Tringa incana
Drawn from open occurrence records in and around Channel Islands 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, July, August, September, October, November and December, with the widest coverage in April and August. 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: 4 squares of 25 km carry records for Wandering Tattler in and around Channel Islands National Park, and the 405 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, Osa Peninsula and Corcovado are among the three atlas places where the Wandering Tattler is recorded. Its records concentrate in the United States, Ecuador, Australia, the U.S. Outlying Islands and Canada. There are about 109,000 open records of this bird from 20 countries, and the map shows where these records gather.
Of the 10 species with an atlas page recorded in and around Channel Islands National Park, the Wandering Tattler is the 8th most recorded.
