Buteo plagiatus
Drawn from open occurrence records in and around Big Bend 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 February, March, April, May, June, July, August, September and October, with the widest coverage in March, April, May, June, July and August. 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: 3 squares of 25 km carry records for Grey Hawk in and around Big Bend National Park, and the 2,923 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.
Arenal, Manuel Antonio and Monteverde are the three atlas places where the Grey Hawk is recorded, with records concentrating in the United States, Mexico, Costa Rica, Belize and Guatemala. The atlas holds about 293,000 records of this bird from eight countries, and the map follows where these records gather most thickly.
Of the 15 species with an atlas page recorded in and around Big Bend National Park, the Grey Hawk is the 5th most recorded.
