These little guys are hardly still for a second, as the name implies they constantly wag their tails and bob their heads up and down, this is a juvenile, all comments welcome
Nice bird, pose, and setting. I would crop at bottom to just above the small central rock and at right to eliminate about half the upright rock, and apply some NR to the BG. You may also want to eliminate the small light areas touching the bird's forehead and chest.
Beautifully sharp, lovely colors. Well done for a fidgety bird! Daniel hit my points about the crop and light spots, although if you take some off the bottom and right (which will help to get rid of some distracting rocks), you might also need to take just a tad off the top in my opinion. This will make a very handsome image even better.
