Piranga rubra
Arenal, Osa Peninsula and Monteverde are among the six atlas regions where the Summer Tanager is recorded. Records of this bird are most frequent in the United States, Costa Rica and Colombia, with the atlas holding about 762,000 records across 12 countries. Because its map tracks where these records concentrate, it reflects a partial view of the total range.
Records follow a seasonal pattern. They peak during the months of April and May, as well as September and October.
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 Summer Tanager 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.
