The variable shrikethrush (Colluricincla fortis) is a species of bird in the family Pachycephalidae.

Taxonomy and systematics

This species was formerly considered a conspecific member of the little shrikethrush complex. Genetic investigations of New Guinea populations of the little shrikethrush indicate high levels of genetic divergence, suggesting it comprised more than one species.[1]

Subspecies

Currently, three subspecies are recognized:[2]

• C. f. despecta - (Rothschild & Hartert, 1903): Found on southern coast of south-eastern New Guinea
• C. f. fortis - (Gadow, 1883): Originally described as a separate species in the genus Pachycephala. Found on D'Entrecasteaux Archipelago (off southeastern New Guinea)
• C. f. trobriandi - (Hartert, 1896): Found on Trobriand Islands

It is found in New Guinea. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests.
