The American kestrel (Falco sparverius) is the smallest and most common falcon in North America. Though it has been called the American sparrowhawk, this common name is a misnomer; the American kestrel is a true falcon, while the Eurasian sparrowhawk, Accipiter nisus, is not in the Falco genus and is thus genetically unrelated to the American ...
The American kestrel is the only New World species termed "kestrel". The molecular data of Groombridge [ 1 ] as well as morphological peculiarities (like grey wings in males and a black ear-spot) and biogeography , strongly support the view that this species, among the Falco falcons, is not a kestrel at all in the phylogenetic sense but perhaps ...
Falconidae is a family of diurnal birds of prey and includes caracaras, laughing falcon, forest falcons, falconets, pygmy falcons, falcons and kestrels.They are small to medium-sized birds of prey, ranging in size from the black-thighed falconet, which can weigh as little as 35 grams (1.2 oz), to the gyrfalcon, which can weigh as much as 1,735 grams (61.2 oz).

A study of mtDNA cytochrome b sequence data of some kestrels [17] identified a clade containing the common kestrel and related "malar-striped" species, to the exclusion of such taxa as the greater kestrel (which lacks a malar stripe), the lesser kestrel (which is very similar to the common, but also has no malar stripe), and the American ...
Though the merlin is only slightly larger than the American kestrel in dimensions, it averages about one third to one half larger by weight, with this weight mostly being extra muscle that gives it greater speed and endurance than the kestrel. [43] Like the American kestrel, the merlin offers the modern falconer the ability to hunt year round ...
