Tigrisoma mexicanum
Tortuguero, Corcovado and Arenal are among six atlas places where the Bare-throated Tiger-Heron is recorded. Its records concentrate in Costa Rica, Belize, Mexico, Guatemala and Honduras. The atlas holds about 123,000 open records of the bird from ten countries, and the map shows where these records concentrate.
Records of Tigrisoma mexicanum span every month 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 Bare-throated Tiger-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.
