Setophaga townsendi
Monteverde and Arenal are the two atlas parks where Townsend's Warbler is recorded, with records concentrating in the United States, Canada, Mexico, Guatemala, and Costa Rica. The atlas holds about 657,000 open records of this bird from six countries, and the map shows where these records concentrate.
Records of Setophaga townsendi span most of the year, although they are fewest during June and July.
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 Townsend's 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.
