cedar waxwing \ce"dar wax"wing\, n. (Zool.)
a species of chatterer ({Bombycilla cedrorum}, formerly
{Ampelis cedrorum}) widely distributed over temperate North
America, so named from its frequenting cedar trees; -- called
also {cedar bird}, {cherry bird}, {Canada robin}, and
{American waxwing}. It is a brownish bird about 7 inches
long, between the size of a robin and a sparrow, has a crest
on the head, a black face mask, and a yellow-tipped tail. The
name comes from the black color of the tips of the wings,
like that of a black sealing wax. They sometimes are seen in
flocks.
