Located four blocks from the Weslaco downtown business district, Frontera Audubon is a private non-profit nature preserve featuring mature native woodlands, thornscrub, trails, wetlands, and butterfly gardens.

This 15-acre urban site provides habitat for a wide variety of birds, butterflies, dragonflies, damselflies, and reptiles. Over 70 kinds of butterflies are documented on the nature preserve including many unique in the U.S. to South Texas.
Most of the Rio Grande specialty bird species are regularly seen here including the green jay (pictured below), buff-bellied hummingbird, great kiskadee, long-billed thrasher, green kingfisher, white-tipped dove, groove-billed ani, golden-fronted and ladder-backed woodpeckers, olive sparrow, black-crested titmouse (pictured to the right), and altamira oriole.
The Center is a model in land conservation, water management, and nature tourism. The staff is small in number but large in knowledge and hospitality.
The heart of the Sanctuary is the ‘Thicket’, “native Tamaulipan thornscrub, wetlands, and butterfly gardens” in the 15 acre property that is surprisingly in an urban section of town. It is a great place for novices to sit and watch birds come in to feeders, while rarities draw in experts and photographers to get close-up shots.
All of the trails in the Thicket are dirt trails but very well maintained and quite level with the exception of the elevated boardwalk over wetlands. There are a number of benches throughout the Thicket as well as seating set up at feeding stations.
Since there is a ramp accessing the visitor’s center, all of the Frontera Audubon Sanctuary except possibly the boardwalk is wheelchair and handicap accessible. There are clean restrooms inside the visitor center where maps of the trails are available as well as information about what birds, and butterflies, are being seen.

The ponds are fed by an artificial ‘stream’ that provides running water that is so attractive to birds as well as water drips to ensure the maximum species draw. There are benches across the sidewalk from the water feature where photographers are often seen getting close-up photos.
Thicket Trail
Frontera’s 15 acre site offers opportunities for bird and butterfly enthusiasts and all those interested in the wonders of nature and biodiversity.
Lesser goldfinches breed in the sunflowers behind the Visitors’ Center, and a wetland that has been developed on the property attracts large numbers of black-bellied whistling-ducks and shorebirds. Green parakeets have nested in cavities in the dead trees bordering the pond, and red-crowned parrots roost in old trees. Few places in the Valley are more populated with plain chachalacas. In migration the thicket is among the better spots to see neotropical migrants away from the coast.
