Wildlife near Denver, Colorado
Denver runs up against the Front Range, and mountain wildlife spills down into the city. Mule deer and red foxes work the parks, black-billed magpies rattle from the cottonwoods, and Canada geese have taken over every pond and playing field. The South Platte River greenway carries herons, kingfishers, and the occasional beaver right through downtown, and raptors ride the thermals off the foothills all winter.

Most-observed species near Denver
Built from recent research-grade iNaturalist observations. Identifications are community-sourced and may occasionally be wrong, and the ranking reflects where people record and photograph wildlife, so a species seen often here is not necessarily rare elsewhere. Some plants and animals are only out in certain seasons. Treat this as a lively snapshot of what people are finding, not a formal checklist.
