Psarocolius decumanus
Drawn from open occurrence records in and around Tambopata National Reserve, aggregated onto a 25 km grid. A cell is matched by its centre, which can sit up to 16 km outside the boundary, so this covers the surrounding country too.
Occurrence records measure where people looked and found something, which is not the same as where the animal is. This is a relative likelihood, not a probability.
Records exist for January, February, March, April, May, June, July, August, September, October, November and December, with the widest coverage in January, March, May, June, July, August, September, October and November. A quiet month can mean the animal was absent, or that nobody was looking.
A grid cell is a square of the map, not a sighting: 6 squares of 25 km carry records for Crested Oropendola in and around Tambopata National Reserve, and the 3,700 records behind them were collected by other people and published openly. Nothing here counts animals, and a place with more records is not always a place with more animals.
Osa Peninsula is the atlas place where the Crested Oropendola is recorded, with records concentrating in Colombia, Venezuela, Panama, Brazil and Ecuador. The atlas holds about 171,000 open records of this bird across 13 countries, and the map shows where these sightings concentrate.
Of the 54 species with an atlas page recorded in and around Tambopata National Reserve, the Crested Oropendola is the 3rd most recorded.
