U.S. Fish & Wildlife Service Rocky Mountain Arsenal National Wildlife Refuge 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: Sp S F W Seasonal Abundance: Other Codes Spring (March – May) Summer (June – August) Fall
