The Amazonian black-tyrant (Knipolegus poecilocercus) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is particularly native to riverbanks of the Amazon rainforest. The Amazonian black tyrant was formally described by August von Pelzeln in 1868 as Empidochanes coecilocerecus. It was later transferred to genus Phaeotriccus which was still later merged into Knipolegus.
The Amazonian black tyrant is monotypic. It is called "maria-preta-do-igapó" in Brazilian Portuguese, "Viudita-negra Amazónica" in Ecuadorian and Peruvian Spanish, and "Atrapamoscas Remoloncito" in Venezuelan Spanish. The Amazonian black tyrant is about 12.7 to 13.5 cm (5.0 to 5.3 in) long and weighs about 14 g (0.49 oz). It has unusually large eyes. Adult males are almost entirely glossy black with a slight bluish sheen. Their primaries have a brownish tinge. Adult females have a mostly olive-brown head and upperparts with grayish white lores and eye-ring and rufous uppertail coverts. Their wings are dusky with buff edges on the flight feathers and cinnamon-buff tips on the coverts that show as two wing bars. Their tail is dusky with cinnamon edges... Wikipedia →

Rare
Under 5% of wildlife watchers report an Amazonian Black-Tyrant sighting in Amacayacu National Natural Park on a given day, based on 25 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 289th most-seen of the 436 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.
February and May
In those months about 10% of wildlife watchers report an Amazonian Black-Tyrant in Amacayacu National Natural Park on a given day, against under 5% in March–April and June–January, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Amazonian Black-Tyrant sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Amacayacu National Natural Park, in our data
Amacayacu National Natural Park is the only park on Wallace's Line with enough records to rate Amazonian Black-Tyrant sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Amazonian Black-Tyrant is recorded against all the birds logged in Amacayacu National Natural Park (25 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.
