The swallow-tailed kite (Elanoides forficatus) is a pernine raptor which breeds from the southeastern United States to eastern Peru and northern Argentina. It is the only species in the genus Elanoides. Most North and Central American breeders winter in South America where the species is resident year round.
The swallow-tailed kite was first described as the "swallow-tail hawk" and "accipiter cauda furcata" (forked-tail hawk) by the English naturalist Mark Catesby in 1731. It was given the binomial scientific name Falco forficatus by Carl Linnaeus in the 10th edition of Systema Naturae, published in 1758; he changed this to Falco furcatus in the 12th edition of 1766. The latter spelling was used widely during the 18th and 19th centuries, but the original spelling has precedence. The genus Elanoides was introduced by the French ornithologist Louis Pierre Vieillot in 1818. The name is from Ancient Greek elanos for "kite" and -oides for "resembling".
The species is 50 to 68 cm (20 to 27 in) in length, with a wingspan of approximately 1.12–1.36 m (3.7–4.5 ft). Male and female individuals appear similar. The body weight is 310–600 g (11–21... Wikipedia →

GBIF citizen-science records
It is estimated from how often the American Swallow-tailed Kite is recorded against all the birds logged in Santa Cruz de la Sierra (14 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.
