Genus Uria, also known as the guillemots, encompasses several species of sea birds that belong to the family Alcidae. These birds are primarily found in the Arctic and the sub-Arctic regions of the world. The Guillemots are known for their long wings, black plumage and distinctive white underparts which are often speckled as well. While the term genus Uria is the scientific name for these birds, they are also referred to as the murres or auks. These synonyms not only simplify communication but also help to widen their appeal and understanding to a broader range of individuals.
