Kestrels nest in cavities excavated by woodpeckers, particularly Northern Flickers, but they also accept artificial nest boxes. They breed most readily in open habitats with plentiful hunting perches. Like shrikes they too are expert mousers, and they also take small birds,bats,insects,reptiles, and even fishon rare occasions.
