; class Aves, order Passeriformes)
A family of variable, soft-plumaged, mostly crested birds that inhabit forests, plains, and deserts, feeding on fruit and nesting in trees. The three species of Bombycilla (waxwings) are brown-grey birds with crests, and secondaries that have red, wax-like tips. The tail is tipped with yellow or red. They have short, stout bills, and short legs. Waxwings are gregarious in winter. Hypocolius ampelinus (hypocolius) is a blue-grey bird with a black mask, white-tipped black primaries, and a black-tipped tail. Its bill is slightly hooked, and its legs are short and strong. It inhabits open scrub with trees, feeds on berries and insects, and nests in trees and bushes. It occurs in south-western Asia and is sometimes placed in a family of its own, Hypocolidae. There are five genera in the family, with eight species, although the silky flycatchers are sometimes placed in a separate family Ptilogonatidae. They are found in N. and Central America, Europe, and Asia.
