Yellow, forwarded-curving crest
Yellow undertail and underwing
These birds are impossible to miss with their extremely loud screeching. They seem to be rather plentiful, often congregating in large flocks. I have seen them everywhere in Tasmania, both feeding on the ground and in trees. Apparently they like walnuts, or at least that was what one gentleman told me as he angrily shooed a very large number of them out of his yard. It's hard to imagine such beautiful birds being considered pest.
