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.

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.

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.

Thrilled to find this post. We have been fortunate to have grebes breed on our dam every year and love watching their antics. They rule the roost and have no qualms intimidating other water birds three times their size. Interesting to read about offspring from the 1st brood being driven away as that is what we saw happen a few years back. There was only one chick in the 1st brood and it had not learnt to dive for its food before being driven away by its parents. I was unable to find appropriate food for it and sadly it died of starvation. If anyone has information re what food can be provided / substituted I would be really interested as I don’t want to see such a distressing event like that happen again.
Yesterday was a black day when a hawk flew in and decimated the nest stealing all the eggs. The parents seemed pretty shell shocked and I can only hope they recover soon and set about laying more eggs preferably not in the same nest which the hawk regularly checks out from above.
Lovely to share news of our favourite diving duck.
Thank you. Beautifully described!
