Six kinds of gull (Larus spp) can be commonly seen in Liverpool Bay, these are; Common gull, Herring gull, Mediterranean gull, Black-headed gull and the Lesser and Great black-backed gulls.
The common and herring gull look very similar, but common gulls are somewhat smaller in size with a smaller beak. The lesser and great black-backed gulls also look extremely similar, but the latter can be identified by its larger size, darker back and paler, pinker legs. The black-headed gull is one of the smaller members of the gull family, identifiable by its reddish-coloured legs. Its dark-brown (as opposed to black) head becomes a white colour during winter, with a dark spot remaining near the eye. The Mediterranean gull is slightly larger than the black-headed gull, and has a completely black head, red legs and a reddish bill with dark markings near the tip in most individuals.
The gulls weight can range from 300g (common gull) through to a whopping 2.3kg (great black-backed gull), with a wing-span ranging from 86cm (black-headed gull) to 1.67m (great black-backed gull).
IUCN status Least Concern
Where to find them:
These gulls are all common species in Liverpool Bay, with no lack of abundance around the coastline.
Gulls will eat a wide range of foods, but their diet mainly consists of small fish and invertebrates such as worms.
Did you know gulls have long, slim wings which are incredibly strong?
