Little Owls (Athene noctua) are a highly sedentary species in the UK. They are particularly territorial in the breeding season and consequently very vocal, with a wide variety of vocalisations. Typical calls include a plaintive ‘kew’ ‘kew’ and a loud ‘wherrow’, repeated at regular intervals.
Little Owls establish their territory in the late winter and early spring, when males can be particularly noisy. Territory size varies throughout the year but is at its greatest prior to the breeding season when individuals may cover nearly 40Ha in the UK. This reduces to as little as 2Ha, as pairs provision young.
Diet consists primarily of crickets, grasshoppers and other invertebrates such as beetles and earthworms, as well as small mammals. Small birds are also taken during the breeding season.
Little Owls are most active at dawn and dusk, and after dark when most hunting occurs. However, they can frequently be seen during the middle of the day, basking in the sun on an exposed perch such as a telegraph pole, dead tree or isolated building. Rather than hunting on the wing, Little Owls usually hunt from a perch, typically a fence post. When prey is spotted they sometimes ‘bob up and down’ a few times before a typically short, low, undulating flight to the ground where they sometimes pursue prey on foot. Whilst perched on a post they blend into farmland environments extremely well and are easily overlooked.
