The Père David's deer (Elaphurus davidianus), also known as the milu (Chinese: 麋鹿) or elaphure, is a species of deer native to the subtropical river valleys of China. It grazes mainly on grass and aquatic plants. It is the only extant member of the genus Elaphurus. Some experts suggest demoting Elaphurus to a subgenus of Cervus. Based on genetic comparisons, Pere David's deer is closely related to Eld's deer.
