The slaty-backed chat-tyrant or chestnut-bellied chat-tyrant (Ochthoeca cinnamomeiventris) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Bolivia, Colombia, Ecuador, Peru, and Venezuela.
The slaty-backed chat-tyrant was formally described in 1843 as Muscicapa cinnamomeiventris, erroneously placing it in the Old World flycatcher family. It was eventually moved to genus Ochthoeca and for a time it, the maroon-belted chat-tyrant (O. thoracica) and the blackish chat-tyrant (O. nigrita) were considered conspecific. A study published in 1998 suggested that each of them should be raised to full species level. By 2006 the IOC had recognized the slaty-backed chat-tyrant as a species. BirdLife International's Handbook of the Birds of the World (HBW) recognized it in 2016 and the Clements taxonomy in 2022. However, the South American Classification Committee of the American Ornithological Society retains the blackish chat-tyrant as a subspecies of the slaty-backed.
The slaty-backed chat-tyrant is monotypic. The slaty-backed chat-tyrant is 12 to 13 cm (4.7 to 5.1 in) long and weighs 11 to 13 g (0.39 to 0.46... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Slaty-backed Chat-Tyrant is recorded against all the birds logged in Los Nevados National Natural Park (555 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.
