Waxwings (Bombycillidae)
Species
Waxwings are starling-sized arboreal birds, with a prominent crest and a "cross" expression. They have stocky bodies and short tails, and fly on starling-like pointed wings. From time to time large numbers of Waxwings leave their native forests, and occur in more open landscapes to the south. These "irruptions" are triggered when high populations coincide with a crop failure in rowan and other berries.
 
Three species are found in the boreal zone of the northern hemisphere. One species breeds in Europe.
