Owls, with their round heads and large forward-facing eyes, are one of Britain’s most recognisable species. There are five species of owl in Britain, including the Barn owl, Tawny owl, Little owl, Short-eared owl and Long-eared owl. The Tawny owl is the most common owl species in Britain. Owls can famously turn their head through 270 degrees and are able to look behind them. Although owls have binocular vision, their forward-facing eyes cannot move in their sockets, so they must turn their heads instead.
