Southern TX - Arizona Birding Guides

Laredo, Rio Grande City, Zapata

Birding Southern Texas

The Brush Country spans rolling thornscrub, cactus flats, and mesquite studded ranchlands between Laredo and Falcon Lake. This is true borderland birding, sunlit, rugged, and filled with species found nowhere else in the United States. The Rio Grande weaves through riparian forest and reservoir coves alive with flycatchers, doves, and hawks, while dense matorral shelters elusive quail and sparrows. Spring and summer bring song to every thicket, autumn concentrates migrants along river corridors, and winter fills open country with raptors and feeding flocks. With its mix of frontier landscapes, cultural flavor, and reliable rarities, the Brush Country delivers a uniquely South Texas experience that blends wild solitude with extraordinary bird diversity.
