Psarocolius montezuma
Drawn from open occurrence records in and around Tortuguero, 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, February, March, April, May, July, October and December. 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: 7 squares of 25 km carry records for Montezuma Oropendola in and around Tortuguero, and the 11,401 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.
Tortuguero, Arenal and Manuel Antonio are among the four atlas places where the Montezuma Oropendola is recorded, with records concentrating in Costa Rica, Mexico, Honduras, Belize and Guatemala. The atlas holds about 305,000 records of this bird from seven countries, and the map shows where these observations concentrate.
Of the 102 species with an atlas page recorded in and around Tortuguero, the Montezuma Oropendola is the most recorded.
