Pallas's or Great Black-Headed Gull's (Larus ichthyaetus) Feeding Preference for Toxic Lunartail Puffer (Lagocephalus lunaris)

More than any other group of seabirds, gulls exploit a wide variety of food types and have evolved highly diversified foraging methods and habitats. This has been demonstrated among gulls, both in the family as a whole and within each species, and at all times of the year. As a long-distance migrant, gulls, especially in the non-breeding season, spend more time on large water bodies along the coasts or in the open ocean; as a result they flourish on fish and marine invertebrates as their diet. Gulls in general are thus opportunistic and omnivorous.
