The hooting you hear at night is a call, which determines each bird's territory. They are so territorial that sometimes they will even fight with and kill other intruding owls. Females are again bigger than males. Colours are very similar although tawny owls come in a varied range of colours from almost grey through to almost white. The most common colour to be seen is a mottled brown wow gold. Tawny owls like barn owls prey upon mice and voles but also garden birds up to the size of black birds and thrush. Eyesight is what this owl mainly uses at night to spot it's quarry. It’s large eyes take in lots of light for good night vision.
