I think this might be American Herring Gull.

These featurs appear: nearly all dark tail, looking brown rump, solid dark neck and largely dark greater coverts.
Could it be a American Herring Gull?

Hi. I'm no gull expert, but it does look like a 2nd winter - overall, a dark brown colour, nearly all black tail, densely barred rump/vent/tail coverts. I'm sure the gull experts will be along soon with their views/opinions.

id go for slaty backed gull, some the moulting scapulars look dark grey and the primary wing flash is not pale enough for the herring complex

I'ts a fairly typical 2nd cycle Slaty-backed Gull. Pot bellied, smudgy head markings, plain greater coverts and tertials with smooth and broad white crescents.
