Haematopus palliatus
Corcovado and the Osa Peninsula are the two atlas parks where the American Oystercatcher is recorded, with records concentrating in the United States, Chile, Peru, Argentina and Uruguay. The atlas holds about 550,000 open records of this bird from 14 countries, and the map shows where these records concentrate.
Seasons for the American Oystercatcher differ by region, and each place page shows the months recorded there.
These are open occurrence records, so they show where people looked for and recorded the American Oystercatcher 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.
