The Black Guillemot (Cepphus grylle) is a striking seabird, easily identified by its black plumage with bold white wing patches and bright red legs. This resilient bird nests along rocky shores and coastal cliffs, often found around Faxaflói Bay. Known for its strong swimming and diving skills, the Black Guillemot primarily feeds on fish and marine invertebrates, diving to impressive depths. Observing a Black Guillemot colony offers insights into their unique breeding behaviors and their adaptation to changing marine environments, playing an important role in coastal ecosystem dynamics.
