Chen caerulescens is a scientific name for the snow goose species. The name has its origins in Latin, with chen meaning "goose" and caerulescens meaning "bluish-grey." There are several synonyms for this species, including Anser caerulescens, Chen hyperborea, and Chen albatus. Anser caerulescens is an older name that was once used to refer to this bird, while Chen hyperborea and Chen albatus are both still used in some scientific circles. It is important to note that while these names may be used interchangeably, they all refer to the same species of goose that is known for its stunning white plumage and beautiful black flight feathers.
