World Birding Center | Estero Llano Grande State Park (Weslaco, TX)

Our Birds
Estero Llano Grande has a well-deserved reputation as a can’t-miss birding destination. In late summer, when water is at a premium, hundreds of waders & shorebirds flock here, including the endangered Wood Stork, along with colorful coastal species like the Roseate Spoonbill and Ibis. Migrating waterfowl also make a beeline for the park’s narrow, shallow lake. Elsewhere, woodland & thorn scrub harbor all the must-see Valley specialties such as the Groove-billed Ani & Altamira Oriole. Adding spice to this mix, visitors may even spot rare Red-crowned Parrots and Green Parakeets.
