Two hundred twelve bird species frequent Chatfield, either as permanent residents or migrators: the Chatfield Bird List is available for birdwatchers and can also be picked up at the park headquarters. The Bald Eagle, White Pelican and elusive Burrowing Owl may be observed either as migrants, winter, or summer residents.

Large areas of open space and the diversity of terrain and vegetation at Chatfield provide habitat for an abundance of wildlife. The park is in both Douglas and Jefferson counties.

The Denver Audubon is a Parks partner and has an office at Chatfield.
