The Little Owl is the smallest of our owls, being no bigger than a Starling in length. The best time to see one is in the evening, when birds will catch the last hour or so of the sunshine, half hidden in the branches of a tree.
Little Owls are birds of farmland, eating lots of worms and insects, which they catch while stomping about fields at night. They nest in holes in trees or sometimes in rabbit burrows. Occasionally Little Owls will move into a large nest box but they are more likely to be attracted to special nest boxes (PDF, 2.46 MB).
