Diet & Feeding Habits

The great black-backed gull is a voracious eater, capable of consuming up to 50% of its body weight in a single day. It has an incredibly varied diet, consisting mostly of insects, fish, crustaceans, mollusks and other invertebrates. They are also known to consume eggs and chicks from other bird species. The great black-backed gull will often scavenge for food alongside other birds at landfill sites or fishing boats.

In addition to these sources, they have also been observed eating fruits and seeds when they are available. They have even been known to steal food from other animals such as rabbits and rodents. This type of behavior is known as kleptoparasitism. Interestingly enough, the great black-backed gull can be seen hunting cooperatively with other birds in order to increase their chances of success in capturing prey.

The next section will explore the breeding habits and nesting behavior of the great black-backed gull. As one might expect from such a successful predator, their breeding and nesting strategies are just as impressive as their feeding habits.

Breeding & Nesting

Great black-backed gulls breed in large colonies near coastlines, typically on rocky islands. They construct a simple nest using grasses, seaweed and other debris collected from the shoreline. The female lays two to three eggs at a time and both parents share incubation duties for about four weeks. After hatching, the chicks are tended to by both parents for about five weeks until they fledge.

The juveniles stay close to their parents for another six months, after which they disperse and become fully independent. This species has an average lifespan of 15 years in the wild, but can reach up to 30 years old in captivity. With next section transition: Physical attributes of the great black-backed gull include its large size and powerful wingspan, which make it well adapted for long distance flight and coastal living.
