Although humanoid, tengus have very distinct, birdlike features, and many would say that they resemble crows more than they do humans. They have strong, thick beaks, as well as sharp talons at the ends of their arms and legs. Most of a tengu's body is covered in small feathers that range in color from dark brown and midnight blue to glossy black, with lighter colors being rare but not unheard of. Like many avian creatures, tengus have hollow bones, making them much lighter than other humanoids of their size, although few tengus possess the wings necessary to fly naturally. A tengu's speech might be punctuated by quick clucks or throaty cawing, and many tengus practice conversation diligently to rid themselves of these involuntary ticks. Ruf ing of the feathers and compulsive, jerky movements of the neck are other trademark habits. Tengus reproduce by laying eggs: the average tengu egg is about 11 inches in diameter and 16 inches tall and takes 4 months to hatch.
