Bird List
Welcome
The Rocky Mountain Arsenal National
Wildlife Refuge (NWR) is one of the
largest urban refuges in the country.
This Refuge provides important
feeding and resting grounds for
resident and migratory birds. The
Refuge was designated as a Colorado
State Important Bird Area by the
National Audubon Society in 2008.
When to Visit
The Refuge offers visitors unique
opportunities to view birds and other
wildlife. Dawn and dusk are the best
times of day to observe birds, and
spring and fall are the best seasons.
However, many birds are present
year-round on the Refuge. Colorful
songbirds pass through in the
spring. Shorebirds stop during their
migrations in spring and fall. In winter,
numerous bald eagles roost at the
Refuge and long-eared owls gather in
thickets. Waterfowl can be seen during
all seasons on the Refuge’s lakes.
About the List
This list of 273 birds follows the
organization of the American
Ornithologists’ Union’s Seventh
Edition Checklist, including changes
through the 55th Supplement.
The information contained in this
checklist is based on field data
collected between 1989 and 2014
by the Denver Audubon Society,
Denver Field Ornithologists,
Refuge staff and visiting birders.
Seasons
Since many birds are migratory, their
seasonal occurrence and relative
abundance are noted as follows:
