Rare
Under 5% of wildlife watchers report a Blue-black Grassquit sighting in Rio de Janeiro on a given day, based on 131 verified sightings from GBIF citizen-science data. It is the 112th most-seen of the 278 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
October to December
In those months about 10% of wildlife watchers report a Blue-black Grassquit in Rio de Janeiro on a given day, against under 5% in January to September, the lowest months. Those are among Rio de Janeiro's wettest months, with about 190 mm of rain a month against 40 mm in August.

GBIF citizen-science records
It is estimated from how often the Blue-black Grassquit is recorded against all the birds logged in Rio de Janeiro (131 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.
