Chaetura vauxi
Drawn from open occurrence records in and around Olympic 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 May, 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: 5 squares of 25 km carry records for Vaux's Swift in and around Olympic National Park, and the 4,558 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 Vaux's Swift is recorded, with records concentrating in the United States, Costa Rica, Mexico, Canada and Guatemala. The atlas holds about 270,000 open records of this bird across ten countries, and its map shows where these records concentrate.
Of the 20 species with an atlas page recorded in and around Olympic National Park, the Vaux's Swift is the 10th most recorded.
