American Kestrel

Falco sparverius ORDER: FALCONIFORMES FAMILY: FALCONIDAE

IUCN Conservation Status: Least Concern

North America’s littlest falcon, the American Kestrel packs a predator’s fierce intensity into its small body. It's one of the most colorful of all raptors: the male’s slate-blue head and wings contrast elegantly with his rusty-red back and tail; the female has the same warm reddish on her wings, back, and tail. Hunting for insects and other small prey in open territory, kestrels perch on wires or poles, or hover facing into the wind, flapping and adjusting their long tails to stay in place. Kestrels are declining in parts of their range; you can help them by putting up nest boxes.

Backyard Tips

American Kestrels take well to artificial nest boxes. To attract a breeding pair, the box should be put up by early February. Nail it to a tree 10 to 30 feet above the ground away from traffic and loud human activity. Attach a guard to keep predators from raiding eggs and young. Find out more about nest boxes on our Attract Birds pages. You'll find plans for building a nest box of the appropriate size at our NestWatch site.

Find This Bird

Scan fence posts, utility lines and telephone poles, particularly when driving through farmland. Or catch them by the hundreds at coastal migration sites—such as Cape May, New Jersey, or Kiptopeke, Virginia—in September or early October. Particularly in summer, listen for their shrill killy-killy-killy call to be alerted to when they're around.
