The American Kestrel, or Sparrow Hawk (Falco sparverius) is the smallest Falcon in the US. In this sample a male has "bounced" a Cooper's Hawk from a Cottonwood tree along the Verde River, in Central Arizona. He continued to chase and harass the Cooper's until they were out of sight. The sound is very like that of a Killdeer at a distance.
