Many people come to Texas to see many of the "valley specialties" that can only be found in the Rio Grande Valley of Texas.  The valley runs from the Laguna Atascosa NWR to Brownsville and west to about San Ygnacio.  In this region, you will find many tropical species found nowhere else in the United States.  Here is a list of the birds of interest that are regularly found in the valley.  Every year many "accidentals" also occur in the valley, many that have only been found in the United States a few times.
