The Lower Rio Grande Valley National Wildlife Refuge is a 90,788-acre (367.41 km2)[2] National Wildlife Refuge located in southern Texas along the international border between the United States and Mexico.

Only 5% of the native landscape remains on the lower Rio Grande and its nearby reaches, yet the diversity within these fragments adds up to an astonishing 1,200 types of plants, 700 species of vertebrates (including nearly 500 bird species) and 300 kinds of butterflies. Eleven different biological communities exist on the refuge, from the Chihuahuan thorn forest to tidal wetlands.

Wildlife include the rare Ocelot, Northern Caracara, Mexican Bluewing Butterfly (Myscelia ethusa), Great Kiskadee, red-billed pigeon, Altamira oriole, ringed kingfisher and green jay.

The refuge is designated as part of the Great Texas Coastal Birding Trail, a network of wildlife viewing sites throughout the Texas coastal regions.[3]
