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

Taxonomy[edit]

In their 1999 study, Schodde and Mason recognise two adjoining subspecies, O. s. spaldingii and O. s. melasmenus with a zone of intergradation.[2]

Description[edit]

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[edit]

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

Behaviour[edit]

Orthonyx spaldingii (male)

Diet[edit]

Mainly invertebrates, but also small vertebrates.

Voice[edit]

Continuous chattering, singing and other complex vocalisations.

Breeding[edit]

Nests on or near ground, often on ferns, stumps or logs. Builds a bulky, dome-shaped stick-nest with a clutch of one, possibly sometimes two, white eggs.
