Kestrel (Falco tinnunculus).
The Kestrel is typically seen in hovering flight. Young birds frequently use fence posts and perches from which to hunt. Males are strongly marked with slate grey heads and tails whereas the females have brown heads and tail. Young Kestrels graduate from hunting insects such as grasshoppers to larger prey like mice and voles.
