 Texas Birds in the Rio Grande Valley – Birding in South Texas

The counties of Starr, Hidalgo, Cameron and Willacy, also known as the Rio Grande Valley, make up the best Texas bird watching area in North America. There are more than 500 species of birds in Texas and the whole North America American Birding Association area has 914 bird species. The Rio Grande Valley has more than 50 native birds that are found nowhere else in the United States. Other birds pass through the area during seasonal migrations – all which make South Texas a hot spot for the richest and most diverse birding experience in the United States and Canada.

The area’s ecosystem is outstanding because of many factors, including the intersection of desert and tropical vegetation zones, the mix of ocean and fresh water resources, forest, bush, grassland, desert and sand dune, and its location under the confluence of the major eastern and central migration flyways.

The Rio Grande Valley has 80 great bird watching sites, with more being added each year; so birders from all over the world flock to this special area to enjoy birding and to fill their lists of Texas birds they’ve seen.
