Troglodytes aedon
Arenal and Monteverde are the two atlas places where the House Wren is recorded, with records gathering most thickly in the United States, Canada, Costa Rica, Colombia, and Mexico. The atlas holds about 2.5 million open records of the species across 15 countries. This map tracks where those records concentrate rather than the bird's entire range.
Recording months differ by region across the two hemispheres, and each individual place page shows the months recorded there.
These are open occurrence records, so they show where people looked for and recorded the House Wren 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.
