Sternula albifrons
Drawn from open occurrence records in and around West Bali 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, 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 Little Tern in and around West Bali National Park, and the 415 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 and iSimangaliso Wetland Park are the two atlas places where the Little Tern is recorded. Its records concentrate in Taiwan, Australia, Spain, France and the United Kingdom, with about 195,000 open records mapped across 36 countries. This map follows where these records gather most thickly.
It is the only species with an atlas page recorded in and around West Bali National Park.
