|Eastern Barn Owl (Tyto alba)|
The Eastern Barn Owl, the only tytonid owl found in eastern Canada, is easily distinguished from other owl species. Barn Owls have heart-shaped facial discs and dark, almost black eyes. Both sexes are ochre to cinnamon above, with patches and speckles of deeper browns. While males have ghostly white faces, breasts, bellies and underwings, females have rusty facial discs and rusty, spotted bellies and underwings (see above). They lack ear-tufts. Eastern Barn Owls are larger and lighter than their western counterparts. Unlike most owls in North America, they have almost bare feet.
The Barn Owl is currently on the COSEWIC (Committee on the Status of Endangered Wildlife in Canada) endangered species list, a curious fact as this species is extremely prolific and can have several clutches in a single year. In fact, Canada is at the northern end of its range due to the cold winter temperatures. The Barn Owl inhabits open country; feeding on field rodents and (since the colonization of Canada) utilizing warmth generated in barns by farm animals. Unfortunately, as technology has advanced, habitiat loss has occurred. In recent years humans have exchanged working animals for mechanical vehicles and pastureland for row crops. The average family that once required horses to travel has forgone them for cars. Therefore there are fewer warm barns for the owls to breed in and less animal feed for their prey (mice and rats) to thrive on. Luckily, Barn Owls are still common in states where livestock farming is predominant and barns and animal feed are accessible.
