Ramphocaenus melanurus
Osa Peninsula, Corcovado and Arenal are among the five atlas places where the Long-billed Gnatwren is recorded. Its records concentrate in Costa Rica, Belize, Panama, Guatemala and Brazil, with the map following where these observations cluster. The atlas holds about 117,000 records of Ramphocaenus melanurus from 14 countries.
Recorded seasons for this bird differ by region, and each place page shows the months where it is documented there.
These are open occurrence records, so they show where people looked for and recorded the Long-billed Gnatwren 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.
