white-winged chough

The smaller white-winged chough has similar plumage but has red eyes and is found mainly on the ground.

More recent studies have suggested a relationship with the Corcoracidae (the white-winged chough and apostlebird of Australia).

The magpie-lark, for example, was assigned to the same family as the white-winged chough, since both build unusual nests from mud rather than vegetable matter.

The white-winged chough of Australia, despite its name, is a member of the family Corcoracidae and only distantly related.

The white-winged chough will forage in litter and rotten wood for termites and beetles.

This may be due to helpers having relatively poorer body conditions at the end of the breeding season, similar to pied kingfisher and white-winged chough.

It is one of two remaining species, with the white-winged chough (Corcorax melanorhamphos), which differs in appearance but exhibits many behavioural similarities.

Corcorax melanorhamphos (White-winged chough)

The Australian white-winged chough, Corcorax melanorhamphos, despite its similar bill shape and black plumage, is only distantly related to the true choughs.

A White-winged Chough was on her elegant, mud cup; a pair of Crimson Rosellas poked in and out of their hollow.

It contains just two species in two genera, the white-winged chough, Corcorax melanorhamphos, and the apostlebird Struthidea cinerea.

The number of birds in the group may vary from two to twenty birds, six birds being typical in the white-winged chough and seven to nine birds in the apostlebird.

The differences in the bills reflect the differences in feeding ecology, with the apostlebirds using theirs for sparrow-like picking whereas the white-winged chough uses its bill to flick leaf litter around.

Highlights were many Yellow-plumed and Brown-headed Honeyeaters, a brief glimpse of a shy Crested Bellbird, a 70-80 strong flock of White-winged Chough, and again many small insectivores.

The white-winged chough (Corcorax melanorhamphos) is one of only two surviving members of the Australian mud-nest builders family, Corcoracidae, and is the only member of the genus Corcorax.

Communally breeding birds, such as the white-winged chough, the laughing kookaburra (Dacelo novaeguineae), and the apostlebird (Struthidea cinerea), are a feature of the ecosystems around the entrance to Carnarvon Gorge.

The bill of the apostlebird is short and deep, not unlike that of a finch, whereas the bill of the white-winged chough is long and curved, not unlike that of its Old World namesakes, the choughs.
