A red-tailed hawk that was found in Newtown shot by an arrow has been released from a sanctuary for birds of prey.  The arrow was lodge through the hawk's leg and abdomen in mid-April.  He underwent surgery at South Wilton Veterinary Group and was taken to Weston-based Christine's Critters for rehabilitation. When the hawk was healthy enough for the bigger flight cage, he healed quickly.  He was released at a wildlife preserve on Great Hill Road.
