Apart from fire impacts, trend data are not entirely consistent. It is estimated that the 2019–2020 fire season reduced the carrying capacity of 40% of grid cells by half and resulted in 10% mortality (Cameron et al. Combining these measures and uncertainty creates a likely population estimate of between 17,600 and 35,200 mature individuals, with a most likely figure (the midpoint) of 25,300. The density applied assumes an average density of 3.1 birds/km 2, that the 2019–2020 fire season reduced the carrying capacity of 40% of grid cells by half and resulted in 10% mortality (Cameron et al. (2021), the smallest being the number of 2x2 km squares for which there are records since 1990, the latter being an arbitrary value of nearly double this to account for incomplete survey effort of potentially suitable habitat. Population justification The estimate used here is the product of three predicted AOO measures (spanning 22,700-40,000 km 2) from Cameron et al. For these reasons the species is assessed as Vulnerable. Outside of a chicken shop you may struggle to recognise anything more than the bin chicken staring longingly at your chicken burger.Justification of Red List category Despite this species having a large range, reporting rates and the impacts of recent fires indicate rapid population declines in the last three generations, and this decline is likely to continue with climate change projections. You’re not a total Galah and you may know what to do to avoid a magpie swooping you, but heaven help us if you’re on a plane when a goose flies into the cockpit, knocking the pilot unconscious prompting the cabin steward to run in asking, “Is there an ornithologist on board?” Getting a bit cocky now, aren’t you? Sure you may know that a shrike-thrush is neither a shrike nor a thrush, but would you know the bird formerly known as Little Shrike-thrush has now been split into seven different species? Exactly where you’ll end up if you insist on dropping these ornithological tidbits at family gatherings. For not only are you smug in the knowledge that this is the correct spelling of a member of the crow family called the Red-billed Chough, which was mentioned by Shakespeare in King Lear, but that it is unrelated to the Australian White-winged Chough, which is in a completely different family. You must be pretty choughed with yourself. , 10:D - A bird of the dense rainforests west of Mackay, the Eungella Honeyeater wasn’t first officially described until 1983. , 9:B - The Buff-breasted Paradise-Kingfisher usually nests in a termite mound on the rainforest floor, creating a hole by repeatedly flying at the mound and bashing it with its bill. , 7:C - While the Giant Kingfisher of Africa is sometimes greater in length, there is no kingfisher in the world that outweighs a Laughing Kookaburra., 8:A - Contrary to what many Australians believe, the original Jabiru is a South American stork whose name derives from the Tupi-Guarani language of Brazil. Which was the most recent of these Australian birds to be ‘discovered’ and recognised by western science?ġ:C - Male Palm Cockatoos on Cape York drum their stick against a hollow tree in order to attract a mate., 2:A - Perhaps if it had a more pleasant-sounding name to begin with, this rare woodland bird wouldn’t be on the edge of extinction., 3:D - This dinosaur-like bird scurries through the dense undergrowth to feed its chicks in a domed nest hidden usually on the ground., 4:C - What’s that, Skip? The whipcrack call of an Eastern Whipbird is actually produced by a pair of whipbirds in what is known as antiphonal singing? Aww, gee!, 5:B - The plain looking but sweet-voiced Western Gerygone has three distinct populations, one in Western Australia, one in Central Australia and the other in the drier parts of Eastern Australia., 6:A - These tiny, poor-flying wrens were burnt out of 68% of their heathland habitat on Kangaroo Island. Which of these birds does not typically nest in a tree hollow? The word “Jabiru” is an indigenous name for a stork from which country? Which of these Australian birds are the largest member of their family worldwide?
Which bird had the greatest amount of its habitat burnt in the 2019/20 bushfires? Which of these western birds also naturally occurs in eastern Australia? What bird did Sonny from the 1960s TV series “Skippy the Bush Kangaroo” imitate in the opening credits by playing a gumleaf? What is the only Australian cuckoo to build its own nest? Which bird was known for much of the nineteenth century as the Warty-faced Honeyeater? Which Australian bird makes a drumstick to bang out a rhythm to attract a mate?
