The Chowchilla (Orthonyx spaldingii) is a passerine bird in the family Orthonychidae. It is endemic to Australia.
In their 1999 study, Schodde and Mason recognise two adjoining subspecies, O. s. spaldingii and O. s. melasmenus with a zone of intergradation.
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.
Mainly invertebrates, but also small vertebrates.
Continuous chattering, singing and other complex vocalisations.
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.
