The blue-crowned motmot is a colorful Central and South American bird with a striking face and red eyes. The male also has two unusual tail feathers with bare shafts and racket tips. Racket... as in tennis racket.
The feathers don't start out this way. When the male molts the feathers grow in normally but the middle radii are weakly attached to the shaft so they easily fall off during normal abrasion and preening. The result is a fancy tail during the breeding season.
In the wild, the racket tips are very noticeable because the males swings his tail like a pendulum when disturbed.
