Basileuterus delattrii
Arenal, Manuel Antonio and Monteverde are the three atlas places where the Chestnut-capped Warbler is recorded. Its records concentrate in Costa Rica, Colombia, Panama, Honduras and Nicaragua. The atlas holds about 130,000 open records for this bird from nine countries, and the map shows where these sightings gather most thickly.
Records of this member of the Parulidae family span the year, occurring through every month.
Each bar is the share of its 200 month-dated grid cells with records in that month.
These are open occurrence records, so they show where people looked for and recorded the Chestnut-capped Warbler 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.
