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 common kestrel (Falco tinnunculus), also known as the European kestrel, Eurasian kestrel or Old World kestrel, is a species of predatory bird belonging to the kestrel group of the falcon family Falconidae. In the United Kingdom, where no other kestrel species commonly occurs, it is generally just called "kestrel". [2]
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 ...
The West Palearctic-Afrotropical and the North-South American migratory systems are fundamentally different from the East Palearctic-Indomalayan system, owing to the presence versus absence of ecological barriers." [26] Maximum entropy modelling can help in answering the question: why species winters at one location while the others are ...
BuzzFeed collected McDonald's cups from different countries to see just how they compared -- and (un)surprisingly, cups in the USA were the biggest by far. In America, a small drink is 16 oz., a ...
American kestrel. Order: Falconiformes Family: Falconidae. Falconidae is a family of diurnal birds of prey, notably the falcons and caracaras. They differ from hawks, eagles, and kites in that they kill with their beaks instead of their talons. Collared forest-falcon, Micrastur semitorquatus (A) LC; Crested caracara, Caracara plancus LC
