The gulls feed on insects, mollusks, crustaceans, and worms and grubs in cultivated fields along the seashore, and they also feed on small shoreline fish, and scavenge for leftovers discarded along the shoreline and from boats. Some large gulls prey on the eggs and chicks of other birds, including their own kind. Gulls prefer to flock to areas of the sea where food is plentiful. So wherever large flocks of gulls are found, the waters are teeming with life. The blue sea is full of fish and the blue sky is full of gulls, making the rich ocean full of vitality.

Population status:

The species has a wide distribution range and is not close to the vulnerable endangered threshold criteria for species survival (distribution area or fluctuating range of less than 20,000 square kilometers, quality of habitat, size of population, and fragmentation of the distribution area), and the trend of the population size is stable, so it is evaluated as a species with no survival crisis.
