Short-eared owls are nomadic, that is they move around the countryside, gathering where the populations of voles and mice are highest. The short-eared is the owl most likely to be seen by day in Britain, as it flies over fields or marshes, quartering the ground for prey. Groups of birds may be spotted hunting together in this way. They glide turn and hover low over the ground, then drop with raised wings, flying up quickly if they miss their prey. The owl relies on its excellent hearing and sight to locate its prey. If successful, the prey is seized in the bird's sharp talons and swallowed head-first while the bird is still on the ground.
When it is not hunting, the owl often sits quietly on a post, or in a tree, waiting and watching. It may also regurgitate pellets containing the indigestible remains of food such as fur and bones.
