Asio flammeus (Short-eared Owl)

Language: French; Spanish

Wikipedia Abstract

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, although its very short tufts are usually not visible. The short-eared owl is found in open country and grasslands. The scientific name is from Latin. The genus name Asio is a type of eared owl, and flammeus means "flame-coloured".
