Yellow-legged Gull Larus michahellis Praia da Vitoria, Terceira Island, Azores, Portugal 15 July 2013 This species is common and widespread all across the island of Terceira. I have photos of all ages of these gulls but will just post adults or 3rd winter birds since the younger ones would be quite a challenge to ID to species. This is the only gull species we saw during a week on Terceira, but we saw thousands of them.
