Heron before Dawn

I went out on the lake at 6am, about 25 minutes before dawn, and saw this bird at a point between two coves. I only got a few pictures of the heron before it flew off and these are the only two that weren't too blurred by the motion of my kayak and the dim light available.

The picture above was taken first, as I was approaching the point, and was taken at maximum zoom. The picture below I took about 2 minutes later while looking sideways at the heron. It was this motion, turning around in the kayak, that caused the bird to take off. Odd that he'd be afraid of people.
