101 bird species spotted at Mornington-Marion Downs

13 Dec. 2022
AWC

AWC Field Guide Steven Spragg recently traversed across Mornington-Marion Downs Wildlife Sanctuary and identified 101 unique bird species – in one day!

The record for the most species sighted in Australia in one year (known as a Big Year) is 770 by John Weigel. Of course, a Big Year gets harder over time as a birder’s number of unidentified species depletes. Still, 101 species across one area, in one day, is no small feat.

Steven started his day at 4:46 am and finished nearly 14 hours later. In that time, he travelled 193 kilometres and spotted 1,936 birds. His findings show the epic diversity of species present around the birding mecca that is Mornington.

Have a gander at his list:

70 Gouldian Finch

AWC protects one of the largest remaining populations of the endangered Gouldian Finch at Mornington-Marion Downs, and smaller populations at Charnley River, Wongalara, Pungalina and possibly Brooklyn.

The primary threat to the survival of the Gouldian Finch is altered fire regimes – especially an increase in extensive, hot wildfires in the late dry season. Wildfires reduce the availability of seed at key times during the year and limit the availability of tree hollows for nesting. Until recently, people often travelled thousands of kilometres to catch a glimpse of a Gouldian Finch. Now, thanks to both heavy rainfall and active backburning to minimise wildfires at Mornington-Marion Downs, Steven only had to drive for five minutes to see 70 members of this species bathing and foraging in all their glory!

The Purple-crowned Fairywren’s coronatus subspecies is a staple along Mornington’s riverbeds but found almost nowhere else in the world. This Endangered subspecies’ range is limited to a small pocket of Western Australia and the Northern Territory, as it has adapted to live only along the banks of Northern Australia’s waterways. Much of its riparian habitat – particularly the Pandanus aquaticus vegetation that it nests in – has been decimated by feral herbivores and wildfire, causing significant declines in the Purple-crowned Fairywren population.

For close to two decades, Monash University researchers and AWC scientists have closely monitored an entire population of Purple-crowned Fairy-wrens at Mornington. Until 2018, they bucked the trend of decline the species was seeing elsewhere across Australia, with the number of breeding pairs increasing until the population had doubled in size! Then the vicious pairing of drought and wildfire in 2018 and 19 caused severe habitat damage, and their numbers saw a 41% decline. Both their flourishing numbers before habitat damage and extreme decline afterwards demonstrate the essentiality of habitat regeneration and maintenance in the survival of the species.

Despite its population decline, the Purple-crowned Fairywren population at Mornington has the highest density in its range, and so its little amethyst crown is a rare but wonderful treat for birders like Steven.

1 Barking Owl

This mid-sized, hawk-owl has very distinctive vocalisations – a gruff ‘woof-woof’ or ‘wuk-wuk’ that sounds remarkably like a dog’s bark, and a much rarer, wavering scream, resembling a high-pitched ‘help!’ Luckily for Steven, it often becomes active before dark, so he was able to tick his 101 species off without having to stay up all night getting spooked by its vocal tricks.

With his wonderful bird knowledge, you’d be hard-pressed to find a field guide savvier than Steven.
