American Kestrel

American Kestrel
Falco sparverius
Hawk-like Birds | Family: Falcons, Falconidae

An estimated 13% of the species' North American population breeds within the Boreal Forest.



Unlike larger falcons, the "Sparrow Hawk" has adapted to humans and nests even in our largest cities, where it preys chiefly on House Sparrows. In the countryside it takes insects, small birds, and rodents, capturing its prey on the ground rather than in midair like other falcons. The female does most of the incubating and is fed by the male. The male calls as he nears the nest with food; the female flies to him, receives the food, and returns to the nest. After the eggs hatch, the male continues to bring most of the food. The young stay with the adults for a time after fledging, and it is not uncommon to see family parties in late summer.
