Under 5% of wildlife watchers report a Mottle-cheeked Tyrannulet sighting in Montevideo on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 143rd most-seen of the 178 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
July
In that month about 10% of wildlife watchers report a Mottle-cheeked Tyrannulet in Montevideo on a given day, against under 5% in August to June, the lowest months.

GBIF citizen-science records
It is estimated from how often the Mottle-cheeked Tyrannulet is recorded against all the birds logged in Montevideo (15 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.
