Australian Bird Index launched

Posted on 17 July, 2015 by Tanya Loos

On Wednesday (15 July 2015), BirdLife Australia launched the Australian Bird Index. This ground-breaking research measures the health of Australia’s terrestrial bird populations. For the first time, vast quantities of data collected by volunteers and researchers have been analyzed to produce indices that help track Australia’s current state of biodiversity.

Just as the Consumer Price Index is a useful tool to evaluate the nation’s economy, The Australian Bird Index is a tool to quantify the overall health of the environment – using birds as the barometer.

The Bird Index has come about thanks to 15 years of citizen science data collection: comprising 14 million records and 900,000 surveys from across Australia – including many from the Mount Alexander region.

Now that Connecting Country is an affiliated organization with BirdLife Australia, both the data we collect for our long term monitoring program, and the data you submit, will be shared with BirdLife to assist in this important work.

So how are we faring? In order to make sense of the data, the Australian Bird Index breaks Australia up into nine regions: for example, the Mount Alexander Shire occurs entirely within the South-east Mainland region. In the South-east Mainland, dry woodland and forest dependent parrots are showing distinct downward trends over the last 13 years. These species include Purple-crowned, Musk and Little Lorikeets, Crimson Rosella and Yellow-tailed Black-cockatoo.

But we see Crimson Rosellas all the time, I hear you say – this is the tricky thing about analyzing the data over a large area – in some areas the rosellas may actually be steady or even increasing, whereas across other areas, rosellas are dropping out of the picture entirely. As such, BirdLife researchers plan to carry out further research for the comprehensive State of Australia’s Birds report planned for early release in 2016.

The Australian Bird Index can tell us that the Purple-crowned Lorikeet has declined markedly, but not why this beautiful little bird has been reported as declining. Again – further research is required to tease out some answers. My guess is that the changing weather patterns are playing havoc with the flowering of the eucalypts that these tiny blossom nomads rely upon.

Geoff Park has recently posted some stunning photos of the Purple-crowned Lorikeet (click here) and it is great to hear that readers of his blog have reported seeing this species in good numbers.
