Butorides virescens
Tortuguero is the atlas place where the Green Heron is recorded, and its records concentrate most in the United States, Canada, Mexico, Costa Rica, and Belize. The atlas holds about 1.2 million open records of the bird from ten countries, and the map follows where those records gather.
Records are seasonal, with a peak from April through 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 Green Heron 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.
