The
Mountain goat (Oreamnos americanus), also known as
the Rocky Mountain goat, is found only in the northwestern
regions of North America. Although it resembles a goat, it
is not a true goat, being of a different genus. They are of
the order Artiodactyla and the family Bovidae,
along with antelope and cattle. These animals reside at high
elevations and are sure-footed climbers, often resting on
rocky cliffs that predators cannot reach.
Both male (billy) and female (nanny) mountain goats have
beards, short tails, and black horns, 10-12 inches in length.
They are protected from the elements by their woolly white
coats. The fine, dense wool of their undercoat is covered
by an outer layer of longer hairs. In the winter, their coats
help them to withstand temperatures as low as -50° F and
winds of up to 100 mph.
A billy weighs about 200 lbs, while females average around
150 lbs. The billies have longer horns and a longer beard
than the nannies. Their feet are well-suited for climbing
steep, rocky slopes, sometimes with pitches of 60° or
more, with inner pads that provide traction and hooves that
can spread apart as needed. Claws on the back of their feet
also help to keep them from slipping.
The mountain goat inhabits mainly the Rocky Mountains and
Cascade Mountain Range regions of North America. They can
be found from Alaska south through British Columbia and Alberta
and down into Oregon, eastward into Idaho, Utah and Montana,
with South Dakota being the furthest east you will find them.
Colorado is the furthest south their territory goes; in fact,
our mountains to the east of town are just about their southern
limit.
British Columbia has the largest population of mountain goats;
there are believed to number around 100,000. In Colorado there
are about 1,600. Yes, we have a few mountain goats in our
mountains above Crestone, but only a few. It is estimated
that there are only between 1 to 5 mountain goats in our mountains
at this time, as most of them stay to the north, in the Collegiate
Peaks where their numbers are greater.
In this area, and unlike bighorn sheep, mountain goats usually
never wander down below 11,000 feet, and have been spotted
as high up as 14,000 feet. They are known to descend to as
low as sea level in coastal areas, but they are primarily
an alpine species.
Mountain goats normally summer in high alpine meadows where
they graze on grasses, herbs, and shrubs. Most migrate from
alpine summer ranges to winter at or below tree line, but
some may remain on high ridges. As winter advances and the
more succulent plant species die off, their feeding habits
shift to browsing.
Kids are born in the spring after a six month gestation period.
Usually nannies give birth to a single offspring. Twinning
occurs rarely, but is more frequent following mild winters.
At birth, kids stand only about 13 inches at the shoulder
and weigh just 5 to 7 lbs. They are precocious, and begin
to run and climb within hours of their birth. They are usually
weaned within one month, yet follow their mothers closely
for the first year of life, usually until she reproduces again.
In the wild, mountain goats usually live 12 to 15 years.
In zoos however, they live up to 20 years. They are prey to
coyotes, mountain lions, bears and bobcats. Even though their
size protects them from other predators in the highest of
altitudes, females still must defend their young from eagles,
which can be a threat to very young kids.
So, if you have an interest in viewing these animals, it
is suggested that you head up north to the Collegiates to
do so. Yes, you just might see one of them even up in our
mountains—if you’re lucky, that is.
