Progne chalybea
Drawn from open occurrence records in and around Chapada dos Veadeiros National Park, 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: 1 square of 25 km carry records for Grey-breasted Martin in and around Chapada dos Veadeiros National Park, and the 441 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.
The Osa Peninsula, Corcovado and Arenal are among the six atlas places where the Grey-breasted Martin is recorded. Its records concentrate in Panama, Costa Rica and Argentina, though the atlas also holds records from Brazil and Belize. This map follows where about 254,000 open records from 20 countries gather.
