Numenius phaeopus
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 Whimbrel in and around Sundarbans National Park, and the 1,926 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.
Arenal, Tortuguero and the Osa Peninsula are among the seven atlas places where the Whimbrel is recorded. Its records concentrate in the United States, Chile, Australia, Spain and Portugal. The atlas holds about 630,000 open records of this bird across 35 countries, and the map follows where these records gather most thickly.
Of the 9 species with an atlas page recorded in and around Sundarbans National Park, the Whimbrel is the 2nd most recorded.
