This is a group of passerine birds characterised by soft silky plumage and unique red tips to some of the wing feathers. In the Bohemian and Cedar Waxwings, these tips look like sealing wax, and give the group its name.
These are arboreal birds of northern forests. They live on insects in summer and berries in winter.
They are not true long-distance migrants, but wander erratically outside the breeding season and move south from their summer range in winter. In poor berry years huge numbers can erupt well beyond their normal range.
Some authorities (including the Sibley-Monroe checklist) place the silky-flycatchers, and the Hypocolius, in family Bombycillidae along with the waxwings.
