Are these Lesser Black Backed Gulls as well? Possibly the same 2 birds
not saying your wrong about the species. just thought id say this in case people could get moxed up by the lesser black backed gull with yellow legs. it is just cause of high exsposure or contrast that that the feet look yellow. there actualy pale. but thought this might be helpful
greater black backed gulls and herring gulls have pale legs. lesser Black backed gulls dont.
herring gulls have light gray blueish wings,
greater black backed has very dark grey wings
lesser black backed has yellow legs and gray wings. I hope this is helpful
lesser Black backed gull
