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 →

Rare
Under 5% of wildlife watchers report a Black Jacobin sighting in Iguazú National Park on a given day, based on 126 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 203rd most-seen of the 343 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May to August
In those months about 10% of wildlife watchers report a Black Jacobin in Iguazú National Park on a given day, against under 5% in September to April, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Black Jacobin sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 7
Of the 7 parks where we can rate Black Jacobin sightings, Iguazú National Park ranks 5th at under 5%. The best odds are in Serra dos Órgãos National Park (Brazil, about 40%), Itatiaia National Park (Brazil, about 30%) and Tijuca National Park (Brazil, under 5%).
Same family: Trochilidae
The closest relatives of the Black Jacobin that you can see in Iguazú National Park (family Trochilidae, Hummingbirds) are Violet-capped Woodnymph (about 20%), Versicolored Emerald (about 20%) and Gilded Hummingbird (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black Jacobin is recorded against all the birds logged in Iguazú National Park (126 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.
