bark-colored bird the size of your palm, jumps up from the narrow blacktop and sputters head-on into our pickup’s undercarriage. Lee Hoy, a wildlife guide with a long white beard and thick, black-framed glasses, is at the wheel, winding his truck along the dark road from Terlingua to Big Bend National Park in the early morning hours. Minutes earlier, Hoy had successfully avoided mowing one down. This time, he pumped the brakes and veered slightly, to no avail.
