TROCHET, JOHN 1989 Masticophis bilineatus Sonoran Whipsnake Juckayou Wash, Willow Ranch, 35 miles W. of Seligman, Marjave Cr., Arizona. Elevation 4900 ft. August 26 Upon returning to my more easterly setting of nets, I noticed some "sticks" in one of the bird cages begin to move. These "sticks," in fact were the folded length of a long whipsnake judged to be this species by the marbled white labials, unspotted chin and clean pattern at the angle of the jaw. The striping along the side looked very clean, too. The snake's surprise reached the cage by climbing the small cottonwood bushes it was suspended. In order to escape, the snake regurgi-tated a not-quite-dead goldfinch, then released by coming at me through the wire mesh, mouth open, and sliding over my right shoulder onto the ground and gone in a moment. The animal appeared 4-4 1/2 feet long, total length. On inspecting the cage, I found another football-sized, leg-dead goldfinch, suggesting the snake had made an earlier kill one I did not notice at the time.
