Chick-provisioning and other Behaviour of a Pair of Torresian Crows Corvus orru

Abstract

Observations near Coffs Harbour (New South Wales) on one afternoon in week 3 of the nestling phase revealed that the presumed female Torresian Crow Corvus orru brooded for 35% of observation time (2.3 h), and both sexes fed the nestlings at a combined rate of 3.0 deliveries/h ( n = 7). Both sexes defended the nest against potential predators, and the female performed an undulating return flight, with calling, after evicting a raptor.
