The Rio Grande Valley of Texas stands alone as the premier destination for finding tropical bird species within the United States. With over 500 recorded species, the Valley represents a birding experience unlike anywhere else in the country.

 

This remarkable region, stretching from Falcon Lake east to the Gulf along the Rio Grande River, offers birders the unique opportunity to add dozens of specialty species to their life lists without leaving the country. This is an ecologically rich area where Chihuahuan Desert, subtropical Tamaulipan thorn forest, riparian woodlands, resacas, coastal marshes, and prairies all come together within a relatively compact area. A network of refuges, parks, and preserves provides excellent public access to observe the diverse array of birds and wildlife. Some notable birding locations include Santa Ana National Wildlife Refuge, Laguna Atascosa National Wildlife Refuge, Bentsen-Rio Grande Valley State Park, and Falcon State Park.

 

The Rio Grande Valley is renowned for hosting numerous species found nowhere else in the country. There are over two-dozen Valley specialties including among others:  Green Jay, Altamira Oriole, Muscovy Duck, Plain Chachalaca, Red-billed Pigeon, Great Kiskadee, Buff-bellied Hummingbird, Groove-billed Ani, and Hook-billed Kite. Birding the Valley is good year-round, but the period from fall migration through spring migration is when the most number of species can be found including resident species, migrants and wintering birds.

 

For many birders, a successful Valley trip represents a milestone achievement—a chance to add dozens of life birds while experiencing distinctive birding environments. Whether seeking specific target species, chasing rarities, or simply exploring one of North America’s most biodiverse regions, the Rio Grande Valley delivers memorable birding adventures.​
