Nice perch, pose, and BG. Pointing your lens a bit more to the left (and maybe also down a bit) would have strenghten the comp IMO. Those whites can sure be tough...
Kingfisher stands out nicely from the background. I am not a fan of that contrasty and busy background. I wonder what a vertical crop on the kingfisher would look like -- it would de-emphasize the background some.
Really like the composition Michael and the wonderful BG. The whites are tough but you did well to capture this elusive bird out in the open. Congratulations.
