Yellow-tailed Black Cockatoo: Wings and Tail
Yellow-tailed Black Cockatoo > Calyptorhynchus lathami
These birds are somewhat nomadic, following the food. They are partial to pinecones, and flocks will strip a stand of trees quite quickly. The technique is to nip off a green cone and then spend twenty minutes enjoying the seeds. They don't eat the "feather" of the seed and like little snowflakes they fall in showers from the tree.
The bird on the bottom righthand side shows the typical one legged feeding pose.
They also are easily able to extract borers from various tree species.
This small flock have turned up after about three years, and reports coming in seem to suggest that they are currently busy at many spots around Melbourne.
