Coragyps atratus
Drawn from open occurrence records in and around Arenal, 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. 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: 4 squares of 25 km carry records for Black Vulture in and around Arenal, and the 53,496 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.
Arenal, Monteverde and Tortuguero are among the six atlas places where the Black Vulture is recorded, with records concentrating in the United States, Costa Rica, Panama, Colombia and Mexico. The atlas holds about 2.3 million open records of the bird across 14 countries, and its map follows where these records gather.
Of the 193 species with an atlas page recorded in and around Arenal, the Black Vulture is the 3rd most recorded.
