Good clear reflections always draw my eyes to an image. I like how the beak is just away from the water, as if he's about to peck at something. Exposure looks good on a difficult character, and overall nice and sharp.
Fine execution of a beautiful bird - captures the delicate, elegant nature of the bird very well with this pose - although I presume the American variety is just as noisy and aggressive as our European Pied Avocet.
Beautiful capture in pixels ,avocets reflection is just about a perfect mirror image ,and the soft muted colours add a little something mystical to the whole image
