Least Sand pic taken at 0930 hrs showed a split in its supercilium, also a very marked breast streaking as opposed to the pics taken at 1030 hrs in the same place. This birds supercilium reaches the bill base and the breast streaking appears fainter. Is the first bird a Juv and the second a first winter !!!!!!!!!!!
