U.S. Fish & Wildlife Service Ridgefield National Wildlife Refuge Wildlife Checklist “I slept but very little last night for the noise kept up during the whole of the night by the swans, geese...brant (and) ducks on a small sand island... they were immensley numerous and their noise horrid.” Capt. William Clark Lewis and Clark Journal Lower Columbia River November 5, 1805 The Pacific Flyway Welcome to Ridgefield National Wildlife Refuge Cover photo cackling Canada geese © Jim Cruce Ridgefield National Wildlife Refuge, located on the lower Columbia River floodplain adjacent to Ridgefield, Washington, provides 5,150 acres of vital migration and wintering habitat for birds migrating through the region west of the Cascade Mountains in the Pacific Flyway. The mild, rainy winter climate, combined with important remnant wetlands along the Columbia River, create ideal resting and feeding areas for a variety of species, including ducks, geese, swans, sandhill cranes and provides a key wintering area for the dusky subspecies of Canada goose. A variety of other wildlife also lives in the diversity of habitats found on the refuge. Birds of Ridgefield National Wildlife Refuge The grassland and wetland habitats of Ridgefield National Wildlife Refuge are best known for the spectacular concentrations of migratory waterfowl they attract during the winter. Seven subspecies of Canada geese occur here. Both trumpeter and tundra swans return every winter accompanied by their gray colored immature offspring. In late winter, shorebirds flock together in search of food hiding in the mudflats. Early spring brings the passerines and songbirds. Bald eagles nest here and are often seen causing a ruckus among ducks and other potential prey. Other nesting birds include herons, owls, some species of ducks, songbirds and sparrows. The Oaks to Wetlands Trail of the Carty Unit passes through Oregon white oak and Douglas fir forests, lush understory vegetation and by numerous wetlands and meadows. A Chinook Indian village originating in ancient times once existed here. The people hunted the elk, deer and birds that roamed the land. Lewis and Clark visited the village, camped here and described this place and its people. The Carty Unit exists today as it did then. It is not protected by flood dikes, thus water levels are dependent upon the rise and fall of the Columbia River. Expect more water during the spring snowmelt and during winter rains. Wildlife Watching Tips You will be most successful at viewing wild animals in their natural habitats if you use binoculars or a spotting scope. This equipment will help you observe wildlife from a distance and minimize disturbance. Wild animals, especially waterfowl are easily disturbed by humans and may be forced to use vital energy reserves trying to escape from their feeding and roosting areas. For this reason, be aware of special refuge seasonal regulations on public use activities during the fall and winter seasons. Wildlife watching is best shortly after sunrise and close to sunset. This will enhance your chances of seeing both nighttime and daytime active animals. Unusual Sightings? If you see any unusual sighting such as a species observed out of its normal season, in large numbers, or a new species not listed, please report your information to the refuge biologist at the address and phone number listed on the back cover of this leaflet. This information is greatly appreciated and will aid in future updates to this list. In addition it will provide the biologist with information about species occurances and populations on the refuge. Ridgefield is truly an amazing showcase of birds of the Pacific Flyway. Birding experiences vary upon the season of the year as you will see by the list that follows. We hope you will enjoy the birds and your visit!

Ridgefield National Wildlife Refuge This list includes 23 species of mammals which have been verified through biological surveys to occur within Ridgefield National Wildlife Refuge. The remaining 16 are potential species obtained from various publications. The numerous fresh water ponds and marshes of the refuge produce a variety of emergent aquatic vegetation and are usually bordered by riparian areas. These habitats attract all species of wildlife and are especially critical to the survival of many of these mammalian species. Although their preferred habitat is present, viewing mammals is not always easy to do. Mammals have very keen senses and are usually aware of visitors long before they are seen. This gives them warning to hide or use their camoflauging. Some are only active at night. Although they may not be seen, it is not hard to spot evidence of their presence such as fresh coyote tracks in the mud or a burrow hole leading to a rabbit’s warm nest underground. Look for the signs and have patience.
