Every one feels aroused and lustful at times.

Sometimes one part of your body feels aroused, and sometimes another.

But have your teeth ever felt aroused?

No?

Well, that proves that you are not a tree squirrel.

Previous posts on this blog have wondered what drives tree squirrels into a frenzy of arboreal vandalism several times each year.  The most recent of those posts was here.

At last, we have an answer.

A local citizen’s association sponsored a walk through a local park, with a park ranger to show us how to identify the type of each tree, and to explain its ecological role and prospects.

The ranger provided the long-sought explanation of what drove the tree squirrels to their periodic frenzies of vandalism.

The squirrels are not teething, but are driven by something close to teething.

A squirrel’s teeth would become over-long unless the squirrel gnawed on something hard.

Wikipedia confirms and expands upon this explanation: tree squirrel’s’ “characteristic gnawing trait also aids in maintaining sharp teeth, and because their teeth grow continuously, prevents [the] over-growth [of their teeth].”

In short, tree squirrels have aroused teeth!

Vandalism by tree squirrels isn’t confined to trees. Tree squirrels occasionally chew on electrical wiring, sometimes in the attic of a house, or strung between poles outside.

Their non-arboreal vandalism probably has the same explanation as their vandalism of trees.


The topic of this blog posting obliges me to end it on a more personal note.

As is clear from my picture, I am a prairie dog.

While researching squirrel teeth for this post, a relevant Wikipedia article contained this bombshell: “Prairie dogs … are a type of ground squirrel …”

Imagine my astonishment! This post has been about my own distant cousins!

Of course, prairie dogs differ from tree squirrels in important ways. That is why I have been careful throughout to call them tree squirrels.

Now, about those differences.

Prairie dogs hate black-footed ferrets. Not only are those sharp toothed nasty- dispositioned fiends of the right size to creep into our burrows, they do not read advice columnists, and therefore have no sense of boundaries.

Tree squirrels do not have nightmares about black-footed ferrets.

On the other hand, prairie dogs are much bigger than tree squirrels, because our weight is not limited by the strength of the branches of the most numerous trees. So our paws are much bigger, too, and that is what enabled me to write this blog. With a small stubby strap-on on each front paw, two-pawed typing is possible on a keyboard. It is very similar to two-fingered typing by a person. With a strap-on, I can even swipe a touch screen. (A bare paw doesn’t work on a touch screen. A bare paw produces too complicated an imprint for a computer that is looking for the simple dot-like pattern of a finger tip.)

The paw of a tree squirrel is too narrow to serve as the stable mount for a strap-on.

Those are some of the differences.

But still, they are cousins.

So I have three wishes for them:
– teeth that are sharp and not over-long,
– the discernment to distinguish an insulated electrical wire from a twig,
– and the understanding that although random changes of direction do help when escaping from a pursuing animal, they do not help when evading a car.

Squirrels Teething?

In the late Spring, freshly bitten-off young branches rain down from the trees.

In the late Fall, it happens again, but less intensely.

Squirrels are the obvious culprit.  But the chewed-off branches show no sign of having been eaten, even partially.

Why do the squirrels do it?  Why the frenzied activity?

Here is a guess.

In the Spring and Fall, new litters of baby squirrels are born.  By the late Spring and Fall, the new squirrels are developing rapidly.

When a human baby’s teeth start to develop and push out through the gums, the baby teethes.  The baby gnaws on anything handy, to try to quell the soreness of its gums.

Are the baby squirrels teething?

You can help answer this question.  If your home or your office has a window that looks at the branches of trees, see whether only the young squirrels are gnawing off the branches.

Comment to this post, to say what you have noticed.

Also, do squirrels ever gnaw the young branches of an evergreen when a deciduous tree is available?  We have never found a gnawed-off evergreen branch, but all the trees near our house are deciduous.  Maybe the young branches of an evergreen taste too bitter, so that a deciduous tree will be preferred over an evergreen wherever both are available.

It is easy to imagine a baby fish or alligator being born with tiny teeth.  The fish and the alligator do not depend on milk direct from their mother’s body.  But a baby mammal must be born toothless.  Otherwise its mother would not allow it to drink from her.

In fact, the age when teeth first develop probably marks the age at which babies in the wild stop drinking their mother’s milk.

But these are mere guesses.  I have no knowledge on those topics.  If you know more, please comment.
