An adult Gull (Herring or Yellow-legged Gull)


An adult Gull in breeding plumage. Naturally, in early April in Finland it should be an argentatus, but is it?
Nevertheless, a Gull resembling this is here.

The longcall was lower and hoarse compared to song of an average adult argentatus. 12.4.2008 Tara dump. Foto: Hannu Koskinen


Plenty of black in 6 outer primaries. Pattern of outer primaries confirms, that this bird is the same as this.

Intensive yellow in bare parts. Note also clear red eye-ring, moustache and a hint of reddish from gonys reaching the upper mandible.

Primary tips are already worn, and the amount of white in tips are reduced compared to an average argentatus with yellow legs.
Compare with these yellow-legged Herring Gulls on the same day.
