Gull x Herring(Vega)Gull?
Choshi, Chiba, Japan, April 7th 2001.
This individual looks like almost Glaucous Gull.
But the dark grey markings on primaries will be sign of hybrid.
|The general structure,
bill size, and wing projection
show obvious Glaucous-features unlike kumlieni.
Note the kumlieni -like wing-pattern. Another hybrid gull on the same day.
|The structure is very different from Iceland Gull (image below )|
