Whilst the herring gull is by far the most numerous gull species in the Sidmouth area it is not the only gull seen here. In amongst them you can find the occasional great black-backed gull. Often seen in the company of herring gulls they seem to be less keen on the company of other great black-backs and are usually seen on their own or, more often perhaps, in pairs.
They are by far the biggest of the gull species we get here and have, as their name implies (which is not always a good guide!) a very dark or 'black' back. The only possible confusion would be with the lesser black-backed gull which is smaller (the size of a herring gull) and not having such a dark back. They are also far less common and are likely to be rare visitors to the area.
The great black-backed gull is a ferocious predator, having the advantage of size over its competitors, and readily takes chicks of other gulls, terns and waders. They are also great 'muggers' watching the other gulls around them and if they see one with food will attack and chase it until it drops the food and then swoops down to claim its prize.
Their big wing span makes them superb gliders and it is wonderful to see them out at sea looking for all the world like an albatross.
I'm such a fun! Your photos are great!
