Loss of Oaks

Yes, The Squirrel Nutwork is still on winter hiatus, but our recent weather is prompting us to speak for the trees!

Like most of the east coast, we had high winds in northern Virginia over the weekend. Sadly, our suburban woodlands around the golf course lost many old oaks, a loss for both the human and wildlife inhabitants.

Many were snapped off, but a closer look showed that the heartwood of the tree was rotten.

Unfortunately, these older trees had such a branch spread of strong limbs that they took down adjacent trees.

One was apparently decayed enough at the base and roots that it uprooted.

We squirrels noted that recent replacement of the sidewalk adjacent to this last double oak had also included a regrading of the entire soil bed surrounding the tree… The tree was rotten, but it’s never a good idea to mess with the roots of a tree! They extend farther than most humans think–one and a half times the diameter of the branch spread. Good thing to keep in mind to help your trees weather storms like we seem to be having more frequently.

Hey there!

Quiet week here. I think this is an easy guess of most humans, but, hey, I’ll throw it out there anyway!

Be back later for your guesses!


All–nearly all!–they leaves on the ground here are oaks. The yellow leaves amid the coppery brown ones are  a branch form a White Oak tree. It’s one I–Hickory Squirrel–cut myself to add to my leaf nest. That’s why it’s a bit fresher than the rest of the red oak leaves that fell naturally.

Chilly nights, you know! We all need to add our layers.

Hey there!

It’s a weekend to celebrate our mystery column: This is the two hundredth mystery post on The Squirrel Nutwork!

And what better way to celebrate than with a mystery acorn!

Sigh, isn’t that a lovely sight?

That’s not too hard, is it? I mean, to guess what type of oak tree it came from?

I’ll check for your guesses in the comments–and if you really want a hint…here is one pictured below.


This beautiful acorn is from the Black Oak, Quercus velutina. Yes, it’s hard to tell the similar leaves of the black and red oak families apart. One way is the acorns. The Black Oak acorns are shorter and round. The leaves of the Black Oak turn a coppery color in the fall, not red like the Northern Red Oak. And, this is the best leaf difference any time of year, on the back of a Black Oak leaf, tufts of hair fill the angle of space between the main vein and the branching veins (called the axil!). Hope you human readers can see those tufts on the lower, yellowish, dotted leaf.

But either tree is beautiful to us squirrels and the acorns tasty!

And falling like crazy with the winds coming through!

Hey there!

Something edible–for wildlife only!–is ripening now.

If you have a guess of what it is, please post in the comments. I’ll check back later!


Maybe another hint?

The fruits of the Flowering Dogwood, Cornus florida, are ripening now and their flesh being picked at by the birds: Cardinals, titmice, bluebirds, and the juncos–when they arrive.

They won’t last long, even if they aren’t very tasty! We squirrels find that birds are’t that picky.

Hey there!

It’s not only acorns that are falling, the leaves are following…

or more specifically, this leaf has fallen. If you know what kind it is, or just have a guess and want to play, give me an answer in the comments!


We squirrels don’t see this too often–a doubly compound leaf. The smaller leaflets are actually leaflets of the larger leaf. In fact, Miz Flora tells us that this small tree can even have triply compound leaves!

It’s a Devil’s Walkingstick or Hercules Club, Aralia spinosa, which if you try to climb the trunk, your paws will tell you exactly correct. Usually growing at the sunny edges of woods, this native tree can grow to 20 feet tall where they lean their huge flower heads out, letting bees and butterflies find them.

Now, in the fall, each of the tiny flowers has become a berry.

We squirrels don’t eat them–can’t get to them!–but they seem to disappear. It’s the birds, of course, thrushes, sparrows and pigeons, but Miz Flora says she’s seen fox and skunk eating them. And chipmunks–they must be waiting for them to fall! That’s the only way to get them that Nutmeg and I can figure out.


Even if it’s not something we eat, this is a pretty cool tree that seems almost hidden from humans.
