Numenius arquata
Drawn from open occurrence records in and around Sundarbans 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, July, August, September, October, November and December, with the widest coverage in January, February, March, April, 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: 1 square of 25 km carry records for Eurasian Curlew in and around Sundarbans National Park, and the 1,335 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.
West Coast National Park is the atlas place where the Eurasian Curlew is recorded, and its records gather most thickly in the United Kingdom, Norway, Belgium, France and the Netherlands. This map shows where records concentrate, drawing on about 647,000 open records from 27 countries.
Of the 9 species with an atlas page recorded in and around Sundarbans National Park, the Eurasian Curlew is the 4th most recorded.
