[1] The Fascinating World of Collective Nouns for Murres: A Multitude of Astonishing Avian Assembly

A collective noun for murres is a "colony". Murres, also known as guillemots, are seabirds that inhabit coastal regions and nesting grounds throughout the Northern Hemisphere. They are known for their distinctive black and white plumage, long thin bodies, and adept to diving underwater as they search for fish. The term "colony" is used to describe a group or gathering of murres that come together in large numbers during the breeding season. At these colonies, hundreds or even thousands of individuals will nest and raise their young on rocky cliffs and ledges overlooking the sea. Colonies can be found along and near coastlines, particularly in areas of cold-temperate to Arctic climates. The collective behavior of murres within a colony serves various purposes, including protection against predators, facilitating shared nesting resources, and enhancing reproductive success through communal mating displays. Murres unite in these colonies every year, creating a mesmerizing sight and showcasing the remarkable social dynamics of these fascinating birds.
