Birds landing in a marsh

Decreasing water levels typical during summer creates mudflats that attract a diversity of shorebirds during the fall migration. The fall migration peaks in late July and early August attracting many shorebirds, such as American avocets, killdeer, Wilson’s phalaropes, willets, marbled godwits, upland and spotted sandpipers.
