Looks somewhat like a German shepherd dog with a yellowish gray coat
and long, bushy tail. The coyote has a pointed nose, and a heavy tail
which, when the animal is running, seems to float behind. Total length
about 4 feet; weight up to 35 pounds. This species of coyote is
usually larger than the familiar plains variety, and may be confused
only with the larger wolf, which has disappeared from this region.
This crafty and bold "wild dog" is very common and increasing in the
entire area, from the lower hills to above timberline. Their increase
may be accounted for not only by their extreme cunning and adaptability
to the invasion of man, but also because they produce the high average
litter of six young each year. Scarcity of food, persecution by man, and
the great stamina of coyotes has helped him become the outstanding
predator in North America, both in numbers and extent of range. They
will eat practically anything--birds, insects, carrion, rodents,
rabbits; and when in packs can overcome large game animals, which are in
a weakened condition due to severe winters. I have seen coyotes in many
of the lower valleys of the Park in mid-morning hours, "playing" with
ground squirrels. They grab and fling them several times into the air,
catching them expertly each time and finally gulping them down. The
coyote becomes more awesome if you have heard its weird howl floating
out of a moonlight night.
