Orthonyx novaeguineae
The Papuan Logrunner (Orthonyx novaeguineae) is an enigmatic and captivating resident of New Guinea's montane rainforests, renowned for its striking plumage and unique foraging style. Measuring approximately 18-20 cm (7-8 inches) in length and weighing around 40-60 grams, males feature dark brown upperparts, a rufous rump, and a blackish tail, sharply contrasted by a brilliant white throat and breast, neatly bordered by a distinct black band across the upper chest.

Exclusively inhabiting dense, wet montane rainforests and mossy cloud forests of New Guinea, typically found at elevations between 1,000 and 2,800 meters (3,300 to 9,200 feet) above sea level, preferring thick undergrowth and abundant leaf litter.
Primarily insectivorous, their diet consists almost exclusively of invertebrates, including insects, spiders, and worms, which they uncover by vigorously raking through leaf litter on the forest floor.
Papuan Logrunners are diurnal and primarily terrestrial, spending most of their time foraging on the forest floor. Their unique foraging method involves powerful, synchronized sweeps of their strong feet, raking aside leaf litter in an arc to expose invertebrates, a behavior aptly termed "logrunn...
The Papuan Logrunner is endemic to the mountainous regions of New Guinea, where it maintains a year-round resident distribution. Its primary range encompasses the central cordillera, including the Snow Mountains, Star Mountains, and Owen Stanley Range, extending to isolated mountain blocks such a...
