PSITTACIFORMES: Cacatuidae
Calyptorhynchus latirostris
Male Carnaby's Black-Cockatoo.
While driving along the highway between Perth and Albany I came across a small flock of Carnaby's Black-Cockatoos feeding on gum-nuts on the ground metres from the road.
No doubt the birds had cut the gum-nuts from high in the tree before coming down to feed.
