Rhagologus leucostigma
The Mottled Berryhunter, Rhagologus leucostigma, is a cryptic, medium-sized passerine native to the montane forests of New Guinea. Measuring approximately 15-16 cm (6-6.3 inches) in length and weighing 24-29 grams, its plumage is characterized by olive-brown upperparts and a distinctive mottled or streaked pattern across its pale grey throat, breast, and flanks, providing excellent camouflage amidst its arboreal habitat. Key field marks include its overall muted coloration, the subtle but dis...
Exclusively inhabiting montane and upper montane rainforests, this species is found at elevations typically ranging from 1,200 to 2,700 meters (3,900 to 8,900 feet) above sea level.
Primarily frugivorous, consuming a variety of berries and small fruits, supplemented by arthropods like insects and spiders, typically gleaned from foliage and branches.
Mottled Berryhunters are primarily diurnal, often observed singly or in pairs, but frequently join mixed-species foraging flocks, moving deliberately through the mid-story and sub-canopy. They employ a gleaning foraging strategy, carefully searching foliage, branches, and moss for fruits and inse...
The Mottled Berryhunter is endemic to the island of New Guinea, where it is primarily found in the montane and upper montane rainforests. Its distribution spans across both the Indonesian provinces of West Papua and Papua, and the independent nation of Papua New Guinea. Within this broad region, ...
