“A juvenile from the second group made a beeline to the female in the first group and attempted to steal the gumnut she was eating.
All of a sudden another family group flew in, calling to announce their arrival,” Erika says. “I was watching a family group of cockatoos feeding in a marri, happily chomping away on the large gumnuts. Erika’s favourite is her ‘Nut Theft’ story. Over her studies, Erika has seen some of their complex social behaviours play out. A widespread species whose conservation management is hampered by a lack of genetic data is the red-tailed black-cockatoo (Calyptorhynchus banksii), one of Australia’s most iconic bird species. “Growing up near Canberra we would have yellow-tails visit our pine trees a few times a year and I’d run outside as soon as I heard them coming,” she says.Įrika now lives in Perth where much of her studies have focused on the forest red-tailed black cockatoo species ( Calyptorhynchus banksii naso ) in south-western WA, many of which have taken up residency in metropolitan areas. Forest Red-tailed Black-Cockatoos use their wide bill to extract seeds as Carnaby’s Black-Cockatoo do, but their wider bills leave long, flat marks on Marri fruit.

Forest Red-tailed Black-Cockatoos mainly eat seeds from the nuts of Marri and Jarrah trees but are known to also eat nectar, flowers and sometimes insects and larvae. Threats to the speciesĬlearing of forest, fires, climate change, vehicle strikes, feral European honey bees which take over nesting hollows and in the past large numbers shot by orchardists. Forages at all levels from canopy to ground. Also nectar, buds and flowers and strips the bark from dead trees in search of beetle larvae.
Feeds on seeds of eucalypts, Banksia, Hakea and fruiting apples and pears. Southern eucalypt forests of mainly Jarrah, Marri and Karri. Occurs in south-western humid and subhumid zones, north to Gidgegannup, east to Clackline, Wandering, Quindanning, the Perup River, Lake Muir and King River, and west to eastern strip of Swan Coastal Plain including West Midland, Gosnells, Byford, North Dandalup, Yarloop, Wokalup and Bunbury also the Stirling and Porongurup Ranges and along the south coast to Waychinicup National Park. Breeding call a repeated low "arr" followed by a high-pitched whistle. The male makes a longer “kurweeeurr” often given as a duet. The female’s contact call is a short "whicher whicher" or "bunyip bunyip" flock call.
#BLACK RED TAILED COCKATOO SKIN#
Like the male, but differs in having the ear coverts a brighter yellowish white bill greyish with dark tip and eye skin grey. Mostly brownish black, the feathers edged with dusky white giving a scalloped appearance ear coverts dusky white white band towards tip of tail, broken in middle bill black bare skin around eye pink. Upper bill narrower and longer than Carnaby's Cockatoo.
Eggs laid in August - December clutch 1–2 (only one young reared) and only the female incubates and broods the chick. Nesting in hollows of Karri, Marri and Wandoo trees. It has declined in the last 50 years, its low rate of reproduction (0.6 chick per year) precluding it from replacing the large numbers shot by orchardists. In the last 10 years (since 2016), there has been a dramatic decline in numbers recorded at traditional roosts sites. Mainly in flocks (up to 300 and occasionally larger aggregations of up to 1200 at roosts). It is scarce to moderately common (most numerous in deep south-west). "Endangered: under Federal Environment Protection and Biodiversity Conservation Act". "Listed Endangered: Schedule 1 - Western Australian Wildlife Conservation Act".
