Some 800 miles wide the state of Texas is the largest of the lower 48 states. You go from East Texas pineywoods and bayous to open prairie, lakes, and oak trees. The Edwards Plateau comprises the Hill Country, south along the Gulf, into South Texas brush and the Rio Grande Valley-famous for birdwatching! Completing this diverse region is the Trans-Pecos and up into the Llano Estacado or staked Plains, the Panhandle. Most of the river systems run SE, like the Sabine, Angelina, Neeches, Trinity, Brazos, TX Colorado, Guadalupe, San Antonio, Nueces/Frio, the Pecos and Rio Grande. Going north you’ll cross the Canadian and the Red. The birding here is so rewarding due to the meeting of four bird flyways, migration routes: East, Mississippi, Mexican and Rocky Mountain species. I have visited Texas beginning in 2001, 2002, 2003, 2004 Gulf, 2005, 2006 and 2011, camping & birding over 20 state parks, and the Big Bend NP. Summers are very humid, but the rest of the year is just idyllic!
