Thalasseus sandvicensis
Table Mountain National Park, Namib-Naukluft and West Coast National Park are among the five atlas places where the Sandwich Tern is recorded. Records concentrate most in the United States, United Kingdom, Spain, Portugal and France. The atlas holds about 436,000 open records of this bird from 29 countries, and the map shows where these records concentrate.
Because the Sandwich Tern is recorded in both the northern and southern hemispheres, recording seasons differ by region. Each place page in the atlas shows the months recorded there.
These are open occurrence records, so they show where people looked for and recorded the Sandwich 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.
