This Night-Heron seemed oblivious to our presence. We were in a boat in the Thames River (Ontario) and this Heron was hunting where a small creek emptied into the river. We approached as close as the water depth would allow, approx 40 feet from the bird, and the challenge was to get a shot clear of the obstructing vegetation. After about 20 frames, he slowly made his way deeper into the weeds. Shot at 500mm, cropped and adjusted in PS2.
