With luck
About 10% of wildlife watchers report a Lemon-chested Greenlet sighting in Rio de Janeiro on a given day, based on 442 verified sightings from GBIF citizen-science data. It is the 57th most-seen of the 278 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
January and April
In those months about 20% of wildlife watchers report a Lemon-chested Greenlet in Rio de Janeiro on a given day, against about 10% in February–March and May–December, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Lemon-chested Greenlet sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Rio de Janeiro, in our data
Rio de Janeiro is the only city on Wallace's Line with enough records to rate Lemon-chested Greenlet sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Lemon-chested Greenlet is recorded against all the birds logged in Rio de Janeiro (442 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.
