has found color perception in deer is much like that of a human who is<br />
red-green color blind (Jacobs et al. 1994). A deer’s sense of hearing is<br />
very acute. Large, moveable ears allow them to detect sounds at great<br />
distances and pinpoint the direction of these sounds.<br />
Perhaps most important to deer is their sense of smell. Relative<br />
to most other species of wildlife, deer have extremely elongated<br />
noses. Within this nose is an intricate system of nasal passages that<br />
provides a large surface area for olfactory (smell) perception. The tissue<br />
lining the nasal passages contains millions of olfactory receptor sites.<br />
Among wildlife species, deer have one of the keenest senses of smell.<br />
This extraordinary sense of smell is the primary method deer use to<br />
avoid predators—including humans. Other important functions of smell<br />
include identification of other deer, identification of food sources, and<br />
identification of individual deer relative to reproductive status. For<br />
example, bucks may use smell to identify does that are receptive to<br />
breeding.<br />
Scent communication is probably the most important aspect of<br />
a deer’s sense of smell. Researchers now have identified seven glands<br />
in white-<strong>tailed</strong> deer, most of which are used for some type of scent communication<br />
(Miller 1997). Three of these glands are located on the legs.<br />
The interdigital glands are located between the hooves of all four feet.<br />
The metatarsal glands are located on the outside of the hind legs and<br />
the tarsal glands are located on the inside of the hind legs.<br />
The tarsal gland is perhaps the most important of these glands.<br />
This structure consists of a patch of elongated hairs underlain by an<br />
area of large sebaceous glands. The sebaceous glands secrete a fatty<br />
lipid that adheres to the hairs of the tarsal gland. This area gives off a<br />
