The Melanocharitidae, the berrypeckers and longbills, is a small bird family restricted to the forests of New Guinea. The family contains ten species in four (sometimes three) genera. They are small songbirds with generally dull plumage but a range of body shapes.
The berrypeckers are generally montane species, with only one, the black berrypecker, being found in lowland forest. In contrast the longbills live in lowland forests and low montane forests as well as on small islands around New Guinea. Amongst the berrypeckers there is a succession of species at different altitudes, with the black berrypecker being found in the lowlands, the mid-mountain berrypecker being found at lower altitudes (mid-montane) and the fan-tailed berrypecker being found near the treeline.
