The Glaucous Gull (Larus hyperboreus) is a large, powerful gull distinguished by its pale plumage, with light gray wings and a white body, and lacking the black wing tips seen in many other gulls. Relatively often seen in Faxaflói Bay, this Arctic species is a regular visitor to Iceland’s coastal waters. Glaucous Gulls are opportunistic feeders, preying on fish, scavenging, and sometimes hunting smaller birds. Their striking appearance and large size make them stand out among other gulls, offering birdwatchers a rewarding sighting. Observing Glaucous Gulls in the bay provides insight into the adaptability of seabirds in Iceland’s dynamic marine ecosystems.
