Where have all the red squirrels gone?

Plunkety, plink, plink. My daughter Abbey got a ukulele from ol鈥� Santy himself this Christmas and I鈥檝e been plucking away at it in my spare time.
And if you don鈥檛 recognise the opening bars of the iconic 1960s folk song 鈥淲here have all the flowers gone?鈥� I don鈥檛 blame you. It might be my technique.
Or it could be because I鈥檝e rewritten it to 鈥淲here have all the red squirrels gone?鈥�
It鈥檚 a bit of a mystery. We were away for about a week over New Years, and when we got back, our two red squirrels seemed to have disappeared.
I was tempted to suggest alien abduction. Then, after sober second thought, I decided no alien in their right minds would want a red squirrel running around their spaceship, chewing on wires, pulling insulation out of the walls, and chattering away.
In my post-holiday haze, admittedly, I didn鈥檛 even realise that the squirrels had disappeared for at least a week after our return. The weather had turned cold, with daytime highs of -20潞 C and I just assumed that the squirrels were holed up somewhere warm and cosy.
But, given that at least one of them would show up eyeballing the bird feeder on even the coldest days, I finally figured something was amiss.
And, losing one squirrel is odd, but losing two in less than a week is downright mysterious.
Another point of clarification. When I refer to the two squirrels, I don鈥檛 want you to think that they were friends or anything. The big squirrel seemed happiest when it was trying to kill the smaller one. Like siblings.
Nor, as is the case in most things in this world, did the two squirrels equally share their resources. The big one could be classified as the 鈥渉ave鈥� squirrel, and the other 鈥渉ave-not.鈥�
The poorer 鈥渉ave-not鈥� squirrel was stuck living on the south side of the house, well away from the bird feeder.
It only had about six spruce trees to depend upon for cones and shelter, although the one thing it had going for it was an abundance of hazel shrubs.
The 鈥渉ave鈥� squirrel definitely had more resources. With at least 20 spruces to choose from, plus a bird feeder, a couple of sheds to call home and also an abundance of hazel, this squirrel was the Donald Trump of rodents.
But evidently even the Trumps of the world can have troubles. 鈥淗ave鈥� squirrel was suffering from a change in management鈥� this fall, I changed how I fed the birds, making it harder for a squirrel to steal sunflower seeds. And then we went on vacation for a week and left the birds and squirrels to their own devices.
As I pondered the squirrels鈥� disappearance, I first wondered about predators like fishers or pine martens. We鈥檝e had them go through the yard before, but they never seemed to cut down on the squirrel population. And there hadn鈥檛 been any fresh signs of fishers or martens in the yard for a while.
As an alternative, could both squirrels have decided to up and move? It鈥檚 possible, but squirrels are highly territorial, and will fight to the death to hold onto their homes. So a squirrel would find it hard to move into an area where there was already a resident squirrel. And, in our part of the country, pretty much every territory is occupied. Or at least they had been.
On my snowshoe routes this year, I鈥檝e been noticing a general lack of squirrel sign. It seems to me that it was not only my squirrels that disappeared.
In the end, I think that many squirrels have run out of food. I have written before about my non-scientific surveys of spruce tree cones and hazelnuts.
Interestingly, this year was the least productive that I have seen in my 10 years of looking at these crops. I didn鈥檛 see a single spruce tree with new cones on it this year, and the production of hazel nuts was the poorest I鈥檝e seen.
Squirrels are well known for being hoarders. They will lay in enough supplies for up to two years, hiding cones, nuts, seeds, and mushrooms in all sorts of nooks and crannies. But even these larders can be emptied in times of scarcity. And that is what the squirrels might be facing鈥� last year wasn鈥檛 a real productive year for nuts and cones either, and so I think that many squirrels have used up a lot of their reserves. Not that I鈥檓 saying all the squirrels are starving. Last summer, I found a hazel shrub with 26 nuts on it (close to an all-time high), and if you were a squirrel lucky enough to have a few of those shrubs in your territory, you鈥檙e probably doing fine.
Or, you could live next to a constantly stocked bird feeder. Hmmm I think that actually works. Sing along, everyone: 鈥淕one to bird feeders every one. When will they ever learn? When will they e-v-e-r learn?鈥︹�� Plink. Plank. Plunk.
