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
