The natural lifespan of a seagull is 20 years or more. However, since seagulls live in the wild, they can be eaten by predators such as weasels, foxes, cats or sharks.
There are over 20 species of seagulls that live all over the planet; although they are sea birds, they can be found in areas far away from water. Seagulls have existed for around 30 to 33 million years. They are intelligent birds that can work together in groups, investigate, learn and generalize. They begin breeding when they are between three and seven years old, and can be territorial and aggressive when protecting their young.
