Myiarchus tyrannulus
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 and August, 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 Brown-crested Flycatcher in and around Big Bend National Park, and the 1,466 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 parks where the Brown-crested Flycatcher is recorded, with records gathering most thickly in the United States, Mexico, Belize, Costa Rica and Guatemala. This atlas holds about 254,000 open records of the bird from 14 countries, and the map follows where these records concentrate.
Of the 15 species with an atlas page recorded in and around Big Bend National Park, the Brown-crested Flycatcher is the 9th most recorded.
