The Black-headed Gull (Chroicocephalus ridibundus) is a small, elegant gull easily recognized by its white body, pale gray wings, and distinctive dark chocolate-brown head during the breeding season (which appears black from a distance). These adaptable birds are often seen in Faxaflói Bay, where they can be observed gracefully flying over the water or resting along the shore. Opportunistic feeders, Black-headed Gulls thrive on a diet of small fish, insects, and scraps, showcasing their adaptability to various environments. Their frequent presence in the bay highlights the area's rich food resources and its role as a vital habitat for coastal bird species.
