U.S. Fish & Wildlife Service Arapaho National Wildlife Refuge Wildlife List Home for Wildlife This goose, designed by J.N. “Ding” Darling, is the symbol of the National Wildlife Refuge System. Arapaho National Wildlife Refuge (NWR) is located in an intermountain glacial basin south of Walden, the county seat of Jackson County, Colorado. The Refuge was established in 1967 to provide migratory birds with a suitable place to nest and rear their young. It was created to offset, in part, losses of nesting habitat in the prairie wetland region of the Midwest. Arapaho NWR is one of over 550 refuges in the National Wildlife Refuge System - a network of lands set aside specifically for wildlife. Managed by the U.S. Fish and Wildlife Service, the Refuge System is a living heritage, preserving wildlife and habitat for people today and for generations to come. The Refuge provides excellent habitat for a variety of wildlife. The irrigated meadows are ideal for nesting waterfowl and other species of birds. Riparian areas offer excellent habitat for moose, elk, and neotropical birds. Upland game birds, neotropical birds, and pronghorn can be seen on the sagebrush flats and knolls. Waterfowl Through the Year The first waterfowl arrive at Arapaho NWR when the ice vanishes from the lakes and wetlands in late March to mid-April. Peak waterfowl migration occurs in late May when 5,000 or more ducks can be present. Canada geese, once scarce in the North Park area, have been re-established here. They begin nesting on the Refuge in April. Duck nesting usually starts in late May and peaks in mid-June. The Refuge produces about 8,000 ducklings and 300-400 goslings each year. Fall migration reaches its height in late September or early October when up to 8,000 waterfowl may be on the Refuge. Pronghorn / USFWS Wildlife Observation Opportunities A self-guided auto tour route on the Refuge offers visitors great opportunities to observe wildlife. A corresponding auto tour route leaflet provides wildlife, habitat, and Refuge management information related to stops along the route. More information about Arapaho NWR and recreational activities can be found at the Refuge headquarters. May through October are the best months for observing birds on the Refuge and in the surrounding North Park area. Most mammals can be observed year-round. About this Checklist The following table lists 208 species of birds, 37 mammals, and 16 other vertebrates that have been observed on the Refuge. Species of birds which have been known to nest on the Refuge are preceded by a bullet (●). Common names for mammals, fish, reptiles, and amphibians are followed by a specific abundance code (see codes below). Seasons of Occurrence: Since most birds are migratory, their seasonal occurrence and relative abundance are coded as follows: Sp S F W Spring (March-May) Summer (June-August) Fall (September-November) Winter (December-February) Seasonal a abundant, occurring in large Abundance: numbers c common, certain to be seen in suitable habitat u uncommon, present but not certain to be seen o occasional, seen only a few times during the season r rare, seen at intervals of 2 to 5 years x accidental, vagrant, or out of normal range Common Bird Name Sp S F Ducks, Geese, and Swans Snow Goose ● Canada Goose c c
