The Great Black-backed Gull (Larus marinus) is the largest gull species in the world, easily recognized by its imposing size, dark black back, and powerful yellow bill. Seen very often around the puffin islands in Faxaflói Bay, this dominant predator is a frequent presence in the area. Great Black-backed Gulls are opportunistic feeders, preying on fish, scavenging along the shoreline, and occasionally hunting smaller seabirds, including puffins. Their role as both predator and scavenger highlights their adaptability and importance within the coastal ecosystem. Observing these formidable gulls offers a glimpse into the natural balance of life on Iceland’s seabird-rich islands.
