Waterfowl - Northern New Mexico

Waterfowl - 24 July 2008 - northeast of Cimarron, New Mexico. I think these are Avocets - but identifying birds is not a strong suit. This was the last picture of the day insofar as a huge thunderstorm came rumbling in from the west. Double Click on the image. Nikon F3HP w/500mm F:8.0 Tamron SP.
