Egretta caerulea
Osa Peninsula, Tortuguero and Arenal are among the five atlas places where the Little Blue Heron is recorded. Records of Egretta caerulea concentrate most heavily in the United States, Costa Rica, Mexico, Belize and Panama. This atlas holds about 1.3 million records from 12 countries, and the map follows where these records concentrate.
Recording seasons differ by region, and each place page shows the months recorded there.
These are open occurrence records, so they show where people looked for and recorded the Little Blue 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.
