Basileuterus culicivorus
Drawn from open occurrence records in and around Iguaçu 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: 4 squares of 25 km carry records for Golden-crowned Warbler in and around Iguaçu National Park, and the 9,671 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 and Monteverde are the two atlas parks where the Golden-crowned Warbler is recorded, with records concentrating in Brazil, Costa Rica, Argentina, Colombia and Mexico. The atlas holds about 189,000 open records of this bird from 15 countries. The map shows where these records concentrate rather than the full range of the species.
Of the 56 species with an atlas page recorded in and around Iguaçu National Park, the Golden-crowned Warbler is the 4th most recorded.
