Barn Owl ( Tyto alba )

The Barn Owl (Tyto alba) is the most widely distributed species of owl, and one of the most widespread of all birds. It is also referred to as Common Barn Owl, to distinguish it from other species in the barn-owl family Tytonidae.
Barn owls tend to measure between 25 and 40cm tall and adult barn owls can have a wingspan of up to 110cm long. The wing span of the barn owl is however dependent on the species of barn owl so some owls may be smaller, where other species of barn owl may be much bigger. Surprisingly, these common barn owls do not make the hoot sound that can often be heard at night. Instead the owls produce a high-pitched scream and can also hiss in a similar way to a cat or snake if the barn owl feels threatened. Barns owls can be most commonly seen in the open countryside and along river banks, fields and even the verges on the side of the road. Barn owls are nocturnal animals meaning that typically barn owls rest during the light day time hours and emerge at dusk to begin a night of hunting.
