian Kelly

Appearance can vary quite a bit. In the breeding season, both males and females have a glossy-black head with a chestnut stripe on the face extending from behind the eye through to the base of the neck and a distinctive yellow patch below the eye. In contrast, the non-breeding plumage of both sexes is dark grey-brown above with silver-grey below and lacks the distinctive yellow patch. Juveniles are quite different again, with camouflage-type black stripes on grey plumage.

They are adaptable and can be found in varying habitats from small farm dams to larger bodies of water. Food includes fish, snails and aquatic arthropods usually collected by diving. Grebes are also known to eat their downy feathers and feed feathers to their young. Various reasons have been suggested for this behaviour ranging from aiding digestion to assisting the formation of pellets to help eject fish bones, but definitive reasons are yet to be determined.

Grebes are known to be quite mobile and will fly to new areas as water levels change. Flight is generally undertaken at night. They have also colonized New Zealand in recent times.

The Australasian grebe is common on freshwater lakes and rivers in greater Australia, New Zealand and on nearby Pacific islands. Photo: Damian Kelly

Nests are a floating mound of vegetation that is usually attached to a submerged branch or other fixed object. Over a season, two or three clutches of 3-5 eggs are laid. At times two females may lay in the same nest.  Young can swim from birth and are fed by both parents. However, if a second clutch is laid the young of the previous brood are driven away.

Bird of the Month: Brown Goshawk

Posted on 23 January, 2024 by Ivan

Welcome to Bird of the month, a partnership between Connecting Country and BirdLife Castlemaine District. Each month we’re taking a close look at one special local bird species. We’re excited to join forces to deliver you a different bird each month, seasonally adjusted, and welcome suggestions from the community. We are blessed to have the brilliant Jane Rusden and Damian Kelly from BirdLife Castlemaine District writing about our next bird of the month, accompanied by Janes’s stunning photos.

Brown Goshawk (Accipiter fasciatus)

Observed one morning when walking through the bush on my block, a Brown Goshawk pursued an Australian Owlet-nightjar in a fierce dog fight, flying at full speed down the gully, dodging trees by millimetres. The Brown Goshawk managed to catch the desperate Owlet-nightjar just before they saw the two humans, then they tumbled to the ground still locked together. the poor little Owlet Nightjar looked stunned and worse for wear, while the Brown Goshawk flew up into a tree, reluctant to loose it’s prey. The Owlet-nightjar at least got a bit of a breather, before both birds went their separate ways. I have no idea if the Owlet-nightjar survived the lethal body-puncturing talons of the Brown Goshawk, but the Goshawk certainly went hungry that morning.

The Brown Goshawk is one the Australia’s most widely distributed raptors and can be found across Australia and Tasmania as well as other islands, although it not as common in the very dry areas inland. It is a very versatile predator that uses a wide range of hunting techniques and can target a wide variety of prey. It will stalk grasshoppers on the ground, pursue small birds through the air and sit unobtrusively in cover, ready to glide down to catch prey on the ground. This prey ranges from insects to quail along with small rabbits, mice, lizards and snakes as well as yabbies and at times, carrion. Prey is usually 500g or less, but items such as young rabbits and reptiles up to 1kg have been known to be taken by female goshawks which are much larger than the male. Owlet-nightjars weigh 35-65g, putting them firmly in the small bird category of prey.

The Goshawk is also well known for lurking around chicken coops and aviaries looking for dinner opportunities, as well as soaring up high on the lookout for prey. It is known to be a reckless and persistent hunter, chasing birds through the undergrowth, exactly like the Goshawk chasing the Owlet-nightjar down the gully, and at times will chase prey into or under buildings. Young goshawks, in particular, have a reputation for being quite reckless at times when chasing prey, dashing through dense foliage and into chicken pens.

Although quite common and widespread in both bushland and urban areas it often goes unnoticed due to its cryptic behaviour, sitting very still in foliage and silently observing with intense yellow eyes.

The introduction and spread of the rabbit along with the opening of forests has probably led to an expansion of its range since European settlement.

Nests are built usually in the fork of a tree out of sticks and foliage. 1- 5 eggs are laid (usually 2-4) and both parents will incubate and feed the young. Adults tend to be fairly sedentary but young birds have been know to spread quite long distances in their first year, with some banding re-captures over 900km from a nest site.

Identification

The Brown Goshawk can be tricky to distinguish from the closely related Collared Sparrowhawk. Although the female Goshawk is quite a bit larger at 45-55cm in length, the female Sparrowhawk (35-38cm) is almost as large as the male Goshawk (38-45cm). Colouration and habitat tend to be similar and differentiating the two species can be hard in the field, especially when you only get a fleeting glimpse of these fast and cryptic birds.

In short, the best indicators to separate them are as follows:

Pollinator heroes of Central Victoria: Common Halfband Hoverfly

Posted on 30 November, 2023 by Ivan

With spring upon us, now is the perfect time to take a closer look at the smaller pollinator heroes of our region! There is plenty to see and hear across all habitats across central Victoria if you stop and pay attention to the little things. Throughout the warmer months the bees are buzzing, butterflies are fluttering, beetles are looking for mates and wasps are making nests. There is plenty to see and hear across all habitats in central Victoria if you stop and pay attention to the little things. These wonderful pollinating creatures are the heroes of the bush, grasslands, our gardens and waterways.

The Buzz project: promoting pollinators of central Victoria, is a Connecting Country project funded by the North Central Catchment Management Authority (NCCMA) through the 2022 Victorian Landcare grants, that aims to celebrate and expand community knowledge on the smaller heroes of our local ecosystems, the insect pollinators.  As part of this project, we have explored the lives of some of our most loved native pollinators from across the local region through a series of blogposts throughout November. This is the final blogpost in this series, with the hero of focus from the endearing hoverfly family.

Dr Mark Hall, local entomologist, has kindly shared his extensive knowledge on some of the local pollinator heroes that are so important to the health of our ecosystems. 

Common Halfband Hoverfly (Melangyna viridiceps)

Words by Dr. Mark Hall

Hmm, is this a bee? It certainly looks a bit like one with those bright yellow bands. And it is visiting lots of flowers. No, this is actually a fly trying to mimic a bee. Thankfully there are some tell-tale signs to tell the two apart. See those really big eyes, and the very short antennae? Unlike bees that have oval eyes on the sides of their head, fly eyes are typically much larger and rounder, sometimes taking up most of the head. And the antennae are shorter in flies, whereas bees have longer, segmented antennae. And that’s not where the differences end.

Flies are often more abundant in cooler climates, such as higher-up mountains, and can forage in colder weather (so can be more active than bees in early spring in this region). Whereas bees will often be more direct in their fight for flowers, hoverflies spend a lot of time flying above flowers, seemingly surveying for the perfect one before landing. Like bees, they feed almost exclusively on flowers (their larvae eat aphids) and are very good pollinators. They are fast flyers like bees, but they do lack the branched hairs that make bees exceptional pollen carriers.

The Common Halfband Hoverfly is a slim-bodied fly with reddish brown eyes, dark thorax and black and yellow banded abdomen. Photo by John Walter.

The Common Halfband Hoverfly can be found across most habitats in south-eastern Australia and in the southwest, including quite arid environments. They will feed on the nectar and pollen of many different types of plants and can also be confused with other hoverfly species, most typically the Yellow-shouldered hoverfly (Simosyrphus grandicornis), which is also common and abundant.

Why not take the opportunity to slow down this spring and take a look in your local bushland or garden and see what pollinator heroes you can find?

Pollinator heroes of Central Victoria: Imperial Jezebel

Posted on 21 November, 2023 by Ivan

It’s springtime and the flowers are blooming, the bees are buzzing, butterflies are fluttering, beetles are looking for mates and wasps are making nests. There is plenty to see and hear across all habitats across central Victoria if you stop and pay attention to the little things. These are the heroes of the bush, grasslands, our gardens and waterways.

The Buzz project: promoting pollinators of central Victoria, is a Connecting Country project funded by the North Central Catchment Management Authority (NCCMA) through the 2022 Victorian Landcare grants, that aims to celebrate and expand community knowledge on the smaller heroes of our local ecosystems, the insect pollinators.

The project has been running throughout 2023 and has included a presentation with local entomologist Dr Mark Hall covering ‘Native pollinators on your property: who, where and what they do?’ followed by a field trip that took a further look into ‘promoting native pollinators from property to landscape.’

During November, we will explore the lives of our most loved native pollinators from across the local region. Dr Mark Hall, local entomologist, has kindly shared his extensive knowledge on some of our local pollinator heroes that are so important to the health of our ecosystems. 

Imperial Jezebel (Delias harpalyce)

Words by Dr. Mark Hall

With Christmas approaching, you may hear the familiar tune of “I saw mommy kissing Santa Claus, underneath the mistletoe…”. And while that particular type of mistletoe is not native to Australia (and in fact is an environmental weed), there are a number of plants we call mistletoe in Australia that are native and have another species “kissing” underneath them at this time of year. The mistletoes in question are a group of semi-parasitic shrubs, often associated with Eucalypts – Amyema, Muellerina and Dendrophthoe species. The faunal species in question is the Imperial Jezebel butterfly (among others).

This spectacular butterfly species can be found across the south-east of Australia in all sorts of habitats where there are mature trees with mistletoe hanging and flowers to feed from. It is an early spring emerger and most active between August and November, where it mates and lays its eggs on the mistletoes, but can be active across all warmer months. The hairy black larvae (caterpillar) then feed on the mistletoe leaves, which not only help them grow, but also makes them taste pretty bad to predators – a win-win!

The large adult butterfly is almost entirely white (or greyish in some regions) on top of its wings, with some black edging and white spots on the outer wings. But it is the underside that is really captivating. In flight or when at rest with wings folded up, the black and grey wings, punctuated with bright red and yellow bands, are clearly visible. At this time you may also notice the hairy body and long clubbed antennae. The Imperial Jezebel is a great pollinator and certainly a hero of our gardens and bushland.

Wetland Revival Trust discovers new Eltham Copper Butterfly population in the Wimmera

Posted on 28 February, 2023 by Ivan

Connecting Country has partnered with local ecologist Elaine Bayes (Wetland Revival Trust) over many years to help monitor and conserve the critically endangered Eltham Copper Butterfly. We have delivered education programs and coordinated monitoring events in central Victoria, with Elaine tirelessly leading the campaign to improve land management practices and promote the survival of this iconic and fascinating species.

Elaine and her team at the Wetland Revival Trust recently reported some great news: they discovered the largest population of Eltham CopperButterfly and the largest area of habitat ever found! The new population is at Gerang Gerung, in the Wimmera region of northwest Victoria.

We congratulate Elaine and the team on their perseverance and recent exciting discovery!

The full media release is provided below, courtesy of the Wetland Revival Trust.

Wetland Revival Trust discovers National treasure in the Wimmera with the largest population of the Eltham Copper Butterfly found at Gerang Gerung

Wetland Revival Trust’s (WRT) long term butterfly project in northern Victoria discovered the largest population of the nationally endangered Eltham Copper Butterfly (ECB) (Paralucia pyrodiscus lucida) in the Wimmera, at two Gerang Gerung nature reserves.

Elaine Bayes, an ecologist from Wetland Revival Trust, a not-for-profit environmental charity, has been involved in the protection of this tiny butterfly since 2009.

Elaine started a search and find mission in 2019 in north central Victoria, where there are several ECB populations. The search spread to the Wimmera which may be the prime location for this species. Elaine said, ‘ECB numbers at the two very small known populations in the Wimmera were at much higher densities than in the north central where we had been searching.’

‘This year, our team searched 1,600 hectares of public land for the butterflies, 1,400 ha of which was in the Wimmera. And we were certainly rewarded for the effort, with around 500 ECB seen between the two Gerang Gerung reserves. To give perspective, in north central Victoria last year, we searched 1000 ha and found a total of 43 ECB peppered across a large area. To see 500 ECBs in one season is exceptional, and so far, this is the largest number of ECB and the largest area of ECB habitat ever found.’

This search was funded thanks to the Victorian Government Biodiversity On-ground Action Program (Icon Species Projects) which supports actions to protect nationally endangered species like ECB. ECB were first found in the Wimmera in 1988 at Salisbury Bushland Reserve and in a small area of Kiata Flora Reserve. In 2011, another tiny population (6 hectares) was found on a Wail roadside by local entomologist Fabian Douglas. In the intervening years, the Salisbury population became extinct, believed to be caused by sheep grazing out the butterfly’s food plants. The two remaining populations at Kiata and Wail are separated by a sea of agriculture, with nowhere for their young to disperse to.

There is no way for the populations to move around as environmental conditions change, and no corridors of native vegetation for the butterflies to move along so they can share DNA to make them more resilient. Also being small the sites are under threat from pests, weeds and roadworks.

Elaine believes that part of the reason ECB is rarely seen is that they require very specific conditions. As well as being dependent on one plant species to feed their larvae, the Sweet Bursaria (Bursaria spinosa), they require one specific ant species (Notoncus ectatommoides) to act as a bouncer for their larvae, scaring off predators that would otherwise feast on their juicy bodies. Their other very specific needs are that these delicate little butterflies are solar powered and only fly when it is 20-30 degrees with no wind or rain. The adults only emerge when there is abundant nectar around November and December usually peaking at Christmas and New Year (with a smaller emergence in March and April). Finding field staff to search for ECB at Christmas and New year is as rare a thing as finding the ECB themselves!

To find this elusive species you first find the one and only plant species it relies on, Sweet Bursaria (Bursaria spinosa) which is much easier to map as it is large, stays still and is present all year round! Previous searches have shown that ECB only occur where Sweet Bursaria plants are dense (more than 30 plants in a ¼ hectare). So, the first part of the plan is to search for and map dense Bursaria patches. The second part is to search those dense patches for ECB during their flying period.

Given the cool start to summer this year the number of days that ECB were flying before it became too hot for them was less than fourteen. WRT had ten field staff and several volunteers out searching the 1400 hectares. Ten very dedicated people who put this conservation work before summertime at the beach. The team searched areas including Gerang Gerung Mallee Dam, Gerang Gerung South Reserve. Glenlee NCR, Barrett NCR, Lierschs NCR, Coker Dam Wildlife Reserve and Lil Lil Dam and at a few locations in Castlemaine.

This work builds on WRT searches between 2019 and 2021 and a similar search in 2011, when large areas were mapped and collectively thirteen new populations around Central Victoria and at one at Wail were found. The new populations were very localised with the butterfly only occurring in 3-25 per cent of suitable habitat (where the ant and the host plant are present). This is reflected in this year’s survey where, out of 1400 ha, ECB was only found on 36 hectares.

The butterfly is listed as critically endangered under the Victorian Flora and Fauna Guarantee Act 1988 and as endangered under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999. This places considerable importance on managing the small number of known population sites and locating any potential new sites so they can be protected from threats.

The threats to this species in the Wimmera are numerous. Given the amount of historical land clearing in the Wimmera you can be confident that any quality remnant vegetation has a high likelihood of containing rare species, including insects, orchids and other plants and animals. Management and protection of these sites will bring benefits to multiple species as well as places of recreation and learning for future generations, impacts on local climate etc. Next year funding applications are in for weed and pest management, signage, translocations and more.

According to Elaine, it is undoubtable there will be ECB populations on private land where remnant vegetation occurs.

‘It is easy to check if you have any. First search your property or nearby bushland for dense patches Sweet Bursaria plants (easiest to see when flowering in December). Then look for the copper sparkle of flying adults in December on still days that are between 20-30 degrees. Tap each plant with a stick, which will cause them to fly and be more easily seen. Use the fact sheet and butterfly look alike sheet from the Eltham Copper Butterfly website (www.butterflies.net.au). Sightings can be reported on this site, the inaturalist app (www.inaturalist.org) or on the Butterfly Australia app (butterflies.org.au).’

Landholders can help protect this and other rare species by retaining and restoring native understorey plants on their properties.

Farewell Asha and welcome Hadley: a new Landcare Facilitator

Posted on 3 November, 2021 by Ivan

We recently said ‘goodbye’ to our much-loved Landcare Facilitator, colleague and friend, Asha Bannon. Asha has been an incredible asset to Connecting Country over the past (nearly) six years. She has provided inspiration and dedication to the role of Landcare Facilitator for the Mount Alexander region, and will be missed by the 30+ local groups who shared in her passion, vision and wisdom. Her commitment to the groups was a juggling act, with Asha often attending multiple events over a single weekend. Asha’s efforts have made a huge difference to the local landscape and the Landcare community.

We wish Asha the very best in her new role at North Central Catchment Management Authority, and are thrilled she will stay involved as a Connecting Country volunteer and supporter. Thanks also to all the Landcarers who have supported Asha during this time.

As one-star moves to another galaxy, another arrives. We have been very fortunate to recruit a new Landcare Facilitator – another local talent – Hadley Cole. We welcome Hadley with open arms and endless Zoom calls, and hope she enjoys the role and the team, as we regroup after a lengthy COVID-related ‘home office’ period.

Mysterious stockpiling frenzy hits the bush!

Posted on 5 August, 2021 by Ivan

We have all heard about the shortage of toilet paper across the nation, but it appears to have reached new levels in the bush blocks of Muckleford! We received a series of intriguing images from Connecting Country’s very own President and advocate, Brendan Sydes, showing some baffling theft of toilet paper courtesy of an unknown animal. We have a mystery to solve! Who took the roll of toilet paper from the outdoor toilet, to their home?  Let us play a game of ‘guess who stole the toilet paper’, revealing the clues in each image, and letting our audience guess the clever, resourceful and likely beautiful culprit.

A big thank you to Brendan for capturing this interesting mystery and sending us the photographs. Brendan noted that ‘The blue stuff in the box is a puppy chew toy which has also been commandeered by the occupant. The nest box has been there for about seven years and has been occupied by various native animals and bees before its present occupants’.

Let us know your thoughts and insights!

Rakali sighting at Expedition Pass Reservoir

Posted on 15 July, 2021 by Ivan

The gorgeous Rakali keeps a low profile in our community, with few sightings and some misconceptions about what is often called our ‘native otter’ or ‘Australian water-rat’. The Rakali is the largest native rodent and is a very attractive animal weighing up to 1.3 kilograms – as big as a medium-sized platypus. The Rakali’s ancestors are believed to have originally dispersed to Australia from New Guinea, where several closely related species are found today.

Connecting Country has been delighted to receive a sighting and video footage of a Rakali bathing in the glorious sunshine at our local Expedition Pass Reservoir. This is hugely impressive and important, as it validates a healthy waterway and restoration works for habitat and biodiversity. The footage was taken by local Chewton legends John Ellis and Marie Jones, who have been involved in many environmental and social projects in our region over the past decades. Marie said, “We stopped at Expedition Pass Reservoir to take a photo of a plant leaf to send to my daughter this morning and a rakali came along at the place where people tend to enter the water.  John luckily had his camera ready and this is the result. It made me feel as though we must be doing something right with the work we do – but then again perhaps it shows how versatile and adaptable these little creatures are!”

Please enjoy the footage below from John and Marie, uploaded to our Vimeo Channel. Further details about the Rakali and their distribution are also provided below, courtesy of the Australian Platypus Conservatory.

https://vimeo.com/573806062

Rakali distribution

The scientific name of the Australian water-rat is Hydromys chrysogaster, which translates as “golden-bellied water mouse”. Early European settlers sometimes referred to this animal as a beaver rat, though it’s actually much more like an otter than a beaver in both its appearance and behaviour. Since the early 1990s the water-rat has also been referred to as Rakali – the name used by the Ngarrindjeri Aboriginal people in the lower Murray River and Coorong region of South Australia.

Rakali occupy a wide variety of natural and man-made freshwater habitats, including swamps, ponds, lakes, rivers, creeks and irrigation channels. They also inhabit brackish estuaries and sheltered ocean beaches, and may populate ephemeral rivers and lakes in inland Australia when these fill with water after periods of unusually heavy rain. They tend to be most active in places where thick grass, low-growing shrubs, reed beds or large rocks provide plenty of cover on or near the banks. As shown below, water-rats are widely distributed on both the Australian mainland and Tasmania and also inhabit many offshore islands.

Size and appearance

Adult Rakali measure up to 35 centimetres in length from their nose to rump, with a slightly shorter tail. Adult males typically weigh 0.8 kilograms (up to 1.3 kg) and adult females typically weigh 0.6 kilograms (up to 1.0 kg). Animals living in different places often vary in colour. Most commonly, the head and back will be dark brown (with golden-yellow belly fur) or a lighter shade of brown, reddish-brown or grey (with fawn- to cream-coloured belly fur). However, apart from animals born near Shark Bay in Western Australia, virtually all individuals have a distinctive white tail tip.

Rakali fur is moulted twice a year, becoming thicker in winter. Like platypus fur, it consists of fine dense underfur covered by coarser guard hairs. However, Rakali fur is much less effective than platypus fur at keeping its owner warm – Rakali cannot efficiently maintain their body temperature in water below 20°C and therefore need to exit colder water periodically in order to warm up in a burrow or other sheltered site.

Whistling Kite surprises with phascogale catch

Posted on 30 June, 2021 by Ivan

(warning: graphic content of predator and prey)

Our region of central Victoria is home to numerous raptors, particularly in the vast plains to the north and west of Castlemaine, where species such as Whistling Kite, Black Kite, Brown Falcon, Kestrel and Black-shouldered Kite hunt the plains and farmland. Raptors are near the top of the avian food chain and feed on a variety of mice, rats, birds and native marsupials, as well as various roadkill species. They are excellent hunters, as well scavengers, and are often seen perched on dead trees and fences, eyeing off prey in the grasslands and pastures.

Local ecologist and author Damien Kelly has produced an excellent overview of raptors in our region. To view – click here

We were surprised by recently discovering a collection of images from a local resident, which showed a Whistling Kite grasping a captured Brush-Tailed Phascogale (Tuan). The photos show the brutal reality of the food chain and the incredible hunting skills of the Whistling kite. The photographs were taken by Helen McGeachin, and have been published here with her permission. Helen took the photographs a few years ago (June 2013) when she was working in her workshop in Elmtree Lane, Chewton VIC and looked up to see the kite (with poor little Tuan in hand ), which had landed on a nearby fence post.

The Whistling Kite is a medium-sized raptor (bird of prey) with a shaggy appearance. It has a light brown head and underparts, with pale streaks, and dark sandy-brown wings with paler undersides. The underwings have a characteristic pale ‘M’ shape when open. The head and body are relatively narrow and the tail is rounded. The wings are long and well-rounded, with a wingspan of 120 cm to 145 cm.

They are often seen near water or around farms, soaring in a lazy circling flight pattern. The distinctive call of the Whistling Kite is, unsurprisingly, a clear whistle, which begins by descending down the scale, followed by an up-scale staccato chatter, given by birds as they fly overhead or when perched. During the non-breeding season, they mainly eat carrion, but during the breeding season, they take live prey, especially rabbits and hares, as well as fish, reptiles, birds, small mammals and invertebrates. They sometimes attend fires to catch fleeing prey, and they may steal food from other birds of prey.

New surveys for Eltham Copper Butterfly habitat in Chewton

Posted on 22 April, 2021 by Ivan

The Eltham Copper Butterfly (ECB) is one of our most interesting and treasured local threatened species. We are fortunate to have the largest population in the world right here in the Mount Alexander region of central Victoria. In the past few years, this special little butterfly has attracted some much-needed attention, with several small but important projects active in our region.

Passionate local butterfly gurus, Elaine Bayes and Karl Just, have obtained new funding to assess additional local sites for habitat suitable for Eltham Copper Butterfly during 2021-22. This includes the bushland around Castlemaine and Chewton.

The initial surveys will involve habitat assessment of the Chewton Bushlands for Sweet Bursaria (Bursaria spinosa), a plant vital to the Eltham Copper Butterfly’s life cycle. A team of volunteers will map the density of this beautiful flowering shrub. These maps will be used to plan surveys for the butterflies when they become active, in the warmer days of early summer days. The relationship between the density of Sweet Bursaria, and the presence of the Eltham Copper Butterfly has been identified in previous surveys in 2019 and 2020, around Kalimna Park in Castlemaine.

Stay tuned for further information about the Sweet Bursaria and Eltham Copper Butterfly surveys, which bring a real possibility of discovering new records for this threatened species. We acknowledge the commitment of the Eltham Copper Butterfly volunteers, and Elaine and Karl, who are committing much of their time to help protect and improve the habitat for this fascinating species.

In 2019-20, Connecting Country delivered a popular community education workshop, and worked with ecologists Elaine and Karl to promote and coordinate four community monitoring sessions for Eltham Copper Butterfly around Castlemaine, when the adult butterflies were out and about. These events attracted many people keen to learn more about the life cycle of this butterfly and to participate in butterfly monitoring within local butterfly habitat. The aim was to support interested community members to learn how to monitor with expert guidance, providing skills for them to become citizen scientists, conduct more monitoring and (potentially) discover new populations.

Ecology and habitat

The Eltham Copper Butterfly is a small attractive butterfly with bright copper colouring on the tops of its wings. It is endemic to Victoria, where it mostly lives in dry open woodlands. The Castlemaine-Bendigo population covers the largest area (>100 ha but full extent unconfirmed), followed by Kiata (90 ha) and Eltham-Greensborough (8 ha). The Eltham Copper Butterfly is only ever found in areas where Notoncus ant colonies are present, confirming they have a truly symbiotic relationship.

Adult Eltham Copper Butterflies lay their eggs at the base of Sweet Bursaria plants. The larvae hatch and make their way to the ant nest, where the caterpillars are guarded by the ants, which lead them to and from the ant colony to browse on the Sweet Bursaria leaves. In return, the ants feed on sugar secretions which are exuded from the caterpillars’ bodies.

Larvae pupate in or near the ant nest, with adults emerging from October to March each year, peaking from November to January. The adults feed on nectar of Sweet Bursaria flowers, and flowers of other plants such as Hakea species.

Bird monitoring 2020 results are in!

Posted on 4 March, 2021 by Jess

Connecting Country’s long-term bird monitoring program was established to investigate the relationship between habitat restoration and woodland bird populations across the Mount Alexander region in central Victoria. In 2020 sites were monitored by our team of tenacious volunteers, who managed to survey most of our sites, despite challenges associated with COVID-19 and lockdowns. The 2020 monitoring season was supported by the Australian Government’s Communities Environment Program. This was the second time our monitoring was 100% completed by volunteers.

Operation Hollows targets illegal firewood collection

Posted on 27 August, 2020 by Frances

Dead trees and fallen logs play an essential role in our local Box-Ironbark forest ecosystems. They provide food and shelter for countless living organisms from fungi and plants to the invertebrates that sustain larger animals such as woodland birds and Brush-tailed Phascogales. Many of our local birds, reptiles and small marsupials also rely on tree hollows for nesting and shelter.

 When people collect firewood from our native forests, and remove standing dead trees and woody debris on the ground, they can contribute to a serious loss of biodiversity and affect the long-term viability of wildlife habitat. Therefore firewood collection requires careful management. While many of us rely on firewood to keep us warm over winter, we can make sure our firewood is from a sustainable source. The Victorian Department of Environment, Land, Water and Planning (DELWP) and Parks Victoria have launched a statewide operation to address the destruction of wildlife habitat caused by illegal firewood collection in Victoria’s forests, parks and reserves. Here are some details from DELWP.

Operation Hollows is targeting the unlawful removal of commercial quantities of firewood from public land, and suppliers of illegal firewood.

Uncontrolled firewood collection can lead to the loss of important habitat such as hollow logs and dead trees. Habitat loss has a serious impact on iconic native species that rely on our forests to survive, such as the Powerful Owl, South-eastern Red-tailed Black Cockatoo, Greater Glider, Pygmy Possum and many others.

Treasure-hunting in the Goldfields

Posted on 20 August, 2020 by Asha

Yam-daisy (Microseris lanceolata) by Robert Macrae

We’re delighted to present a very special guest blogger: Asha Bannon. Asha will be known to many from her role as Landcare Facilitator for the Mount Alexander Region with Connecting Country. She is currently on extended leave, but took out time to prepare this for us.

What is special to you about the land around us? We have many treasures in our local bushland, often hiding in plain sight.

Next time you go for a walk, focus on tuning in to something new around you. I know I am usually on the lookout for birds, searching for signs of movement and bird calls, so it takes a shift in awareness for me to stop and take a closer look at the tiny plants and fungi near my feet. Perhaps you could take a magnifying glass out to look at mosses and insects, or take a few moments to close your eyes and purely listen to what’s around you. In these times when we need to shelter in place for a while, there are always new adventures to be had by discovering the different dimensions all around us.

The name of our bioregion, ‘Goldfields’, comes from the gold-mining in our history that drastically changed our landscapes. But it is important to remember that we also have an abundance of special plants, animals, and fungi which we should value like treasure, many of which share that golden colour. Trace Balla captured this sentiment in her book, ‘Landing with wings’ (picture shared here with permission).

Page from ‘Landing with wings’ by Trace Balla (shared here with permission)

Examples include common species, such as Golden Wattle (Acacia pycnantha) which is flowering in abundance right now, as well as threatened and rare species like Murnong (Microseris lanceolata) and Eltham Copper Butterfly (Paralucia pyrodiscus lucida). And the list goes on!

Tell us in the comments some of your favourite golden plants, animals, fungi, etc., and have a chat about them with your friends too to share the love for these treasures.

We have put together a simple worksheet with some easy-to-spot golden treasures to kick start your own checklist. Click here to download a copy, or you can make your own, either with golden treasures or another dimension of nature you’d like to explore. If you can’t get out into nature at the moment, click here to explore some Natural Newstead blog posts as the next best thing.

Getting that frog call checked by experts

Posted on 16 July, 2020 by Frances

All creatures great and small are celebrating the return of water in the landscape this autumn and winter 2020, with some healthy rainfall recorded across the Mount Alexander region in recent months. You may have heard an abundance of frog calls. Even here in the Connecting Country office at the Hub in central Castlemaine VIC, we’ve heard frogs in the adjoining community garden. One of the blessings of living in a healthy landscape is hearing the chorus of frog banter and the sounds of abundance.

We received a timely reminder from our local frog expert Elaine Bayes, of the importance of using the brilliant FrogID App for assisting with the identification of tricky frog calls of our region. FrogID is Australia’s first national citizen science frog identification initiative – a project led by the Australian Museum in partnership with Australia’s leading natural history museums and IBM. Anyone can use the App to create a profile, record frog calls and match your calls to the frog calls on the app, then upload your records to the Australian Museum frog experts for species verification.

One of the reasons to use the FrogID app is to ensure that all frog records are verified prior to entering records into the Atlas of Living Australia (ALA), the largest database of flora and fauna records in Australia. Records entered directly in the ALA are not verified, and it was recently discovered that there were some incorrect records of frog species entered in the Mount Alexander region. The ALA contains a number of sightings in our area of Striped Marsh Frog, which was previously rare in this region. However, upon closer assessment by frog experts, they suspect the frog recordings are actually the Spotted Marsh Frog (Limnodynastes tasmaniensis), not the Striped Marsh Frog (Limndoynastes peroni). The two calls are similar and easily confused.

This is an important case study of how incorrect identification can potentially affect distribution datasets. This is not the case with the Victorian Biodiversity Atlas, as every record submitted by users is verified for possible errors or mistaken identification.

The frog recordings submitted via the FrogID app are often verified in less than 24 hours, and it is a great resource to improve your skills and learn a lot more about frogs along the journey.

In just one year, FrogID has generated the equivalent of 13% of all frog records collected in Australia over the last 240 years – an amazing effort! The submitted recordings have resulted in over 66,000 validated calls and detected 175 of Australia’s 240 known native frogs.

The data has provided information about:

• Impacts of climate change and pollution on Australia’s frogs including the first evidence of the decline in Sydney of the Australian Green Tree Frog.
• Spread of the invasive Cane Toad.
• Breeding populations of 28 globally threatened and 13 nationally threatened frog species.

Victorian Biodiversity Atlas: its purpose and significance – 10 July 2020

Posted on 7 July, 2020 by Jess

Castlemaine Field Naturalists Club (CFNC) are hosting an online event the evening of Friday 10 July 2020 titled ‘The Victorian Biodiversity Atlas: its purpose and significance’, featuring Elizabeth Newton, who has worked for the Department of Environment, Land, Water and Planning and currently works with Trust for Nature. This free online webinar is open to the community to learn more about this important topic.

At Connecting Country, we encourage the community to submit fauna and flora records to the Victorian Biodiversity Atlas. You can read more about the Victorian Biodiversity Atlas (click here) and about our amazing volunteers who have submitted hundreds of records to this important database (click here). Learning more about the Victorian Biodiversity Atlas, and uploading any of your own fauna and flora records is a great way to contribute to nature conservation, especially if you have some extra time at home during the COVID-19 pandemic.

CFNC meetings are usually held on the second Friday of each month (February to December) starting at 7.30 pm. Due to government requirements, the CNFC committee has decided to suspend all club face-to-face activities until further notice.

Details of this event, including how to register, are provided on the CNFC website (click here)

The Victorian Biodiversity Atlas (VBA) is a foundation dataset that feeds into biodiversity tools used in the government’s everyday environmental decision making. Approvals and permits, funding decisions, and burn planning all rely on biodiversity observations submitted to the VBA.

This presentation will cover what the VBA is, contributing your data, and how your own flora and fauna records can make a difference.

It will also explore why the Department of Environment, Land and Water (DELWP) uses the VBA, and how it differs and interacts with other biodiversity databases such as Atlas of Living Australia, iNaturalist, and Birdata.

If you wish to attend this webinar, please email Peter Turner at munrodsl@iinet.net.au to receive details on how to attend.

If you previously registered for CFNC’s May webinar you will receive an email with details on how to register for the July session.

Bird of the month: Eastern Spinebill

Posted on 23 April, 2020 by Ivan

Welcome to our third Bird of the month, a partnership between Connecting Country and BirdLife Castlemaine District. Each month we’re taking a close look at one special local bird species. We’re excited to be joining forces to deliver you a different bird each month, seasonally adjusted, and welcome any suggestions from the community. We are lucky enough to have the talented and charismatic Jane Rusden from BirdLife Castlemaine District writing about our next bird of the month, with assistance from the brilliant Damian Kelly. You may be familiar with the third bird off the ranks.

Eastern Spinebill (Acanthorhynchus tenuirostris)

This month has seen the return of the Eastern Spinebill to Central Victoria, as they leave higher elevations for the winter. I’ve noticed them feeding on Rock Correa around my house and Geoff Park wrote about their return on his blog, of course, accompanied by his stunning photos. This is a species that has adapted to gardens and will utilise non-native species of flowering plants, such as Salvia, in their search for nectar. Did I mention Correa, they LOVE Correa.

The Eastern Spinebill, though a Honeyeater, is arguably our local answer to the humming bird, as they have a habit of hovering whilst using their long curved bills to probe flowers. This ability means they can feed on nectar plants too delicate for birds to actually land on. In addition, they eat plants and a large assortment of insects. If you’ve read Tim Lowe’s book ‘Where Song Began’, you’ll know birds use nectar for energy, but its’ relatively low nutrient levels mean birds look to insects for minerals and other nutrients.

So here’s an interesting thing: through our research on this gorgeous little honeyeater, Damian Kelly and I noticed an anomaly that we can’t get to the bottom of. The guide books say that during the summer Eastern Spinebills retreat from low elevations to higher elevations and can be found in places like the High Country. However, around mid elevations such as Cottles Bridge (north east of Melbourne VIC), they can be found all year round. Young birds are known to travel larger distances and usually appear locally before the mature adults do. However, an extensive long-term study across most of their range (from South Australia, through Victoria to New South Wales) from 1984 to 1999 involved mist netting and banding 39,572 Eastern Spinebills with a re-capture of 3,602 birds. The study discovered that 99% of re-captured birds were less than 10 km from their original banding location. In short, they had moved very little distance at all, but the same cannot be said for our local birds. It would be fascinating to know what’s going on here.

Perhaps this is a highly adaptable bird? It will nest under verandahs and utilise non-native food sources such as fuschia, move if it has to, or not if it doesn’t. For a small bird they are reasonably long lived. In the  study mentioned above, one individual was banded as an adult, then caught six more times during the study period, which means it was an adult for at least 13 years and 2 months.

I suspect there’s much going on with the Eastern Spinebill, much more than feeding on their favourite Correa and being chased across the garden by other honeyeaters, which is how we often see them. Anyone up for a PhD on Eastern Spinebills …?

Take a guess….how many Eltham Copper Butterflies did we see last summer?

Posted on 2 April, 2020 by Ivan

The Eltham Copper Butterfly (ECB) is one of our most treasured and interesting threatened species, and we are fortunate enough to have the largest population in the world right here in the Mount Alexander region of central Victoria. In the past 12 months, the special little butterfly has attracted much-needed attention, attracting funding for three separate projects in our region.

Connecting Country obtained funding from the Mount Alexander Shire Council to increase community awareness and education regarding the butterfly, and to support citizen science monitoring in key locations to learn more about the local populations. We worked closely with local ecologists Elaine Bayes and Karl Just, who with support from Wettenhall Environment Trust continued their vital work on mapping local Eltham Copper Butterfly habitat and distribution. We also joined in the excellent Butterfly Celebration Day held in Castlemaine Botanical Gardens in November 2019. Our hope is that all Castlemaine residents now know about this amazing threatened species living on their doorstep!

Connecting Country delivered a popular community education workshop, and worked with ecologists Elaine and Karl to promote and coordinate four community monitoring sessions for Eltham Copper Butterfly around Castlemaine VIC over November 2019 to January 2020, when the adult butterflies were out and about (for details – click here). These events attracted excellent numbers of people keen to learn more about the life cycle of this butterfly and to participate in butterfly monitoring within local butterfly habitat. The aim was to support interested community members to learn how to monitor with expert guidance, providing skills for them to become citizen scientists, conduct more monitoring and (potentially) discover new populations.

Well, the results are in, the numbers crunched and the maps produced! We now have some great insight our local Eltham Copper Butterfly populations, including previously unexplored areas of potential butterfly habitat. In total 113 individual Eltham Copper Butterflies were observed in the prime flying period between 15 November 2019 and the 3 January 2020.

Monitoring results

Our monitoring experts, Elaine Bayes and Karl Just, provided the following summary of the results, accompanied by a very detailed and useful map of the areas they visited:

• The monitoring team searched, ranked and mapped all of Kalimna Park (170 hectares) for butterfly habitat in November 2019. Time spent to carry out rapid assessment was 48 hours.
• This work determined that out of 170 ha of Kalimna Park, 73.25 ha was classified as prime potential Eltham Copper Butterfly habitat (i.e., medium or high quality Sweet Bursaria habitat).
• Using Eltham Copper Butterfly habitat mapping, the team searched areas that were determined to have good butterfly habitat potential. Using this method the group located five new Eltham Copper Butterfly sub-populations and extended the area of known Eltham Copper Butterfly occupancy from 3 ha to 8 ha.
• In total 113 individual Eltham Copper Butterflies were observed in the prime flying period between 15 November 2019 and the 3 January 2020 (some of which may have been double-counted from resurveying same area).
• The total survey effort or time spent searching for butterflies in this period was 187 hours.
