Abstract

On 5 September 2008 at 0928 H, I observed an approximately 1.6-m (total length) gopher snake ( Pituophis catenifer ) constricting an adult Red-tailed Hawk ( Buteo jamaicensis ) on the side of Forest Road 10 in the Cibola National Forest near Magdalena, New Mexico, U.S.A. (34°10.38'N, 107°25.05'W), at an elevation of 2265 m asl. After approaching the snake, I noticed that the hawk was still alive but struggling to breathe, as it was immobilized by the snake (Fig. 1). The snake had coils around the throat, chest, and wings of the hawk. The Red-tailed Hawk did not have the gopher snake grasped in its talons or in its bill, and the snake did not have any visible external injuries. When I approached, the snake exhibited typical defensive behavior, including hissing and striking toward me (Sweet 1985, Young et al. 1995). Approximately 12 min (0940 H) after I began my observation, the snake released the hawk, perhaps due to my close proximity. Now released, the hawk quickly stood up, spread its wings, and stood back about 2 m from the snake for approximately 30 sec. It then flew into a dead tree 10 m away, where it rested for 2 min, before it flew off the side of the hill and out of view. The snake moved off the road into a thicket of juniper trees ( Juniperus monosperma ) as soon as the hawk flew into the dead tree.
