In 1844 Strickland moved it to genus Suiriri "for the present", expressing reluctance to place it in genus Satrapa which he had erected.
The yellow-browed tyrant is the only member of genus Satrapa and has no subspecies. The yellow-browed tyrant is 15 to 16.5 cm (5.9 to 6.5 in) long and weighs about 20 g (0.71 oz).

Rare
Under 5% of wildlife watchers report a Yellow-browed Tyrant sighting in Rio de Janeiro on a given day, based on 35 verified sightings from GBIF citizen-science data. It is the 188th most-seen of the 278 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 Yellow-browed Tyrant in Rio de Janeiro on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Yellow-browed Tyrant sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
7th of 10
Of the 10 cities where we can rate Yellow-browed Tyrant sightings, Rio de Janeiro ranks 7th at under 5%. The best odds are in Rosario (Argentina, about 10%), Buenos Aires (Argentina, about 10%) and Curitiba (Brazil, about 10%).

GBIF citizen-science records
It is estimated from how often the Yellow-browed Tyrant is recorded against all the birds logged in Rio de Janeiro (35 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.
