They are also famous for tearing into the bark and branches of various trees, often dropping branches or snapping small saplings. For example, they take the woody fruit of Eucalyptus, Hakea, Banksia and a variety of introduced trees, including plantation pine trees. They feed in a wide variety of trees and may be found in woodland, parks, coastal heath or forest. In flight their long-tails, dark colour, and loud calls are distinctive. Yellow-tailed Black-Cockatoos may be seen flying in small or large flocks. Where to look for Yellow-tailed Black-Cockatoos Juveniles have colouration like female, but are best recognised by their continual, rasping begging calls.Adult male has red skin surrounding eye.Yellow cheek patch, larger and brighter in adult female than in the male.Pale yellow tail panels, variously mottled with black in both males and females.Large, slender bird with long tail and long wings.Some features to look for in recognising Yellow-tailed Black-Cockatoos the scattering of torn Allocasuarina fruit on the forest floor is quite diagnostic.

Small groups will sit quietly, chewing on the fruit, sometimes remaining in the same tree for hours. Glossy Blacks feed almost exclusively on Allocasuarina fruit (often called 'she-oak cones'). Soft, wavering call in flight - again, very different to the Yellow-tailed black call.
