for scraps where the opportunity arises. Large noisy flocks can be seen feeding in trees and it will also readily feed on the ground especially where grain and other seeds have been spilt or left unprotected on the surface of a field.
Call
The voice is quite remarkable and is rather un-crow like, with strange liquid bubbling notes and high ringing sounds produced in various combinations. It also produces a thin screeched ''"aaaaauh"'' that rises in inflection.
Breeding
The nest is built in tall trees, though little further information about breeding is recorded as yet.
