Chestnut-sided Warbler
Setophaga pensylvanica
Arenal, Osa Peninsula and Manuel Antonio are among the six atlas places where the Chestnut-sided Warbler is recorded. Its records concentrate in the United States, Canada and Costa Rica, with further presence in Panama and Honduras. The atlas holds about 788,000 records of this bird from seven countries, and the map shows where these sightings gather most frequently.
Records are seasonal, peaking in May, August and September. They drop to their lowest levels from November through March.

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-sided 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.
