A Birder's Eye View of the Seasons in the Lower Rio Grande Valley
Welcome to a birder’s eye view of the seasons in the Lower Rio Grande Valley. Enjoy our annual cycle! The resulting avifauna in deep South Texas is the most diverse north of the Mexican border. The four county area that makes up the lower Rio Grande Valley has recorded over 500 species of birds. This is more species of birds than have been recorded in all but two or three entire states. Small wonder that birders from across the continent make pilgrimages to the region. Happy Birding!
