Zimmerius parvus
Osa Peninsula, Tortuguero and Corcovado are among the six atlas places where the Mistletoe Tyrannulet is recorded. Records of this bird concentrate primarily in Costa Rica, Panama and Honduras, though it is recorded across seven countries in total. The atlas holds about 126,000 records for the species, and the map follows where these records gather most thickly.
Records of the Mistletoe Tyrannulet span the entire year, appearing in the atlas through every month.
Each bar is the share of its 165 month-dated grid cells with records in that month.
These are open occurrence records, so they show where people looked for and recorded the Mistletoe Tyrannulet 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.
