Cedar Waxwing (Bombycilla cedrorum)

Most waxwing tail tips are yellow, but a small percentage are orange.

Waxwings are named for the red waxy substance produced at the tips of the secondary flight feathers.

All of these photos were taken through my office window while sitting at my desk at Duke with only a 100mm macro lens.

Flocking in the treetop just after sunrise, these waxwings are preparing to descend on the nearby sapsucker wells and fruiting hollies.
