The Brünnich's Guillemot (Uria lomvia) is a hardy seabird, distinguished by its black head and back, contrasted with white underparts, and its shorter, thicker beak compared to the Common Guillemot. This bird is known for nesting on high Arctic cliffs, forming vast colonies on steep ledges. Brünnich's Guillemots are excellent divers, often reaching great depths to catch fish and other marine creatures. Observing Brünnich's Guillemot colonies offers insights into their breeding strategies and their ability to survive in extreme Arctic environments, making them essential indicators of oceanic and climate change impacts in polar ecosystems.
