The kestrel is one of Britain's most common birds of prey and can be
easily identified hovering low over the ground searching for prey.
It hovers by flying into a light headwind and making continuous
small adjustments of its wings and tail while it hangs on an rising
draught of air.
This allows it to keep its head perfectly still and to spot the
slightest movement on the ground below. When suitable prey is in its
sight, it drops vertically to the ground and grabs it in its talons,
killing it with a swift bite. Prey is mostly small mammals such as
voles, but kestrels are adaptable birds and will switch to beetles,
earthworms or even snails. They also frequently use pylons or
telegraph poles as vantage points to spot prey, saving themselves
the effort of hovering.
In more northerly and westerly areas they often migrate south at the
end of the breeding season, but return the following spring to form
their territories. In winter many more kestrels visit from the
Netherlands and Scandinavia.
