アメリカチョウゲンボウ Falco sparverius

Petite falcon roughly the same size as Mourning Dove, but with a larger head and wider tail. In flight, note long, narrow wings and square-tipped tail. Often seen perched on telephone wires, along roadsides, in open country with short vegetation and few trees. From a perch or hovering, they usually drop to the ground to snatch small mammals and insects. Nests in cavities. Widespread across the Americas.
