Geothlypis formosa
Drawn from open occurrence records in and around Shenandoah 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 and July, with the widest coverage in April, May, June and July. 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 Kentucky Warbler in and around Shenandoah National Park, and the 1,251 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 Kentucky Warbler is recorded, with records concentrating in the United States, Belize, Guatemala, Costa Rica and Honduras. The atlas holds about 152,000 records of Geothlypis formosa from nine countries. Because the map follows where these records concentrate, it represents a partial view of the bird's range.
Of the 9 species with an atlas page recorded in and around Shenandoah National Park, the Kentucky Warbler is the 9th most recorded.
