Distant looks, thru heat-waves, at an unusual white Sandhill'ish Crane.  This bird was amongst the large Sandhill Crane flock at Paul's Lake, Muleshoe NWR on 9 January 2003.   It had the size, shape and red cap of a Sandhill Crane, but it had the pure white body with black primaries of a Whooping Crane.  Perhaps this was a hybrid Whooping X Sandhill.
