Contopus cooperi
Drawn from open occurrence records in and around Rocky Mountain 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 May, June, July, August and September, with the widest coverage in 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: 1 square of 25 km carry records for Olive-sided Flycatcher in and around Rocky Mountain National Park, and the 830 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 Olive-sided Flycatcher is recorded, with records concentrating in the United States, Canada, Costa Rica, Colombia, and Ecuador. The atlas holds about 198,000 records of this bird from ten countries, and the map shows where these records gather.
Of the 5 species with an atlas page recorded in and around Rocky Mountain National Park, the Olive-sided Flycatcher is the 5th most recorded.
