Who’s afraid of the big, bad wolf? Coyotes.
While _coyotes _

predators in many parts of the country, they seem to be wary of their Canis
cousin, the wolf, with coyote densities dropping by a third in wolf territory, a
new study finds.
The research, detailed online by the Journal of Animal Ecology, examined the
effects of wolves on coyote populations in Grand Teton National Park and the
southern greater Yellowstone ecosystem.
Researchers followed radio-collared coyotes and found that while there are
always more coyotes than wolves, there were fewer coyotes in the places where
the two species overlapped.
Coyote densities were 33 percent lower in the areas they shared with wolves
in Grand Teton and 39 percent lower in the areas of Yellowstone where wolves
were _recently reintroduced_
(http://www.livescience.com/environment/wolf_ecosystem_041209.html) .
About 16 percent of radio-collared coyotes were _preyed upon_
(http://www.livescience.com/animals/060802_brain_prey.html) by wolves, the study found.
Relative safety came only in numbers as coyotes without packs were more
likely to become the wolves' dinner. Lone coyotes were also much more likely to
leave an area inhabited by wolves than coyotes living in packs.
“The study tests the hitherto unproven hypothesis that wolves limit the range
and numbers of coyotes in places where the two species compete with one
another,” said study leader Kim Murray Berger, a Wildlife Conservation Society
researcher. “In this instance, the findings do support the theory, but coyotes
can hold their own against wolves by living in packs.”
Humans are actually a bigger threat to coyotes than wolves, with 29 percent
of the coyote mortality in the study attributable to human activities.
