The Attentiveness of the Deer
A team at the Cusino Wildlife Experiment Station in Michigan decided
to test the
skill (and attentiveness) of deer. Thirty-nine deer were released
inside a onesquare-
mile, escape-proof, wood-and-swamp habitat. Sometime later, six skilled
hunters entered the enclosed area. A layer of snow provided the hunters
with ideal
conditions for tracking their game.
One day passed, and the hunters spotted no deer. Then a second day
passed—still
no deer. A third passed, and then a fourth day arrived before any
of the hunters
saw even one deer. It took 6 experienced hunters 51 hours to locate
a single deer!
Who was more attentive?
Even a fawn can maintain the swift 30-mph pace set by adult deer
as they flee
through the woods.With great agility, deer can maneuver a heavily obstructed
woodland course.
Layers of tough cartilage between the bones of the deer’s forelegs
and skeleton
serve as heavy-duty shock absorbers. This allows the fleeing deer
to stop and
turn “on a dime” without damaging its legs.
When a fawn is born, its mother licks it completely clean, eliminating
any odors
that might attract the alert noses of predators.
The newborn’s coat is spattered with 250–350 creamy white spots.
These spots
allow a fawn to blend almost imperceptibly with the sunspots shining
through
the leafy trees onto the woodland floor
Although older deer no longer sport the protective spots, their earth
tone coloring
helps them hide easily.
White-tailed deer have extremely sharp noses. Deer use their noses
extensively,
not only in their watch for danger, but also in their communications
within the
deer community. Scientists have identified seven different skin glands,
in addition
to excrement, that deer use to leave aromatic “signposts” for
other deer.
Deer also have good eyes. Although deer are commonly believed to
be colorblind,
there is evidence that this might not be completely true. Even in
semidarkness,
a deer watches closely for any motion. Once it sees something move,
the deer pricks up the sharpest of all its receptors: its ears.
Studies have shown that the deer’s hearing is so acute that without
even lifting
its head, it can discern the difference between the steps of another
deer, a bear,
or a human. Just because a deer continues grazing does not mean it
is unaware
of a person’s presence. While eating, the deer is constantly turning
its ears, monitoring
the precise location and activities of the other deer in the herd.
If it hears
the sound of another deer running, it will run as well.
The deer also walks with a cautious, inconsistent gait. By alternately
stepping and
stopping, the deer keeps its own footfall from covering other woodland
noises.
