Gray Currawong Strepera versicolor

Large, crow-sized bird, gray or black, with large black bill and yellow eye. In flight, white undertail, tail tip, and primary bases distinctive; some subspecies of Pied Currawong very similar, but Gray has narrow pale trailing edge to wing in all plumages. Black Currawong has thicker bill and dark undertail. Loud ringing, clinking song, reminiscent of some lyrebird sounds.
