Sierra County is one of the finest birding regions in the nation in terms of habitat diversity and potential for rarities. The riparian habitat along the Rio Grande and its associated lakes is a paradise of egrets, herons, pelicans, grebes, and unusual avian sightings, and all three of Sierra County’s state parks(Percha Dam, Caballo and Elephant Butte) were recently designated by the Audubon Society as important birding areas.
In the spring, Percha Dam State Park, considered to be New Mexico’s best area for land birds along the Rio Grande, hosts “Migration Sensation” – two days of birding and bird-related programming. Each day begins with guided bird walks to observe sparrows and other birds passing through during the spring migration.
