Melanerpes formicivorus
Drawn from open occurrence records in and around Yosemite 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 January, February, March, April, May, June, July, August, September, October, November and December. 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: 3 squares of 25 km carry records for Acorn Woodpecker in and around Yosemite National Park, and the 11,964 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.
Manuel Antonio is the atlas park where the Acorn Woodpecker is recorded, and its records concentrate in the United States, Colombia and Costa Rica, followed by Belize and Guatemala. The atlas holds about 1.4 million open records of the bird from eight countries. This map shows where those records concentrate.
Of the 5 species with an atlas page recorded in and around Yosemite National Park, the Acorn Woodpecker is the most recorded.
