It is along the northern banks and reaches of the Lower Rio Grande , north of the Mexico—United States international border .
Ecology
Only 5% of the native riparian , floodplain , and wetland habitats remain along the lower Rio Grande and its local tributaries,[citation needed ] but the diversity within these fragments adds up to a significant 1,200 species of native plants , 700 species of vertebrates (including nearly 500 bird species), and 300 species of butterflies . Eleven different biological communities exist on the National Wildlife Refuge, from the Chihuahuan Desert thorn forest to tidal wetlands .[citation needed ]
Wildlife includes the rare ocelot , crested caracara , Mexican bluewing butterfly , 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]
Hunting permits are issued for native white-tailed deer , feral hogs, and introduced nilgai , which are a species of antelope native to India.[ 4]
