Today we were to have our first full day on the Rio Grande. Sadly early in the day i developed migraine symptoms so missed the morning's birding as i slept with the help of pain killers.
The other lads visited the Sabal Palm Sanctuary.
Sabal Palm Sanctuary is one of the most distinctive natural areas in the Lower Rio Grande Valley, protecting a rare remnant of native sabal palm forest along the banks of the Rio Grande. Managed by the Gorgas Science Foundation, the sanctuary preserves habitat that has largely disappeared due to agriculture and development.
This unique ecosystem is dominated by Sabal mexicana, forming dense, humid groves that feel more like tropical Mexico than the United States. Beneath the palms, a rich understory of vines and shrubs supports a diverse array of wildlife. The sanctuary is particularly renowned among birders, offering opportunities to see Valley specialties such as Green Jay, Great Kiskadee, and migrating warblers.
A network of quiet trails and boardwalks winds through the forest, leading to scenic overlooks of the Rio Grande and adjacent wetlands. The site also includes a historic plantation house, adding cultural interest to the natural setting.
Sabal Palm Sanctuary plays a critical conservation role, safeguarding one of the last examples of this subtropical habitat in Texas. It serves as both a biodiversity refuge and an important destination for education, research, and ecotourism in the region.
In the afternoon I joined them for a visit to the Resaca de la Palma state park.
Resaca de la Palma State Park is one of the most significant protected natural areas in the Lower Rio Grande Valley, managed by the Texas Parks and Wildlife Department. Located just outside Brownsville, the park protects over 1,200 acres of native Tamaulipan thornscrub habitat centered around a historic resaca—an ancient oxbow of the Rio Grande.
The park is widely regarded as one of the premier birding sites in North America. Its rich mosaic of woodland, wetland, and scrub supports an exceptional diversity of wildlife, including specialty species such as Green Jay, Altamira Oriole, and Plain Chachalaca. The resaca itself provides critical water resources in an otherwise dry landscape, attracting birds, reptiles, and mammals year-round.
Unlike many state parks, access is primarily via a tram system, helping to minimize disturbance and preserve the integrity of the habitat. Visitors can explore a network of trails, observation decks, and hides that offer close encounters with wildlife.
Resaca de la Palma also plays an important conservation role, protecting one of the last large tracts of native vegetation in the region. It serves as both a refuge for biodiversity and a vital site for environmental education and ecotourism in south Texas.
