Fig 1) A typical adult in winter. Note the pale gray mantle with no strong tertial crescent-- an easy way to separate them from other species at long range. Photo courtesy of Don DesJardin.
Fig 2) This bird is already showing a bright orbital ring associated with breeding. February 16, 2013. Petaluma, California. Photo by Steve Hampton.
|Fig 4) This bird has more sparse head streaking. Again, not the lack of a clear tertial crescent. December 17, 2011. Davis, Calfornia. Photo courtesy of Steve Hampton.|
|Fig 5) A late winter adult, still with some head streaking. March 23, 2011. Clearlake, Calfornia. Photo courtesy of Steve Hampton.|
|Fig 6) This photo was taken the same day as the previous photo, only this bird is already in full breeding plumage. Note the vivid bare part colors: the red eye ring and bright bill and legs. Again, note the virtual lack of tertial and scapular crescents. March 23, 2011. Clearlake, Calfornia. Photo courtesy of Steve Hampton.|
