The Barn Owl (Tyto alba) is a medium-sized, tawny coloured owl that, with the exception of Antarctica, has worldwide distribution. Like most owls the Barn Owl is considered to be nocturnal. Like all owls, it is predatory bird. In the Barn Owl’s case, members of the species are said to enjoy (or specialize, in the biological parlance) in small ground mammals—rodents, for example. In Eastern North America, the majority of their diet would include Meadow Voles (Microtus pennsylvanicus) and Deer Mice (Peromyscus maniculatus). Barn Owls strike a distinct-look with their lack of ear tufts (a misnomer of sorts as the tufts—the “horns ” of a Great Horned Owl, Bubo virginianus—are not ears and not associated with hearing at all) and their distinct heart-shaped facial disc (which is associated with hearing, but that’s another story for another time). As their common name suggests they can be found living in barns, on a nest made from the regurgitated un-digestible remains of those Meadow Voles and Deer Mice they hunt. Of course Barn Owls are not just limited to barns, but nest in silos, abandoned buildings and tree cavities too. Arguably, this should make their name
