Kaw Lake is the winter home to one of the largest concentrations of Bald Eagles in the state. Many birds can be found perched on large trees by the lake or below the dam. The lake also has large flocks of waterfowl and gulls each winter. Smith's is the most common longspur with large flocks of Lapland Longspurs also occurring. McCown's and Chestnut-collared are found occasionally as well.
Sooner Lake is a classic prairie reservoir which harbors abundant waterfowl and prairie birds.
Peak activity is usually reached in the fall and early winter with almost all of the regularly occurring waterfowl arriving for the winter, including Greater Scaup. Tundra swan, Oldsquaw, and Pacific Loon are rare but regular visitors. The large flocks of Canada Geese often include a handful of White-fronted and Snow Geese. In migration, enormous flocks of Franklin's Gulls are found on the center of the lake. All of the other three longspurs have occurred but are rare.
