Grulla monje Grus monacha

A small, somber-colored crane of expansive agricultural fields and wetlands. Rare outside of its main wintering grounds in southern Japan, western Korea, and eastern China, where it gathers in small family units as well as massive flocks. Adults have dark gray bodies, a white head and neck, and a dark red forehead. Juveniles are similar but have a brown-tinged head and neck and a dark smudge on the forehead instead of a red patch.
