Under 5% of wildlife watchers report a Unicoloured Blackbird sighting in Buenos Aires on a given day, based on 86 verified sightings from GBIF citizen-science data. It is the 200th most-seen of the 274 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Unicoloured Blackbird in Buenos Aires on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Unicoloured Blackbird is recorded against all the birds logged in Buenos Aires (86 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.
