Anotations

Scope note:

Members of a genus containing four living species of sea birds having a short neck, black and white plumage (which resembles monastic robes, thus the genus name "Fratercula"), and a large, multicolored, laterally compressed, grooved bill that is brightly colored in the breeding season. They feed primarily by diving; they breed in large colonies on coastal cliffs or offshore islands.
