Tawny Owls (Strix aluco) are a resident, sedentary and highly territorial breeding species in the UK. They are responsible for the most commonly heard owl sound, the classic, nocturnal ‘twit twoo’ call, with which most people are familiar: Tawny Owls are primarily a woodland species, but have adapted to live almost anywhere there are trees, including city parks, wooded urban and suburban gardens, farmland hedgerows and copses, as well as more extensive areas of woodland and forestry. Diet comprises predominantly small mammals, namely Wood Mice (Apodemus sylvaticus) and Bank Voles (Myodes glareolus), but can also include Field Voles (Microtus agrestis) if areas of prey-rich grassland are available within the territory. In addition they will take rabbits, moles, small birds, beetles, earthworms, frogs and even fish. They have been recorded eating carrion in times of hardship.
