Pygochelidon cyanoleuca
Arenal, Monteverde and Manuel Antonio are the three atlas places where the Blue-and-white Swallow is recorded, with records concentrating in Costa Rica, Brazil, Colombia, Ecuador and Peru. The atlas holds about 555,000 open records of this bird from 12 countries, and the map follows where these records concentrate. Because this species is recorded across both hemispheres, seasons 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 Blue-and-white Swallow 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.
