The Shawnee word for elk is wapiti
meaning "white rump." Elk are about 4-5 feet tall at the shoulder and weigh from
325-800 lbs.
Males are much bigger than females and have branching antlers which shed and
re-grow each year. Elk antlers sweep back whereas
white-tailed antlers sweep forward.
Elk are herbivores and spend a lot of time browsing. Elk
are ruminants; they store partly-chewed food, later regurgitate and thoroughly
chew it. They are very social animals, living in herds. Older bulls (male elk)
tend to become solitary, or stay in smaller groups, joining
the herd when the rutting season (breeding period) begins in the fall.
Bulls bugle to attract cows (female elk) and will gather
a harem of cows to breed with throughout the rut. Researchers in Wisconsin
heard the first fall bugling on September 11 in 2001 and 2002. Last year,
bugling began on September 5. Bulls are mature in their
second autumn, but generally wont join a harem and breed until the fourth
autumn.
Cows reach mature breeding age at about 28 months. Cows are
in estrus for no more than two days. A bull elk will single out and
tend to a female in estrus for 24 hours. During the rut, a bull elk will spray
urine on its belly to show self-confidence to the female.
A bull may not eat, drink or sleep for the duration of the rut if there are
several cows in estrus.
The
gestation period for an elk is approximately eight and half months. Cows produce
one calf per year, and rarely have twins. The calves are born mid-May to
mid-June.
The earliest known calf birth in Wisconsin was May 20. In 2004, DNR elk
biologist,
Laine Stowell, expects about 24 calves to be born.
Cows move away from the herd to give birth, and will stay
on their own for about a
month until the calf is strong enough to join the herd. Average birth weight for
calves is
35 lbs. Calves are light brown with white spots, similar to white-tailed deer.
Newborns
carry very little scent, helping them remain inconspicuous to predators. Calves
nurse from
their mother until they are about 2 months old when they begin to add forage to
their diet.
A 5 to 6 month old elk calf will be about the same size as an adult white-tailed
doe.
Gray wolves and black bears are predators of the elk herd
in Wisconsin. Black bears prey mainly on newborn calves whereas wolves can
bring down mature elk. Wolves are more likely to prey on juvenile animals over
adults because they constitute an easier meal. Biologists
with the WDNR speculated that wolf predation greatly influences the home ranges
and distributions of elk in Wisconsin. By examining the
relationship of elk locations to wolf pack territories, researchers hope to
identify a pattern of elk movements in relation to predation.
Unlike other ungulates, elk have a pair of canine teeth in
the upper jaw. These ivories have no real function and wear out like other
teeth.
The ivories historically were used as decoration and jewelry by Native
Americans.
