Steve, great DOF, good pose and HA, and I like the detail and colours in this. I would maybe lighten the eye a tad, and although not distracting, I would make an attempt to remove the grass through his tail.
A nice sharp bird with a good pose. Good comp and I like the way the bird is located in a little opening in the habitat. I'm OK with the habitat in this image except that I would wish that the one grass stem in front of the tail wasn't there. :)
