South Texas offers some of the best birding opportunities in the United States. With its diversity of habitats including beaches, tidal flats, grasslands, brushlands and riparian woodlands, the area attracts hundreds of resident and migratory bird species throughout the year. For any birder, South Texas promises exciting discoveries and memorable sightings.
Introduction
South Texas extends from San Antonio south to the Rio Grande and the Mexican border, encompassing varied habitats from the Edwards Plateau and South Texas Plains eco-regions in the north through the Gulf Coastal Plains and on down to the semi-tropical Rio Grande Valley. This diversity of habitats gives South Texas an exceptionally high bird diversity with over 600 species recorded in the region.
Late winter and spring offer the most opportunities to see both resident and migratory species. In winter, ducks, geese, raptors and sparrows abound. And spring migration sees warblers, vireos, orioles and buntings passing through on their way north. But every season has its specialties here, both migrants and year-round residents. With some exploration and planning, birders of all levels can find great birding in every corner of South Texas.

The Best Times to Go Birding in South Texas
Though excellent birding can be found year round in South Texas, certain times of year offer the best opportunities to find both resident specialties and migrants. Here is an overview of the prime times to visit for birding:
Winter (December to February)
Winter is a great time to find ducks, geese, raptors and sparrows. Coastal sanctuaries like Aransas NWR will have large wintering flocks of ducks and geese, as well as visiting sandhill cranes. Rough-legged and ferruginous hawks, merlins, peregrine falcons and other raptors winter in the area’s open country. And sparrows abound in brushy areas, including wintering Harris’s, LeConte’s and Lincoln’s sparrows.
Spring Migration (March to May)
Spring is the absolute peak time for finding both resident birds breeding and multitudes of passage migrants. Aransas, Santa Ana NWR and other wooded areas will be dripping with brilliantly colored tropical warblers, vireos, buntings and orioles passing through. And South Texas specialties like green jay and great kiskadee can be found nesting. Shorebirds and inland waders peak in April and May.
Summer (June to August)
Though the heat can be intense, summer allows you to find South Texas specialties like plain chachalaca, white-tailed hawk and yellow-headed blackbird nesting and feeding young. Coastal sites are best for nesting colonies of seabirds like the endangered least tern. And migrant shorebirds begin returning as early as July.
Fall Migration (September to November)
Fall sees the return of many wintering species like sparrows, raptors and waterfowl. Migrating hawks can number in the thousands along coastal Peregrine Fund monitoring sites. And lingering tropical species can mix with arriving winter birds for a colorful transition season. October often sees rare stray migrants from the west show up along the coast as well.

Special Weather Events
Certain weather patterns can really concentrate birds and lead to rare sightings in South Texas. Here are some prime weather events to take advantage of:
Cold Fronts
The arrival of cold fronts in fall and spring can cause huge movements of migrating raptors and other birds along the coast. Hawks will kettle and head south in clouds, sometimes numbering thousands per day during peak migration at spots like Hazel Bazemore Park. Cold fronts also often deliver rare vagrant birds from further west or north.
Tropical Storms
Though the storms themselves are dangerous, tropical storms and hurricanes during summer and fall sometimes blow very rare seabirds like tropicbirds, magnificent frigatebirds and even puffins into coastal areas. Just after storms, birding can be spectacular.
Droughts or Dry Conditions
In years with lower rainfall, drought conditions can force unusual numbers of mountain and desert species like Montezuma quail, ferruginous pygmy-owl and phainopepla into South Texas habitats like brushlands and woodlands as they seek food and water resources.
Top Birding Events
There are a number of annual bird-focused festivals and events held across South Texas:
- Wings Over Winter – Based in the Rio Grande Valley every November, with guided birding tours, speakers and workshops.
- Great Texas Birding Classic – Held each April along the Upper Texas Coast, teams compete to identify species while fundraising for conservation.
