Barn and Grass Owls (W)
From WikiBird
Tytonidae
Barn owls are medium to large sized owls with large heads and characteristic heart-shaped faces. They have long strong legs with powerful talons. The barn owls comprise two sub-families: the Tytoninae or Tyto owls (including the Common Barn Owl) and the Phodilinae or bay-owls.
The barn owls are a wide ranging family, absent only from northern North America, Saharan Africa and large areas of Asia. They live in a wide range of habitats from deserts to forests, and from temperate latitudes to the tropics.
The barn owls main characteristic is the heart-shaped facial disc, formed by stiff feathers which serve to amplify and locate the source of sounds when hunting. Further adaptations in the wing feathers eliminate sound caused by flying, aiding both the hearing of the owl listening for hidden prey and keeping the prey unaware of the owl. Barn owls overall are darker on the back than the front, usually a orange-brown colour, the front being a paler version of the back or mottled, although there is considerable variation even amongst species. The bay owls closely resemble the Tyto owls but have a divided facial disc, and tend to be smaller.
