Vireo philadelphicus
Arenal, Manuel Antonio and the Osa Peninsula are among the five atlas places where the Philadelphia Vireo is recorded, with records gathering most thickly in the United States, Canada and Costa Rica. The atlas holds about 174,000 open records of this bird from eight countries. Because the range is partial, the map follows where these records concentrate, including locations in Honduras and Panama.
Observations are seasonal. Records peak in May before rising again from August through October, with low activity recorded during the remaining months of the year.
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 Philadelphia Vireo 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.
