The colony of Yellow-legged Gulls on Tremiti islands is very numerous. When they first came to the island, seabirds such as shearwaters were breeding in crevices almost everywhere, but were completely replaced by the gulls, and were constrained to breed only in the vertical cliffs that the gulls don't like. Here is one recently fledged juvenile Yellow-legged Gull. A quite distinctive character for the species in this plumage is the black "mask" around the eye.
