I like the look on his eye :)
I think it could benefit of a bit temperature rising and a vertical crop could work better from a compositional point, too much negative space. The heavy crop diluted some of the plumage detail.
Keep them coming.
I like your Heron Jeff. Considering the short lens you were working with that's a very clean shot. I would have to agree with Fabs, especially on the verticle format. Make sure if you do, crop from the left just a little and use the balance of space enough for him to look out of the picture. Nice job, pretty bird.
