Birding The Rio Grande Valley

he southernmost tip of Texas known as the Rio Grande Valley is one of the most popular birding and butterfly watching hotspots in the world. The four counties of Starr, Hidalgo, Willacy and Cameron form a subtropical coastal region with mild, dry winters and hot and humid summers. Inland, the drier landscape is dominated by thick spiny brush. The unique climate in South Texas attracts nature aficionados from all over the nation, especially for birding and butterfly watching. The majority of Texan birds, butterflies, dragonflies, amphibians, reptiles and mammals can be found in South Texas – making it a premier spot for nature parks and wildlife.The Rio Grande Valley also hosts eight annual nature festivals, as well as having many nature trails, viewing areas and events.

And for those with either too little mobility or too much sense to race around the woods with a tripod it is usually impossible. That's why I'm always so excited about our trip to the Rio Grande Valley in South Texas each April…
  • 2016 [01 January] - Chris Benesh

    ...It was a decent winter for rarities in the lower Rio Grande Valley, and we managed good views of a few of them. The best of the bunch was probably the Northern Jacana that performed well for us at Santa Ana National Wildlife Refuge. In addition, the female type Crimson-collared Grosbeak showed up, and while furtive, did sit still long enough to enjoy. Other rarities included a nice Tropical Parula. A couple of folks were able to add a Flame-colored Tanager to the rarities list, though it was uncooperative for the rest of us...
