My friend was walking and came upon this 4 ft Black Rat Snake coiled around a juvenile Broad-Wing Hawk. The Hawk was unconscious. He and his wife picked up the duo with a towel and untangled the snake. The snake had a small wound near the tail so he surmised that the hawk likely attacked the snake, but bit the wrong end. Big mistake! Rat Snakes are constrictors. The snake slithered away seemingly unaffected. The hawk took approx 20 minutes to recuperate and fly away. Happy ending for the snake - lesson learned we hope for the hawk.
The hawk had a purple band on its leg, but we don't know who tagged it.
A separate observation has been logged for the snake.
