Possible
About 20% of wildlife watchers report a Mottle-cheeked Tyrannulet sighting in Itatiaia National Park on a given day, based on 334 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 111th most-seen of the 352 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Mottle-cheeked Tyrannulet is recorded against all the birds logged in Itatiaia National Park (334 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.
