Seagulls, also known as gulls, are seabirds that belong to the Laridae family. Their closest relatives are the terns even though they have some links to skimmers, auks, and waders.
The lifespan of seagulls depends on species but on average, seagulls live for 10-20 years. Large-white-headed gulls are known to be the most long-lived birds and can live for up to 29 years.
How long do seagulls live in the wild?
According to some experts, seagulls have a natural lifespan of about 20 years and there were many records of seagulls that have reached 25 years or even more. But, the unique behavior of these birds and their habits can sometimes cost their lives.
Namely, when seagulls live in the wild, it is not uncommon for them to be caught and eaten by other animals like foxes, weasels, sharks and cats. This is one of the reasons why their lifespan is so different.
There are many birds that don’t reach the age of 1 year while others live 25 years. It is good to mention that the first year of their life is critical. Most of the seagulls that pass the first year will experience natural death.
Finally, let’s not forget that different species of seagulls have a different life expectancy. Ring-billed seagulls usually leave between 12 and 15 years while herring seagulls can reach 30 or more.
How long do seagulls live in captivity?
Naturally, the seagulls that live in captivity have a longer life span. When they are kept in zoos and similar facilities they usually receive all the necessary care they need. This means that they are getting enough food and water and have enough space to exercise.
In addition, seagulls in captivity don’t have to worry about all the predators we have mentioned before. The young seagulls get extra care. On top of that, when they are in captivity they don’t have to deal with the consequences of extreme weather which are another thing that lowers their lifespan.

Seagulls reproduction and life cycle
Seagulls have one partner for life (they are monogamous birds). Breeding seagull pairs start courting late March and April. Early May is nest building. They lay a clutch of 3 eggs early May and hatch chicks in June. Seagulls are precocial, meaning that their chick hatch sighted, able to walk and downy.
The chicks are brooded by the male and female seagull for up to 2 weeks, where they grow bigger enough to start looking for small portions of food and return to the nest when the parent calls.
After this, the seagull develops contour feathers, starts exercising how to fly and eventually gain the strength and ability to fly far above the waters and forage it. It takes time for seagulls to master full foraging above the water.
Gulls are very social creatures. Once they establish a nesting roof, many seagulls move into that area. They become many in numbers till they establish a colony.
