Cinclus mexicanus
Drawn from open occurrence records in and around Zion 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: 2 squares of 25 km carry records for American Dipper in and around Zion National Park, and the 2,905 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.
Monteverde and Arenal are the two atlas places where the American Dipper is recorded, and its records concentrate in the United States, Canada and Costa Rica. The atlas holds about 138,000 records of this bird across six countries, including Panama and Mexico. Because the range is partial, the map indicates where these records cluster.
Of the 5 species with an atlas page recorded in and around Zion National Park, the American Dipper is the 2nd most recorded.
