Kevin, you have a great shot here although I think it does need to little work to bring out the best in it. The background, perch and throat of the bird all look too light for me. Bird's throat in particular is lacking detail and may be close to blowing. However, the back end of the bird in shadow wouldn't benefit from going any darker. So the trick is to play more with your white point to move it out a little and or darken highlights. An alternative is to drop the overall exposure but then you'd need to lighten shadows. These are global adjustments. It might be even better to make selective adjustments on the problem areas, particularly the throat and back end to bring more detail into those areas. Overall, clarity and detail look good to me.
As for composition, I feel there is too much at the bottom of the frame here. You could also consider a landscape crop but that is a personal preference of mine that many don't agree with.
