The brown-backed chat-tyrant (Ochthoeca fumicolor) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Bolivia, Colombia, Ecuador, Peru, and Venezuela. The brown-backed chat-tyrant's taxonomy is unsettled. The IOC, the Clements taxonomy, and BirdLife International's Handbook of the Birds of the World (HBW) assign it these four subspecies:
However, the South American Classification Committee of the American Ornithological Society (SACC) includes a fifth subspecies, O. f. superciliosa, that the other systems had also long included. It had been originally described in 1870 as a species and the SACC notes that at least one author early in the twentieth century continued to recognize it as one. HBW recognized that taxon as the rufous-browed chat-tyrant in 2016, Clements in 2022, and the IOC in 2023.
This article follows the four-subspecies model. The brown-backed chat-tyrant is 14.5 to 16 cm (5.7 to 6.3 in) long and weighs 16 to 19 g (0.56 to 0.67 oz). The sexes... Wikipedia →

Under 5% of wildlife watchers report a Brown-backed Chat-Tyrant sighting in Farallones de Cali National Natural Park on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 484th most-seen of the 542 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Brown-backed Chat-Tyrant in Farallones de Cali National Natural Park on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Brown-backed Chat-Tyrant is recorded against all the birds logged in Farallones de Cali National Natural Park (13 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.
