Short-eared owl
The short-eared owl (''Asio flammeus'') is a species of typical owl (family Strigidae). Owls belonging to genus ''Asio'' are known as the eared owls, as they have tufts of feathers resembling mammalian ears. These "ear" tufts may or may not be visible. ''Asio flammeus'' will display its tufts when in a defensive pose. However, its very short tufts are usually not visible. The short-eared owl is found in open country and grasslands. The word ''flammeus'' is Latin for "flaming, or the color of fire".〔
