U.S. Fish & Wildlife Service Tualatin River National Wildlife Refuge Watchable Wildlife Welcome to Tualatin River NWR Tualatin River National Wildlife Refuge means different things to different creatures. For some it's a place where they raise their young, and others just a stopover during migration. It's also a place that some only spend the winter, and to others, it is a year-round home. Established in 1992, the Refuge is located within the floodplain of the Tualatin River basin near Sherwood, Oregon. Refuge habitats are varied and include rivers and streams, seasonal and forested wetlands, riparian areas, grasslands, and forested uplands. An important breeding area for neotropical migratory songbirds, the Refuge also supports a significant breeding population of wood ducks and hooded mergansers. There is something to experience in every season. From thousands of waterfowl in the winter to breeding songbirds in summer, the Refuge is ever changing. Enjoying the Refuge's Wildlife We encourage you to explore the beauty of this area and stop, look, and listen to the abundant wildlife that call it home. The Refuge is a place where wildlife comes first so think of yourself as a visitor to their home. You will be a more successful wildlife observer if you: move slowly, talk softly, use binoculars, and leave only footprints behind. The wildlife species in this brochure have been grouped into four categories: birds, mammals, amphibians, and reptiles. Red-tailed hawks can be seen and heard soaring the open spaces over the Refuge Enjoying the Refuge's Birdlife Getting the Most from Your Visit Numbers and species of birds you will see here varies according to season, with the greatest numbers present from October to May. Heavy migrations of waterfowl occur during fall and winter. They come here to feed on wetland plants when their northern breeding grounds freeze over. Then, as water levels in the wetlands are drawn down in the spring, a wide variety of shorebirds are attracted to our invertebrate filled mudflats. When the wetlands dry out in spring and summer, songbirds arrive to breed and take shelter on the Refuge. Binoculars or spotting scopes are helpful for observing birds and a good field guide will help you identify what you see. You will see more birds if you time your visit for early morning or evening hours. Sit quietly and wait for the birds to come to you. When looking at a bird, pay close attention to characteristics such as color, size, shape, wing, and head markings. Always observe first and then refer to your identification book, because the bird may move out of sight quickly. This is especially true of perching birds. Also, be sure to listen for their calls and sounds. Take note of the type of habitat in which you see the bird, and where in the habitat they are likely to be found – canopy, tree trunk, brushy areas, open water, or ground area. You Can Help Seasons Sp - Spring, March through May S - Summer, June through August F - Fall, September through November W - Winter, December through February Seasonal Abundance Codes a - Abundant – species very numerous and easily seen or heard in suitable habitat. c - Common – species likely to be seen or heard in suitable habitat. u - Uncommon – usually present but may not be seen or heard in suitable habitat. o - Occasional – seen or heard only a few times a season in suitable habitat. r - Rare – may not be seen or heard every year in suitable habitat. Notes e t s b - Endangered Threatened Special of concern Breeding – confirmed or presumed to breed and/or nest on the Refuge. x - Accidental The following list of birds contains species that have been recorded on Tualatin River NWR. The common name and taxonomic order used in this list follows that appearing in the 7th edition of the American Ornithologist's Union Check List of North American Birds, published in 1998, and subsequent revisions. Since the establishment of the Refuge, the number of bird species seen here has quadrupled. We are still discovering species that are returning to the area. Keep notes – you may help us record the return of a species to the Tualatin River Valley!

It also reflects the change of an aquatic tadpole to a terrestrial adult frog or toad. In the spring and early summer look for them gathering in shallow ponds where they mate and lay eggs. Reptiles are egg laying animals that are protected by scales or horny plates. Look for them in grassy areas on the refuge. The exception are the turtles which are found near water.
