Vega Gull

Larus vegae

The Vega gull is similar to the herring gull but is slightly darker grey above. The head of the Vega gull is heavily streaked with brown in winter, especially on the back and sides of the neck forming a collar. The legs are usually bright pink. First- and second-winter Vega gulls are darker than the similar Mongolian gull, notably on the crown of the head where Mongolian gulls even in first- and second-winter are a bit paler. Almost the full body of first- and second-winter Vega gulls displays darker brown flecks and streaks.
