Bridget, too bad you can't get further south than Aransas WR. The area north
of Brownsville has Santa Anna NWR, Bentson SPand Falcon Dam SP with a number
of Mexican birds at their northern limit. The Brown and Green Jays, Audubon
and Altamira Oriole can be seen in Salino just south of Falcon Dam. Also the
Plain Chachalaca at Bentson.
