The bird of prey
The common buzzard (Buteo buteo)[2] is a medium-to-large bird of prey which has a large range. It is a member of the genus Buteo[2] in the family Accipitridae.[2] The species lives in most of Europe and extends its breeding range across much of the Palearctic as far as northwestern China (Tian Shan), far western Siberia and northwestern Mongolia.[2][1][3] Over much of its range, it is a year-round resident. However, buzzards from the colder parts of the Northern Hemisphere as well as those that breed in the eastern part of their range typically migrate south for the northern winter, many journeying as far as South Africa.[2][4]
The common buzzard is an opportunistic predator that can take a wide variety of prey, but it feeds mostly on small mammals, especially rodents such as voles. It typically hunts from a perch.[5] Like most accipitrid birds of prey, it builds a nest, typically in trees in this species, and is a devoted parent to a relatively small brood of young.[3] The common buzzard appears to be the most common diurnal raptor in Europe, as estimates of its total global population run well into the millions.[3
The first formal description of the common buzzard was by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Falco buteo.[7] The genus Buteo was introduced by the French naturalist Bernard Germain de Lacépède in 1799 by tautonymy with the specific name of this species.[8][9] The word buteo is Latin for a buzzard.[10] It should not be confused with the Turkey vulture, which is sometimes called a buzzard in American English.
The Buteoninae subfamily originated from and is most diversified in the Americas, with occasional broader radiations that led to common buzzards and other Eurasian and African buzzards. The common buzzard is a member of the genus Buteo, a group of medium-sized raptors with robust bodies and broad wings. The Buteo species of Eurasia and Africa are usually commonly referred to as "buzzards" while those in the Americas are called hawks. Under current classification, the genus includes approximately 28 species, the second most diverse of all extant accipitrid genera behind only Accipiter.[11] DNA testing shows that the common buzzard is fairly closely related to the red-tailed hawk (Buteo jamaicensis) of North America, which occupies a similar ecological niche to the buzzard in that continent. The two species may belong to the same species complex.[11][12] Two buzzards in Africa are likely closely related to the common buzzard based on genetic materials, the mountain (Buteo oreophilus) and forest buzzards (Buteo trizonatus), to the point where it has been questioned whether they are sufficiently distinct to qualify as full species. However, the distinctiveness of these African buzzards has generally been supported.[12][13][14] Genetic studies have further indicated that the modern buzzards of Eurasia and Africa are a relatively young group, showing that they diverged at about 300,000 years ago.[15] Nonetheless, fossils dating earlier than 5 million year old (the late Miocene period) showed Buteo species were present in Europe much earlier than that would imply, although it cannot be stated to a certainty that these would’ve been related to the extant buzzards.[16]
