🦅American Kestrel

Falco sparverius Linnaeus, 1758

The American kestrel is the smallest and most common falcon in the Americas. Though it has been called the American "sparrow hawk", this now obsolete vernacular name is a misnomer; the American kestrel is a true falcon, while neither the Eurasian sparrowhawk nor the other species called sparrowhawks are in the family Falconidae, hence only very distantly related to the American kestrel. It has a roughly two-to-one range in size over subspecies and sex, varying in size from about the weight of a blue jay to a mourning dove. It is a very successful species, occurring almost throughout North and South America except for the Arctic fringes of North America, and the densest tropical Amazon rainforest areas; it has evolved into 17 subspecies adapted to different environments and habitats throughout the region. It exhibits sexual dimorphism in size and plumage, although both sexes have a rufous back with noticeable barring. Its plumage is colorful, and juveniles are similar in plumage to adults.
