A fallen tree trunk is a piece of woodland motorway as far as the wood’s denizens are concerned, a clear path for getting from A to B. However, it contains interior passages crammed with food items, so doubles as a service station as well. So I reasoned when I set up my camera trap to look along the top surface of the fallen and mouldering giant.

And so it proved. The camera revealed wood mice scampering along at great speed, no doubt influenced by the dread of the local tawny owl. During September, the camera showed that these risky excursions took place, on average, four times a night, and also showed that voles and shrews made the occasional appearance.

Last Saturday, I returned from the wood with the SD cards from the cameras and started going through the files on my computer. This one, taken just before 7 o’clock in the morning the previous Friday, had me whooping with excitement:

Twenty minutes later, the weasel showed up again, but then there was nothing for the rest of the day, and I thought that the weasel was just passing through. Then I started looking at the files from the next day, and at 8.45 am, there was the weasel again, and this time, it stayed all day, popping in and out of the crack in the log, exuding that aura of both cuteness and ferocity that is so characteristic of their kind.

And there was more than one weasel – in some of the video clips, the weasel looking distinctly younger, and one clip showed both weasels flowing one after the other along the crack in the log.

In all, there were 39 hits spread through the day, from 8.45 am to 5.50 pm. Presumably, they had a rest then because there was no activity until one hit at 1.35 am that night. There was then no sign of the weasels until the following day, Monday, when the final hit occurred at 1.09 pm:

There were no weasels on the camera trap for the next three days, up to the point where I collected the SD cards from the camera, so they have moved on. I am eager to see the next installment from the fallen tree just in case, but I don’t expect to see them back for a while.
