Description: SWAN LAKE: View from US 91 only. The best way to bird this site is to park in the small gravel pull-out which provides a good view. Swan Lake usually thaws in March making spring migration-a great time to see shorebirds and thousands of waterfowl including Tundra Swan (also hundreds in fall) and Northern Pintail. The wetland is good for nesting Sora, Virginia Rail, and Marsh Wren. Watch for nesting Sandhill Crane and for White-faced Ibis flying over the marsh during the breeding season. Watch also for Peregrine Falcon, Golden Eagle, Red-tailed Hawk, Short-eared Owl, and Northern Harrier during spring and summer, and Bald Eagle in winter. TWIN LAKES RESERVOIR: Surrounded by cottonwood trees with sagebrush hills behind them, Twin Lakes Reservoir is best explored by bike or by car. Up to 150 Common Loon during spring migration (especially April). Other common migrants include Western and Eared Grebes, and many diving ducks. Check cottonwood trees for nesting Bullock’s Oriole.
