The forest behind our home has long served as my classroom and this past week has been no different.

Upon several occasions, through the doorway I stepped. My intention initially was to stalk some porcupines I’d tracked previously in hopes of finding at least one of them in a tree. But the three dens that had been active two weeks ago were empty.

Near one located almost a mile from home, however, I spied squirrel middens dotting the landscape. This was in the late afternoon of Wednesday, February 23, a day when the high temperature broke records and reached 62˚ in western Maine.

For a brief second I spied the squirrel responsible for the middens, but then it scrambled up a hemlock and disappeared from my sight.

And so I . . . I decided to try to examine its territory and exclaimed when I realized that because of the warm temperature, its tunnels had been exposed. This particular one led to one of its food storage units, a cache of hemlock cones stored under a downed tree.

Into the mix it was more than the squirrel, for I spied vole tunnels and deer prints. So here’s the thing, red squirrels tunnel through the deep snow to get to their caches. Of course, they also leap across the snow. Voles, on the other hand, are much shier of sky space because they are everyone’s favorite food. They tunnel between the ground and the snow in what’s technically called the subnivean zone and typically we don’t see their exposed runways until spring. But 62˚is like an early summer day ’round these parts. Oh, and do you see that same downed tree from the last photo? Keep it in mind, for it plays an important role in this story.

A vole’s tunnel is about an inch across and the only thing I had for a reference point was a set of keys. I was traveling light that day.

Likewise, the squirrel’s tunnel was about three inches in width.

My next move was to walk the perimeter of the squirrel activity in order to gain a better understanding of its territory. All told, it is about 30′ x 50′, and located under several tall pines and hemlocks that create a substantial canopy. On the fringe of this particular neighborhood live a few red maple and balsam fir saplings.

I had to wonder if the squirrel was still in the hemlock or had moved to a different location via its tree limb highway while I was looking down and all around.

Having figured that out, I returned to the downed tree, for not only did it serve as a food storage or cache below, but the top side was the dining table/refuse pile, aka midden. Obviously the hemlock had provided a great source of food–a good thing given that it seemed to be the only hard mast available this year.

There were other middens scattered about, but I really liked this one upon a stump, which showed the pines had at least offered a few treats not yet devoured. The thing is, red squirrels like to dine on high places, whether it be upon a downed tree, stump, or even up on a limb. That way they can see their predators approach and make a mad dash to a tunnel or up a tree trunk.

Two days later, on Friday, February 25, seven or eight inches of snow fell and again in the later afternoon I ventured into the woods to check on the squirrel’s activity. Sometimes during storms mammals hunker down but by the number of prints visible, I knew that this one hadn’t. Its tunnels had some snow in them, but the boughs above kept much of the snow from landing on the ground.

The curious thing for me was that though there was a lot of activity by the downed tree, I couldn’t locate a single midden. Even if the squirrel had been dining on a tree limb, surely some cone scales and cobs would have fallen.

It had also climbed its favorite tree, the one where I spied it on Wednesday, but again, no sign of food devoured.

After my guy and I spent the morning and early afternoon tramping four miles from home to a swamp and back, I decided to head back out to check on the squirrel while my guy went for a run. Speaking of running, as I approached the squirrel’s territory, I watched it run across the snow and zoom up the hemlock and never spied it again.

So I turned to the tree stump–it was covered with Friday’s snow, though there were tracks around the base of it. What I loved is what I’d missed on Friday–barbed wire. This was all once farmland and obviously I was standing on a boundary. It was actually a boundary for the squirrel as well, since this marked an edge of its territory.

Near the red maple saplings I found evidence of some fresh tunneling, albeit not under the snow, but through it, which is also typical. Perhaps the squirrel was dining within and had hidden its middens.

I stepped over to the downed tree and looked under in a southerly direction, curious to see barely a sign of the cache that had been so evident on the first day.

Looking north, it was more of the same.

That is . . . until it wasn’t. A hint of color captured my attention. Feathers?

No. Hair. From a red squirrel, whose hair hues can range from gray to brown to red. A fluffy tail no more. The thing is that squirrels sometimes loose their tails to predators, or even parts of the tail from a fracas during a territorial fight with one of its own. Another cause may be a tree trying to snag the tail just as speckled alder and winterberries and balsam fir tried to snag my hat repeatedly on our tramp this morning.

Even upon the downed tree . . . a little tuft. No tracks atop the tree. And no signs of feeding.

I looked around, searching for predator tracks and instead found the snow lobster instead. This was a place of squirrel and vole and deer and hare. But not a predator in sight.

And so I looked up, thinking that the hair was the result of an avian predator. My hope was to find a few strands dangling from a tree. Or some other evidence. Nothing. Oh, how I wished GLLT’s Tuesday Trackers were with me, for they are an inquisitive group and ask great questions and process the whole picture in a complete manner. Together we share a brain and I needed that sharing.

Alas, they were not, but I snatched some of the hair and will certainly share it with them in the morn.

In the meantime, that’s my tale of the squirrel’s tail. And if you have ideas or considerations, please let me know.
