The Sitka deer, Odocoileus hemionus subspecies sitkensis, is a subspecies of Black-tailed Deer that inhabits northern British Columbia, Canada and southeastern Alaska, United States. It is characteristically smaller than other types of black-tailed deer, probably due in part to its typical island habitat. It is also a fairly good swimmer, and can occasionally be seen crossing deep channels between islands. It is named after Sitka, Alaska.
Sitka Deer eat green leaves. Fawns are born in the early June and weigh 6 to 8 pounds. Their average life span is about 10 years but a few are known to have attained an age of 15.
