The Chowchilla (Orthonyx spaldingii) is a passerine bird in the family Orthonychidae. It is endemic to Australia.

Taxonomy

In their 1999 study, Schodde and Mason recognise two adjoining subspecies, O. s. spaldingii and O. s. melasmenus with a zone of intergradation.

Description

Unmistakable thrush-like, ground-dwelling, birds. Males and females largely dark brown with white eye-ring, tail-feather shafts extend as spines beyond feather-vanes; males with white throat, breast and belly; females with bright rufous throat and upper breast, white lower breast and belly.

Distribution and habitat

The Chowchilla is restricted to upland and lowland tropical rainforests of north-eastern Queensland.

Behaviour

Mainly invertebrates, but also small vertebrates.

Continuous chattering, singing and other complex vocalisations.

Breeding
