Piranga rubra
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 March, April, May, June, July, August, September, October and December, 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 Summer Tanager in and around Big Bend National Park, and the 6,380 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, Osa Peninsula and Monteverde are among the six atlas regions where the Summer Tanager is recorded. Records of this bird are most frequent in the United States, Costa Rica and Colombia, with the atlas holding about 762,000 records across 12 countries. Because its map tracks where these records concentrate, it reflects a partial view of the total range.
Of the 15 species with an atlas page recorded in and around Big Bend National Park, the Summer Tanager is the 3rd most recorded.
