Vega Gulls Larus vegae
February 3rd 2007 Choshi Chiba Japan
A typical Vega Gull, mostly juveline plumege overall.
A darker individual, mostly juveline plumege.
A more advanced example. The mantle and upper scapulars have molted.
Probable 'taimyrensis'. Note the slimmer structure and dark outer greater coverts.
