Between October and March, visitors to the Refuges are likely to see as many as 27 species of ducks, including green-winged teal, gadwall, and mottled ducks. Huge flocks of snow geese, sometimes in excess of 80,000, feed in marshes, rice fields and moist soil units. During spring and fall, warblers and other songbirds can be found in small wooded areas, while shorebirds taking advantage of the sandy beach, mudflats and shallow water in moist soil units.  These wetland units provide excellent habitat for a variety of species. During winter months, large concentrations of waterfowl can be found feeding on native plants. In the spring and summer, the units may be flooded to provide habitat for nesting waterfowl, as well as for migrating shorebirds. Wading birds make use of these wetlands year-round. Wildlife in these moist soil units can be viewed from adjacent roads and overlooks.
