Buteogallus anthracinus
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 March, April, May, June, August, September and October, with the widest coverage in March, April, May, June, August, September and October. 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 Common Black Hawk in and around Zion National Park, and the 177 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.
The Osa Peninsula, Corcovado and Tortuguero are among six atlas places where the Common Black Hawk is recorded. Records concentrate most in Costa Rica, the United States and Mexico, though they also gather in Panama and Belize. The atlas holds about 139,000 open records from 14 countries, and the map follows where these records concentrate.
Of the 5 species with an atlas page recorded in and around Zion National Park, the Common Black Hawk is the 4th most recorded.
