Predators' effects on biodiversity
are often misunderstood, as they
are perceived as bloodthirsty killers
that only take from the scene. While
the cats no doubt kill many deer and
other animals, potential benefits
from their existence must also be
realized. For instance, as a matter of
efficiency cougars often first prey upon
easily targeted ill or weak animals.
Consequently, the herd may benefit
from improved genetics and reduced
disease transmission. In addition,
recent research in the West has
shown that mountain lion kills can
be beneficial to many other species.
At this site in Sheridan County, black-
billed magpies and golden eagles
feasted on a cached white-tailed deer
– still leaving some for the cat to eat,
of course.
