Sternula albifrons
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.
Because this bird is recorded across both hemispheres, the active months differ by region. Each place page in the atlas shows the particular months it is recorded there.
These are open occurrence records, so they show where people looked for and recorded the Little Tern as much as where it lives. The atlas keeps a species' 200 best-recorded grid cells, so the map shows where records concentrate rather than its whole range. Cells are up to 25 km across, and every location is generalised to its cell.
Generalised encounter areas, not exact locations. Each shape is a grid cell coloured by how likely the species is there.
Conservation status not assessed here yet, so every location is generalised to its grid cell.
