The Rio Grande Valley is home to the World Birding Center and has several locations throughout the Valley. Weslaco features one location, Estero Llano Grande State Park, and a nature center located in the middle of downtown, Frontera Audubon.
Estero Llano Grande State Park is the geographic center of the World Birding Center network. The park attracts a spectacular array of South Texas wildlife with its varied landscape of shallow lake, woodlands and thorn forest. Visitors will enjoy exploring the 230 plus-acre refuge.
Water is the magic ingredient for attracting wildlife and the park offers the largest wetlands environment in the World Birding Center network. A shallow lake, fringed with marsh cane, is actually part of the Arroyo Colorado. Classic Rio Grande woodlands add variety to the park that already boasts a well-deserved birding reputation. A former agriculture field was transformed in wetlands, with an island just right for a secure nesting site.
