Top Birding Hotspots in the Rio Grande Valley
The Rio Grande Valley of South Texas — spanning Starr, Hidalgo, Cameron, and Willacy counties — is home to some of the most productive birding locations in North America. World Birding Center sites, national wildlife refuges, and local nature parks across the four-county region regularly produce RGV specialty birds like Green Jay, Altamira Oriole, and Hook-billed Kite, alongside seasonal migration fallouts and rare vagrants that draw birders from across the continent.
