Diet
Sitka deer primarily eat green vegetation. However during the intense Alaskan winters, they will also feed on woody vegetation and lichen. Sitka deer have no upper incisors, and digest vegetation through grinding plant material between their upper and lower molars. All Odocoileus are ruminants, in that they have a four chambered stomach which allows them to "ruminate" (re-chew) their food, and contains bacteria specialized in breaking down cellulose. Since this bacteria is so specialized, they have tremendous difficulty digesting strange material and can die of starvation with their bellies full of food. Sitka deer like bunch berry, foam flower, trailing raspberry, fern leaf golden thread, vaccinium, hemlock/cedar, and salmon berry bush.

Famous quotes containing the word diet:
“Television programming for children need not be saccharine or insipid in order to give to violence its proper balance in the scheme of things.... But as an endless diet for the sake of excitement and sensation in stories whose plots are vehicles for killing and torture and little more, it is not healthy for young children. Unfamiliar as yet with the full story of human response, they are being misled when they are offered perversion before they have fully learned what is sound.”
—Dorothy H. Cohen (20th century)
“Literary tradition is full of lies about poverty—the jolly beggar, the poor but happy milkmaid, the wholesome diet of porridge, etc.”
—Mason Cooley (b. 1927)
“The pills are a mother, but better,
every color and as good as sour balls.
I’m on a diet from death.”
—Anne Sexton (1928–1974)
