By Tim, founder of Easy Street Markets. I maintain the wildlife database and verify every animal and source myself.

The states with the strongest confirmed populations are Alabama, Arizona, Arkansas, California, Colorado and Connecticut, and 39 more. These are real, verified iNaturalist and GBIF occurrence records, not modeled range estimates.
