Meet the American Kestrel
  • Scientific name: Falco sparverius.
  • Formerly known as Sparrow Hawk.
  • The smallest, most numerous, and most widespread North American falcon.
  • The only kestrel species that occurs in the Western Hemisphere.
  • Contains seventeen recognized subspecies.
  • Sexually dichromatic, meaning males and females have different plumages. Males have blue-gray wings, females have rufous wings. Tails also differ, the male showing a rufous tail with a black subterminal band, females show a rufous tail with black bars across the length of the tail.
  • Often seen in open areas with short ground vegetation.
  • Hunts by perching on limbs, fences, or wires or hovering if perch sites are limited.
  • Captures arthropods and small mammals on the ground, insects and small birds in flight.
  • Nests in natural cavities or those made by woodpeckers. Availability of suitable cavities may limit numbers in certain areas of breeding range; they will readily take to nest boxes.
