Wildlife near Denver, Colorado

Illustrated wildlife of Denver

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.
