A Boutique Birding Festival

Come on down to Weslaco, Texas, the place to be in the spring for an excellent variety of wild birds, butterflies, and even dragonflies unlike anywhere else in the USA. The Lower Rio Grande Valley is home to many great birding sites, and Weslaco sits smack dab in the middle — certainly one of the valley's jewels. Small by city standards but situated near the banks of the Rio Grande, it supports a large array of birdlife found in few other places. With close proximity to both the Progreso and Donna International bridges, we're a destination that has something for everyone.

Whether you're a beginner or an experienced enthusiast, our premium field trip locations and exclusive access to private properties let you explore this renowned birding mecca for species such as Plain and Piebald Chachalacas, Green Jays, hummingbirds, and a number of Mexican seasonal migrants regularly found here — nothing short of extraordinary.

Why the Rio Grande Valley?

The Lower Rio Grande Valley is an ecological crossroads where subtropical, Gulf Coast, Great Plains, and Chihuahuan Desert habitats converge. Birds traveling the Central and Mississippi Flyways pass through during spring migration, making it one of the most diverse birding areas in the United States — the primary corridor for raptor and hawk migration each spring.
