I’ve seen one or two other photos of bitterns swimming but this is my first photo of this somewhat odd behavior. Why the bird didn’t fly to the other side of this narrow canal, I’m not sure. Possibly it figured flying might alert potential prey on the other side so he figured he would sneak on over. 🙂
Taken at Ridgefield NWR, Feb. 3, 2012, with my Canon 7d, 1/2000, f5.6, ISO640, Canon 400mm f5.6L lens.
