Their wings are brownish gray with whitish... Wikipedia →

Rare
Under 5% of wildlife watchers report a Caatinga Black-Tyrant sighting in Chapada Diamantina National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 258th most-seen of the 271 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Caatinga Black-Tyrant in Chapada Diamantina National Park on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Caatinga Black-Tyrant sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Chapada Diamantina National Park, in our data
Chapada Diamantina National Park is the only park on Wallace's Line with enough records to rate Caatinga 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 Caatinga Black-Tyrant is recorded against all the birds logged in Chapada Diamantina National Park (7 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.
