Description
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.
