161. Estero Llano Grande State Park, Weslaco, Texas

Located just four miles north of the Rio Grande, a great place to find 30 South Texas specialties.

Just four miles due north of the Rio Grande lies one of the newest birding hotspots in South Texas: 230-acre Estero Llano Grande State Park. It opened in June 2006 after wildlife agencies and conservationists restored an old farm, a dried-up lakebed, and adjacent properties and made them accessible to visitors.

After less than seven years, the park’s bird list sits at 326 species, including migrants, wintering waterfowl, and about 30 specialty birds of South Texas — species not found anywhere else in the United States. I have spotted 316 species here, including a White-throated Thrush, the 13th ever in the U.S., and a Blue-throated Hummingbird, a Mexican bird rarely seen in Texas. I’ll never forget the incredible whiteness of a Whooping Crane I saw flying in a V-shaped flock of Sandhill Cranes in fall 2008.

An abundance of other wildlife lives here: almost 200 butterfly species, more than 60 dragonfly species, and resident alligators that live in the aptly named Alligator Lake. Next to the lake, two or three Common Pauraques often roost just off a trail, hiding in plain sight. Don’t miss them! — John Yochum
