Tawny Owls are medium-sized owls with shortish tails, broad, shortish, round-tipped, convex wings and large round heads. Birds of two different colour phases can be seen in Finland with greyish or reddish brown plumage. They have streaking almost all over their plumage with darker colouring on their upper parts than their underparts. Their faces are a more uniform greyish brown or reddish brown with no streaking. Their large eyes are dark blackish brown. They are best distinguished from the similar Ural Owl by their smaller size, shorter tails and two whitish lengthwise streaks on their caps. Their legs are covered with feathers leaving only their brown claws visible. Their beaks are greenish yellow and their eyelids are reddish brown.
Tawny Owls may defend their young aggressively against human invaders.
