Amazilia tzacatl
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 Rufous-tailed Hummingbird in and around Arenal, and the 51,605 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 Rufous-tailed Hummingbird is recorded. Its records concentrate in ten countries, most frequently in Costa Rica, Colombia and Panama. The atlas holds about 690,000 open records of this bird, and the map shows where these sightings concentrate.
Of the 193 species with an atlas page recorded in and around Arenal, the Rufous-tailed Hummingbird is the 5th most recorded.
