Oreocharis (Salvadori, 1876), Paramythia (De Vis, 1892) The painted berrypeckers, Paramythiidae, are a very small bird family restricted to the mountain forests of New Guinea.
The smallest species, the tit berrypecker, ranges from 12–14 cm in length and weighs around 17–21 g. The larger crested berrypeckers are 19–22 cm in length and weigh 36–61 g. The variation in size in the crested berrypecker is due to differences in altitude (Rapoport's rule), with birds being larger at higher altitudes.
Both genera have short necks, moderately long and broad rounded wings, and plump bodies.
In the tit berrypecker the plumage is sexually dimorphic, with the male having bright yellow patches on the face, wing and chest but the female being overall duller.
Both sexes of the crested berrypeckers are similar, but the species exhibits instead some variation between two subspecies.
Both genera have unique filoplumes (hairlike feathers) on the flanks that are not visible in the field and the function of which is unknown.
It is unknown if the three species make any migratory movements, although it has been suggested that the tit berrypecker may be partly nomadic.
They are common within their ranges and while some of their montane habitat has been cleared for agriculture large areas remain intact.
