Little Shrikethrush

Identification

The little shrikethrush is a passerine bird in the family Pachycephalidae, also known as the brown shrike-flycatcher or rufous shrike-thrush. Its scientific name, Colluricincla megarhyncha, references its distinctive large bill—the specific epithet combining the Ancient Greek words for "much" and "bill." The species exhibits considerable variation across its range, with sixteen recognized subspecies displaying different plumage characteristics across Australia and New Guinea.

Range & Habitat

The little shrikethrush is found throughout New Guinea and across north and east Australia, with its range extending from the Kimberley region of northwestern Western Australia eastward through the Northern Territory and into Queensland, with populations also recorded as far south as central New South Wales. The species inhabits subtropical and tropical moist lowland forests as well as subtropical and tropical moist montane forests, making it a bird of well-wooded, humid regions.

Across New Guinea, multiple subspecies occupy different regions including the Bird's Head Peninsula, various offshore archipelagos such as the Aru Islands, D'Entrecasteaux Archipelago, Trobriand Islands, and Raja Ampat Islands, as well as mainland populations throughout the island's diverse forest regions. This wide distribution across multiple geographic areas has led researchers to identify at least eight separate genetic clades, suggesting the species may eventually be split into several distinct species pending further research.

Behaviour & Diet

While detailed behavioral observations remain limited in available literature, the little shrikethrush's common names suggest it exhibits characteristics of both shrikes and thrushes. Notably, toxicological studies have revealed that specimens of this species contain traces of batrachotoxins, the same poisonous compounds found in the secretions of Central and South American poison dart frogs. This remarkable discovery indicates an unusual biochemical profile for an Australian and New Guinean bird species.

Best Time & Places to See It

The little shrikethrush's preference for humid, forested habitats means it is best encountered in wet lowland and montane forests. In Australia, birders should focus on northeastern Queensland and the northern regions, where the species is more readily found. In New Guinea, the bird's presence across numerous subspecies and islands suggests it is reasonably widespread, though its forest habitat preference means it may be locally distributed and sometimes difficult to locate.

Photography Tips

The species' forest habitat and smaller size present moderate challenges for photographers. Success requires patience and early-morning visits when birds are most active. The bird's large, distinctive bill offers a useful identifying feature to focus on in photographs. Photographers should be prepared for the dappled, low-light conditions typical of moist forest interiors and consider bringing telephoto lenses to capture distant subjects without disturbing the bird in its natural habitat.
