When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the oriole blackbird. Linnaeus included a brief description... Wikipedia →

With luck
About 10% of wildlife watchers report an Oriole Blackbird sighting in Sierra de la Macarena National Park on a given day, based on 141 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 79th most-seen of the 418 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Oriole Blackbird is recorded against all the birds logged in Sierra de la Macarena National Park (141 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.
