Common Name- Forest Red-tailed Black-Cockatoo
Location- Kensington, WA
Post Production- Nikon ViewNX-i for viewing and selecting files; Adobe Photoshop Camera Raw/CC 2020 for resizing and cropping to 118% followed by conversion to Tif, selective sharpening and general post-processing incl. some halo removal; Topaz Pro plug-in DeNoise was used for notable blanket sharpening and moderate noise control. ‘Australian Bird Guide 2019’ was used for species distribution confirmation, supplementary data and colour checks; significantly, Johnstone & Kirkby ‘s (1999) study of ‘Food and feeding behaviour at Bungendore Park and Jarrahdale’ was also consulted.
Equipment & Technique:
Nikon D850 with GPS
Nikkor AF-S 500mm f4G ED VR
Technique: Camera rig support: Gitzo GT3543XLS Tripod, Dietmar Nill gimbal tripod head; standing tall under tree
Exposure Mode: MANUAL 1/2000 sec at f5.6 (maintaining an underexposure of ½ a stop); ISO-800. Metering Mode: MATRIX; Focus Mode: AF-C High & AF Area Mode: SINGLE
Notes- Image specific (23.02.21BiL_BOZ9803):
Depicted subspecies is the Forest Red-tailed Black-Cockatoo, Calyptorhynchus banksii naso.
I went to a small patch of bushland in Kensington, WA that holds many Jarrah trees, some Banksias and a few Marri Eucalypts. In particular the Jarrah Eucalypts were awash with feeding and resting Forest Red-tailed Black-Cockatoos. The birds numbered in their hundreds, and it had many begging youngsters were amongst them, these being fed by their mothers in the crown of the Jarrah trees. Marri and Jarrah Eucalypts mature patchily, so you never quite know when these majestic black-cockatoos will be visiting; the nuts of these trees have to be just right, before the birds will start to forage in them. However, just about this time of the year, the Western Australian black-cockatoos between them might begin to have exhausted fruiting Marri gum-nuts and change to Jarrah, which are fruiting later in the year. When a tree or a patch of trees are exhausted of their nuts, the birds will move on to another patch to forage in. Late in the afternoon, in warm sunlight, this image shows a male Forest Red-tailed Black-Cockatoo about to land, wings and tail fully spread out, the feet start coming forward to grab his perch.
GENERAL:
The south-western subspecies of Calyptorhynchus banksii is called the Forest Red-tailed Black-Cockatoo (C.b. naso). It occurs west of a line from Albany via Williams to Gingin. A canopy feeder, it inhabits the more humid, wooded areas. Common in the hilly forests around Perth, it is increasingly seen in the southern suburbs, where it feeds in remnant, seeding Marri trees. Notably, during August and September small flocks gather to feast on the drupes of the introduced Cape Lilac. A bird of the eucalypt forests, this subspecies feeds mainly on the patchily seeding Marri but Jarrah, Karri, Blackbutt, Snottygobble and casuarinas are also on the menu. The Forest Red-tail is not nomadic but undertakes some seasonal movements, if only to the extent of following seeding eucalypts. Alas, this subspecies is declining due in part to the slump of especially marri trees and competition for large nesting holes by the European Honey Bee. Kensington (GPS), WA. Status (Museum of WA 2021): Vulnerable
