Common Murre

Fascinating facts about the Common Murre

• A common murre's egg is shaped like a pear — pointy at one end, bulbous at the other. Roll it on a cliff ledge and it spins in a circle instead of tumbling off. No nest, no cup, no protection: just this one geometric trick that has kept murre colonies alive on exposed rock faces for millions of years.
• Common murres can dive to 200 metres in search of sand eels and capelin, holding their breath for up to 3 minutes. They chase prey underwater using their wings like flippers, hunting by touch in water so dark their eyes are useless. Their bones are denser than most seabirds' — a trade-off that makes them torpedoes underwater but clumsy on land.
• Chick mortality in a murre colony can spike 40% in a single season if one fish species vanishes from the North Atlantic. These birds specialise so completely on small schooling fish that when ocean temperatures shift and prey migrates elsewhere, thousands of chicks starve while parents still hunt frantically. Climate change is rewriting the timing of when fish arrive — and murres haven't learned to adapt fast enough.
• A common murre's call is a growling, guttural bark that sounds like an underwater creature rather than a bird. Parents and chicks recognise each other's voice alone among thousands nesting in the same colony — no visual confirmation needed in the chaos. At 2 weeks old, a chick launches itself from a cliff in near-darkness and swims toward the sound of its father's call.
• In 1986, over 100,000 common murres washed ashore dead along the California coast in a single die-off. Warm ocean currents had starved their food supply; thousands more disappeared in the Atlantic during the 1990s. These crashes reveal how fragile seabird populations are when they depend on just a few fish species — a warning written in beached bodies.

About the Common Murre

In the turbulent waters of the North Atlantic, the Common Murre cuts a sleek figure, its tuxedo-like feathers glistening with sea spray as it dives with precision, propelled by powerful wings that beat at a furious pace. With eyes like polished onyx, this agile bird navigates the treacherous shoreline with ease, its webbed feet barely touching the waves as it chases the schools of fish that dart through the kelp forests. As it rises to the surface, the Murre's raucous call echoes through the misty veil, a primal declaration of its dominance over this unforgiving yet majestic realm.
