Phalacrocorax carbo
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 January, February, March, April, May, June, July, August, September and October, with the widest coverage in January, February, March, April, May, June, July, August, September and October. 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 Great Cormorant in and around Acadia National Park, and the 4,546 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.
Table Mountain and Addo Elephant National Parks are the two atlas places where the Great Cormorant is recorded. Its records concentrate in the United Kingdom, Norway, Belgium, Spain and France, with the atlas map following where these observations gather. There are about 1.4 million open records for this bird from 30 countries.
