An attractive fellow. The light was a little on the harsh side and well off to your right, but the HA towards you a bit did help make the best of that. Sharp, with nice catchlight. Perhaps a slightly lower shooting angle if the BG would allow. I might try to tone the whites a little.
Indranil, Beautiful feather details. I might tone down the whites as Randy suggested. Good sharpness and I don't have any images of Kildeer but am hoping to soon.
Thanks for all the feedback. This is the closest I have been to a killdeer! I took this from behind a tree close to the ground. The mudflats were further down, so this is the lowest I could go. Here is a repost with toned down whites...
