Short-tailed hawk : ウィキペディア英語版 | Short-tailed hawk
The short-tailed hawk (''Buteo brachyurus'') is an American bird of prey in the family Accipitridae, which also includes the eagles and Old World vultures. As a member of the genus ''Buteo'', it is not a true hawk and thus also referred to as a "buteo" or (outside North America) "buzzard". The white-throated hawk (''B. albigula'') is a close relative and was formerly included in the species ''B. brachyurus''. ==Range== Short-tailed hawks breed in the tropical and subtropical Americas from southeastern Brazil and northern Argentina north through Central America to northern Mexico, as well as in southern Florida, USA. This species is generally found below ASL and most common below . It is replaced by the white-throated hawk (''B. albigula'') in the Andes of southern Colombia and south to central Argentina and Chile; the short-tailed hawk is found in the Cordillera Central and Cordillera Occidental of Colombia, while ''B. albigula'' occurs south of these locales.〔 As far as is known, ''B. brachyurus'' is a year-round resident except that most of the Florida population migrates in winter to the southern tip of the state, including the Keys. It is somewhat habitat adaptable but only passes areas with dense human populations when foraging. The species may be found in wooded savannah, patchy woodlands near water, cypress swamps, mangrove swamps or high pine-oak woodlands. In the tropics, it is most common in lowland foothills.〔 Most of what is known about its natural history has been studied in the Floridian population, and might not apply to birds at the south of the species' range. In general, this species is associated with woodland, often near water.
