Brownsville’s Resaca de la Palma boasts the largest tract of native habitat in the World Birding Center network. Etched by ancient curves of the Rio Grande, its 1200 semi-tropical acres provide a quiet retreat from the hustle and bustle of an international urban center only a few miles away. Through the cooperation of local & federal land management agencies, a wilderness preserved from days gone by is open to nature adventurers for the first time.
