Introduction
Mammals are the best known animals in our area, but are often the least
conspicuous. Most are quite shy and many are nocturnal, so they
are seldom seen.
Below, I have listed the species of mammals found on the property
during
this study.
Except for the few animals I saw while out looking for plants and
birds, I identified most mammals from their tracks during the few snows
of the winter or from carcasses dragged in by the cats and dogs.
The two large dogs who range across the property keep the large mammal
population in check while the cats serve a similar purpose for the
small mammals. To some extent, this is helpful since these
domesticated animals take the place of large predators (such as wolves
and mountain lions) which have been extirpated from our area.
However, the property shows some signs of over-hunting by the
dogs. I would
have expected to see several species which were not sighted during this
year - Virginia Opossum, Red Fox, and Woodchuck being the most glaring
omissions.
Species List
Northern Short-tailed Shrew (Blarina
brevicauda)
Shrews are primarily subterranean,
spending most of their life below the earth's surface. The cats
only
dragged in one shrew,
which was of this species. However, tracks in the snow suggest
that
shrews are relatively common on the property. Several other
species could be found here as well.
Hairy-tailed Mole (Parascalops breweri)
Moles are even more subterranean than
shrews, seldom coming above ground. The cats dragged in one
Hairy-tailed Mole. I also found mole tunnels at a few points on
the
property, denoting mole activity which could have been this or another
species.
Bat
I saw a few bats flying in the evening
above Wortroot Cove. They could have been any of several
species.
Gray Fox (Urocyon cinereoargenteus)
This species was identified from tracks
in the snow in the woods. The tracks might possibly have been
from a Red Fox,
or even from a small dog though its behavior was fox-like. Only a
few
signs of this species were found, so it is probably relatively rare
on the property.
Raccoon (Procyon loton)
A few sightings of tracks suggest that
raccoons occasionally range over the property in the woods.
Mink (Mustela vison)
One found dead at the new site.
Since mink are shy and nocturnal, there could be others present near
wet areas on the property.
Striped Skunk (Mephitis mephitis)
Tracks and frequent skunk scent on the
dogs suggest that a few skunks live on the property in the woods.
White-tailed Deer (Odocoileus
virginianus)
Deer are relatively frequent on the
property, though only in the far reaches of the woods (most commonly
near the top of
Middle Cave Ridge).
Eastern Chipmunk (Tamias striatus)
Chipmunks are seen relatively
frequently on the property in the woods.
Gray Squirrel (Sciurus carolinensis)
Gray Squirrels are the mammal most
commonly seen on the property. Squirrels can be found
throughout the wooded areas.
Mouse
Tracks of mice (probably White-footed (Peromyscus leucopus) or Deer (Peromyscus maniculatus)) were found
relatively frequently in the woods of the property. In addition,
mice
(probably the alien House Mouse (Mus
musculus)) live in the house. Finally, I saw one mouse in
open woods which looked like a Golden Mouse (Peromyscus nuttalli).
Vole
I found a few vole tracks at wood
edges. The tracks could
have represented any one of several species.
Eastern Cottontail (Sylvilagus
floridanus)
Cottontails are seen relatively
frequently in brambly parts of the property. Most were adults,
but I also found a nest of young rabbits.
Further Study
Small mammals require specialized sampling. Most of my small
mammal sampling consisted of identifying those which had been killed by
the cats, so further study is merited.
