Turdus grayi
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 Clay-colored Thrush in and around Arenal, and the 68,563 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.
Osa Peninsula, Corcovado and Arenal are among the six atlas places where the Clay-colored Thrush is recorded. Its records concentrate in Costa Rica, Panama and Mexico, with about 900,000 open records across ten countries. This map tracks where those records gather most thickly.
Of the 193 species with an atlas page recorded in and around Arenal, the Clay-colored Thrush is the most recorded.
