Actitis macularius
Drawn from open occurrence records in and around Acadia 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 Spotted Sandpiper in and around Acadia National Park, and the 4,251 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.
The Osa Peninsula and Corcovado are the two atlas places where the Spotted Sandpiper is recorded, with records gathering most thickly in the United States, Canada, Mexico, Costa Rica and Belize. The atlas holds about 1.1 million open records of this bird from eight countries, and its map follows where these records concentrate.
Of the 16 species with an atlas page recorded in and around Acadia National Park, the Spotted Sandpiper is the 7th most recorded.
