Silky-flycatcher

The silky-flycatchers are a small family, Ptiliogonatidae, of passerine birds. The family contains only four species in three genera. They were formerly lumped with waxwings and hypocolius in the family Bombycillidae, and they are listed in that family by the Sibley-Monroe checklist. The family is named for their silky plumage and their aerial flycatching techniques, although they are unrelated to the Old World flycatchers (Muscicapidae) and the tyrant flycatchers (Tyrannidae).
