Dead of unknown cause but no visible signs of external injury; on rock barren, 6cm SVL
18 basking, 1 swimming
Currently in communication with both Ontario Turtle Conservation Centre and Toronto Wildlife Centre to determine the best course of action. Currently it is in my care.
Update: Handed over to Toronto Wildlife Centre.
Frame grabs from a video. Need ID help - Cooper's? RS?. Bird was rather incompetently going after a squirrel, which seemed amused rather than afraid but was dodging feints by the bird.
