Port Mansfield and the Lower Rio Grande Valley boast some 487 different species of birds.  This diverse variety makes ours one of the premier birding spots in the United States.  Many of these birds can be seen up close and very personal in and around the Port. Additional opportunities to view these beautiful birds in their natural setting are available via water. 

The Lower Rio Grande Valley has several major refuges and sanctuaries such as the Laguna Atascosa Wildlife Refuge, Santa Ana Wildlife Refuge, Bentsen State Park, Anzaldua Park Sal Del Rey (SALT LAKE), East Lake Tract, and Teniente Tract.
