Thk Motmot and His Tail. 



Mexican self-mutilating bird in Mr. Beebe's camp. Tail is long and 



greenish-blue in color, while the two central feathers, still longer 



than the others, are bitten bare of barbs for an inch of length, 



each feather being trimmed by the bird's beak into a 



full-veined racket. Lower picture shows feathers 



after bird has commenced the mutilation 



and after it has been completed.
