Rare
Under 5% of wildlife watchers report a Mottle-cheeked Tyrannulet sighting in Iguaçu National Park on a given day, based on 71 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 217th most-seen of the 346 birds we can rate there. Over three days the chance rises 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 Mottle-cheeked Tyrannulet in Iguaçu National Park 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 Mottle-cheeked Tyrannulet sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 6
Of the 6 parks where we can rate Mottle-cheeked Tyrannulet sightings, Iguaçu National Park ranks 6th at under 5%. The best odds are in Itatiaia National Park (Brazil, about 20%), Serra dos Órgãos National Park (Brazil, about 10%) and El Palmar National Park (Argentina, about 10%).
GBIF citizen-science records
It is estimated from how often the Mottle-cheeked Tyrannulet is recorded against all the birds logged in Iguaçu National Park (71 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.
