This study is the result of a 20-year bird banding project in upland rainforest on the Paluma Range, north-eastern Queensland.

Results […]
The diet of Pied Currawongs Strepera graculina in eucalypt woodland near Armidale, New South Wales, was studied by analysis of stomach contents of 21 birds collected in October-December 2002.
