Seagulls drink water.

Gull food

Silver gulls are omnivorous birds. They often gather in flocks near ships and in landfills. On the ground they hunt lizards, small rodents, larvae and insects. Bred nests of other birds, eating their eggs and chicks. From plant foods, preference is given to nuts, grains, fruits, berries and tubers. Love sea worms and crustaceans.

Silver gulls fish fish at the water surface, while they immerse the upper body in water and look for prey. Seagulls even know how to dive, but not more than 1 meter. In weaker birds, these birds take prey.

Often they look out for a victim whirling above the water. If the prey has a protective shell, then the bird rises into the air, throws it on the stones and, thus, breaks it. Fish is not the basis of the diet of silver gulls, but during nesting, these birds try to catch as many fish as possible, since the chicks feed on it.

Reproduction and longevity

The silver gull eats not only animal, but also plant foods.

Silvery gulls are highly organized birds, a peculiar hierarchy with a complex structure of relationships is maintained in the flock. Males are considered leaders, and females must obey them. But when it comes to choosing a place for a nest, females dominate. Monogamous pairs build silvery seagulls, which, as a rule, last for life.

Feathered flies to nesting sites when ice begins to melt. In the northern regions, this does not happen until April-May. For the nesting period, silver gulls are combined into large colonies. Nests are built on the banks of cliffs, on rocks, and sometimes in thickets of vegetation. Between the nests, a distance of 3-5 meters is maintained. Females are built by females along with males. Natural materials are used for their construction: tree branches, moss and grass. The inside of the nest is insulated with feathers.

The female hatches 2-4 eggs, most often in the clutch there are 3 pieces. Both parents are involved in the process of hatching eggs, replacing each other. The incubation period takes 4 weeks. The body of newborn chicks is covered with gray down with dark spots. On the 2nd day of life, they begin to get up, and after 1.5 months they begin to fly. But for another month they remain with their parents, who alternately feed them.

During feeding, the chick beats with its beak on the red spot located above the beak of the parent, and he spits up food. Puberty in silver gulls occurs at 5 years. Life expectancy in the wild is on average 45-50 years.

A silver gull can live up to 50 years.

Relationship with man

Silver gulls are not afraid of people. They actively settle in megacities on the roofs of houses. If the seagull believes that a person wants to harm the offspring, she attacks him. Sometimes these arrogant birds snatch food from people on the street, right from their hands.

Over the past 25 years, there has been a tendency to reduce the number of silver gulls. In Europe, the number of these birds decreased by 50%. The main reason for this situation is environmental factors and a decrease in the number of fish in coastal areas. In connection with these events, European silver gulls are in the Red Book. Despite the fact that silver gulls have conservation status, it is not known whether this will help preserve the species.
