The family Bombycillidae, commonly known as waxwings and silky-flycatchers, is a small group of passerine birds found mainly in the Northern Hemisphere. Members of this family are medium-sized, highly social birds with soft, silky plumage and distinctive markings, including bright wing and tail tips that often appear waxy. They primarily feed on fruits and berries, though some species also consume insects, especially during the breeding season. Bombycillidae are known for their nomadic behavior, moving in flocks to follow fruit availability, and they typically build cup-shaped nests in trees. Their striking appearance and sociable nature make them a familiar and charismatic group in ornithology.
