; class Aves, order Passeriformes)
A family of small to medium-sized birds which have brightly coloured, iridescent plumage and elaborate plumes on the head, back, wings, and tail; some also have wattles. Females tend to be dull-coloured. The bill is short to long, straight and slender, and highly decurved or hooked. The wings are short and rounded, the tail short and square to long and graduated. The birds are arboreal, feed on insects, frogs, lizards, fruit, and seeds, and nest in a cavity or tree fork. Their plumes are used in highly elaborate displays which also involve unusual vocal sounds. There are 20 genera, with 43 species, found mainly in New Guinea, but also in Australia and the Moluccas.
