Glaucous-Winged Gulls, commonly known as Seagulls, are very often seen on the beaches around the North Shore (as well as widely across British Columbia). The plumage, or feathers, of the Glaucous-Winged Gull change as they get older. This can make it hard to differentiate between them and other gulls, as many species of gulls have similar colouring. Fish, shellfish, crabs, eggs are all common foods of the omnivorous Glaucous-Winged Gull – they will really eat anything they can find along the shoreline and coast! If you’ve ever eaten fish and chips on the beach, you might be familiar with Seagulls eyeing your meal and waiting for scraps. Glaucous-Winged Gull populations have grown tremendously over the past half-decade because of more populated urban environments leading to easier access to food.
