Piranga flava
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 April, May, June, July, August, September and October, with the widest coverage in April, May, June, July, August and September. 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 Red Tanager in and around Big Bend National Park, and the 2,270 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 and Monteverde are the two atlas places where the Red Tanager is recorded. Its records concentrate in the United States, Mexico, Costa Rica, Colombia, and Belize. The atlas holds about 181,000 open records of this bird from 19 countries, and the map shows where these records concentrate.
Of the 15 species with an atlas page recorded in and around Big Bend National Park, the Red Tanager is the 7th most recorded.
