The American Kestrel (Falco sparverius), sometimes known as the Sparrow Hawk, is a small Falcon, and the only Kestrel found in the Americas. It is the most common falcon in North America, and is found in a wide variety of habitats. At 19–21 cm (7–8 in) long, it is also the smallest falcon in North America.
American Kestrels feed largely on small animals such as grasshoppers, dragonfly, lizards, mice, grubs, and voles. They will occasionally eat small birds.
The kestrel has also been reported to have killed snakes, bats, and squirrels
Three to seven eggs (typically four or five) are laid approximately 24–72 hours apart.
