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.
Short-tailed hawks breed in the tropical and subtropical Americas from southeastern Brazil and northern Argentina north through Central America to the mountains of the Mexico-Arizona border area, as well as in southern Florida, United States; it is also found on the Caribbean island of Trinidad. This species is generally found below 4,500 ft (1,400 m) ASL and most common below 2,500 ft (760 m). 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... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Short-tailed Hawk is recorded against all the birds logged in Guayaquil (74 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
