Bohemian Waxwings are sleek, masked birds with unusual red, waxy deposits at the tips of their secondary feathers. They are grayish-brown with white and yellow wing-patches and yellow terminal tail-bands. They have distinctive crested heads, black throats, and black masks lightly lined with white. Their heads have a rufous tinge, and their undertail coverts are rufous. Juveniles have most of the aforementioned field marks, but are mottled gray-brown and lack the feather-tips. The feather-tips seem to increase in number and size as the birds age.
