The black jacobin (Florisuga fusca) is a species of hummingbird in the family Trochilidae. It is found in Argentina, Brazil, Paraguay, and Uruguay. The black jacobin was traditionally placed in the monotypic genus Melanotrochilus, but voice, anatomy, and reproductive behavior place it in Florisuga with the white-necked jacobin. The species is monotypic.
The black jacobin is 12 to 13 cm (4.7 to 5.1 in) long. Males weigh about 9 g (0.32 oz) and females 8 g (0.28 oz). Adults of both sexes are mostly black, with a bronzy-olive lower back and uppertail- and wing-coverts. The flanks are white, the inner rectrices black, and the outer rectrices white with black tips. Juveniles are dark except for a wide cinnamon band on the center and sides of the throat and a white belly and outer rectrices.
The black jacobin is found in southeastern Brazil, approximately from Bahia south through Rio Grande do Sul and into eastern Uruguay, and separately in southeastern Paraguay, northeastern Argentina, and adjoining Brazil. There are also scattered records from sites outside its primary range. It mostly inhabits woodlands, gardens... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Black Jacobin is recorded against all the birds logged in Serra dos Órgãos National Park (246 verified sightings from 2019 to 2026), 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.
