bombycilla cedrorum

from The Collaborative International Dictionary of English v.0.48
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.
