Falco peregrinus
Drawn from open occurrence records in and around Grand Canyon 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 March, April, May, June, July, August, September, October, November and December, with the widest coverage in 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: 1 square of 25 km carry records for Peregrine Falcon in and around Grand Canyon National Park, and the 1,674 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.
Table Mountain National Park is among the areas where the Peregrine Falcon is recorded, with records concentrating in the United States, Canada, Belgium, Norway, and Taiwan. The atlas holds about 730,000 open records of this bird from 15 countries. Because the mapping is partial, the map indicates where these records concentrate rather than the full range of Falco peregrinus.
Of the 2 species with an atlas page recorded in and around Grand Canyon National Park, the Peregrine Falcon is the most recorded.
