Sandhill Cranes in the San Luis Valley

Anyone who has ever birded Colorado's San Luis Valley knows how special it can be when you get to watch raptors or Sandhill Cranes flying with the Sangre de Christo Mountains as a backdrop as the middle pic shows. I enjoyed a few hours of birding there yesterday including a flock of about a hundred Sandhill Cranes including those in these pics, first of the year Great Egret, Snowy Egret, American Avocet, several male Yellow-headed Blackbirds and 2 probable White-faced Ibis.
