25. Mitchell Lake Audubon Center, San Antonio, Texas
Mudflats located just south of San Antonio teem with shorebirds and other migrants.
Published: August 24, 2007
|Mitchell Lake and its adjacent ponds and settling basins have a checkered history. Until 1973, they were sewage sludge ponds for San Antonio. Then the city declared the lake a refuge for birds and wildlife. San Antonio Audubon Society started regular birding trips around 1984.|
The history is part of what makes the lake such a great spot for birds. All of that biologically active input still fuels a food chain that provides a rich feast for local and migrating birds, including thousands of American White Pelicans in winter. Other wintering waterfowl include American Wigeon, Hooded Merganser, Eared Grebe, an occasional Cinnamon Teal, and large swirling rafts of feeding Northern Shovelers.
Even though the mudflats are more than 100 miles from the coast, they often teem with shorebirds during spring and fall migration. More than 25 species of herons, egrets, sandpipers, and plovers have been seen. Roseate Spoonbills are frequent visitors. And because the lake is located at the confluence of several migratory flyways, almost anything can show up. This past spring, a Swallow-tailed Kite put in an appearance, and we saw large kettles of Mississippi Kites and Broad-winged Hawks.
The summer breeding residents round out the seasons and include Groove-billed Ani, Least Grebe, Scissor-tailed Flycatcher, Painted Bunting, Orchard and Bullock's Orioles, and Black-necked Stilt. Barn Owls have also nested in the refuge. -- Eric Brierley
