The mottled berryhunter, also known as the mottled whistler (Rhagologus leucostigma), is a distinctive bird species with uncertain family ties, likely closely related to woodswallows, boatbills, and butcherbirds. This bird is the sole member of both its genus and family (Rhagologus and Rhagologidae, respectively). It inhabits the highland montane forests of New Guinea, thriving in the subtropical and tropical moist environments found there.
