| Birds within the family Strigidae are known as typical owls. They vary greatly in size, but all tend to have large heads, short tails, cryptic plumage, massive eyes relative to their body size, and round facial discs. Asymmetrical facial discs allow owls to localize the source of sounds. The family is generally arboreal. Their wings are generally broad and rounded. Like other birds of prey many owl species exhibit reverse sexual dimorphism in size, where females are larger than males. Because of their nocturnal habits | they tend not to exhibit sexual dimorphism in their plumage. The toes and tarsus are feathered in some species. The genus Glaucidium have eye patches on the nape area. Numerous nocturnal species have ear-tufts, feathers on the sides of the head that are thought to have a camouflage function breaking up the outline of a roosting bird. There are 11 genera and 29 species of owls known to occur in Peru. Photo (left): Cinnamon Screech-Owl ©Alejandro Alarcon. (right) Short-eared Owl ©Carlos Gussoni. |
