What I consider the coastal bend of Texas runs from the mouth of the Guadalupe River to the North and South to the Corpus Christi area.  Bird watching in the coastal bend can be the best in the United States for numbers of species.  I regularly see over 100 species a day in the winter, and average 115-125 species in late April.  Here are some birds of interest in the coastal bend region that can be found.
