I like it Gary, this is lake Martin, I might have met this bird before :)
I like the pose and the comp, and the sharpness in the face is good, the gray tree makes the browns stand out.
Running some NR on the BG would really help out here, the BG is a bit noisey.
Yes iso 2000 -it was 7:30 in the morning and if you know Lake Martin the sunrises behind those trees. My flash was in the car -far down the road. I'll correct the bg.
Must have been fun to find this one. He's a little dark, but you mentioned you didn't have your flash. The bright spot on the lower right is a bit distracting to me.
