Quiscalus mexicanus
Arenal, Monteverde and Manuel Antonio are among the four atlas places where the Great-tailed Grackle is recorded. Its records concentrate in the United States, Mexico, Costa Rica, Guatemala and Belize. The atlas holds about 2.2 million open records of this bird from ten countries, and the map shows where these records concentrate.
Records of Quiscalus mexicanus are available year-round, spanning every month of the calendar.
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 Great-tailed Grackle 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.
