Crotophaga sulcirostris
Arenal, Tortuguero and Monteverde are among the four atlas places where the Groove-billed Ani is recorded. Its records concentrate in Costa Rica, Mexico, Belize, Honduras and Guatemala, with the atlas map following where these observations cluster. There are about 323,000 open records for this bird from 15 countries.
Recorded months differ by region, and the seasonal timing for each location is available on its respective place page.
These are open occurrence records, so they show where people looked for and recorded the Groove-billed Ani 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.
