Common Murre: The common murre is one of the two murre species. Common Murres are dapper, black-and-white seabirds that nest in raucous throngs on crowded sea cliffs. Why there is so much variation is a question about adaptation, probably related to the murre's unusual breeding biology—incubating on open ledges with no nest and at very high densities (typically around 20 pairs per square meter). Common Murres are dapper, black-and-white seabirds that nest in raucous throngs on crowded sea cliffs. They are only seen on land during the breeding season. Adaptations for flight may have driven egg-shape variety in birds.
