Tigrisoma mexicanum
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 March, 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 Bare-throated Tiger-Heron in and around Tortuguero, and the 7,600 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, Corcovado and Arenal are among six atlas places where the Bare-throated Tiger-Heron is recorded. Its records concentrate in Costa Rica, Belize, Mexico, Guatemala and Honduras. The atlas holds about 123,000 open records of the bird from ten countries, and the map shows where these records concentrate.
Of the 102 species with an atlas page recorded in and around Tortuguero, the Bare-throated Tiger-Heron is the 2nd most recorded.
