Birding In Sierra County, Pt. 3
Fifteen minutes south of Elephant Butte Lake is Caballo Lake, the best site for gulls in the entire state. Thirteen of the state's 15 species are seen here. Percha Dam State Park, with its extensive stands of cottonwoods along the Rio Grande, make the park a haven for migrating birds. It's considered to be the state's best birding site.
