Here's the video. Listen after the weasel leaves the camera box and you can hear the trap snap shut. There was a wren in the hedge just above, calling alarm.
I also have another new camera box. This one is made so the camera can see through both entrances. It is wider than the others but also shorter, which creates a problem with the camera's limited field of view. The solution is to use a clip-on wide angle lens plus a close-focus (+0.5) lens, all held together with Blu-tack and gaffer tape.
So a lucky close encounter (for me). I won't try the trap again but I still hope to get rid of the rabbits - a job for the stoat perhaps? It is still around but usually avoids the camera box and is almost too quick for the other camera.
The weasel in the trap was male - broad and muscular. I am learning to recognise them as they are turning up fairly regularly on the cameras. Here is a female, smaller and much slimmer than the male. The Mammal Society website says she weighs 55-70g (only twice as much as a vole or mouse) and he is 105-130g.

I heard a mouse in the attic so I set a trap and caught the mouse. I put it in the new camera box, hoping to get a video of the weasel collecting the mouse. However, it was no real surprise that the weasel came in so quickly that it was already turning to leave with the mouse by the time the camera was recording.
Here's the video, not quite as good as I had hoped.
These videos were edited with the help of a new AI programme to improve image quality. It certainly improves them here and it will be interesting to see if the quality is maintained once they have been compressed by YouTube/Blogger. One downside is that the file size is massively increased and with my BT Superslow Broadband it has taken nearly nine hours to upload these four short videos. I hope you enjoyed them.
Excellent work Chris
ReplyDeleteAnother fascinating read with wonderful images!
ReplyDeleteGreat footage. I have been reading your blog for a while now and really enjoy it. I have been doing my own 'box camera-trapping' for quite a while, but have had very little luck when it comes to weasels, although I've recorded plenty of weasel prey! Any tips to increase my chances? My box is made from plastic like yours, although a bit more crude. I've just cut holes into the side and don't have a tunnel-like entrance. I wonder if that makes a difference?
ReplyDeleteMy camera boxes are modelled on the Mostela (https://link.springer.com/article/10.1007/s13364-020-00513-y) and I think the pipe-like entrance is probably helpful. It relies on the weasels' curiosity to look inside. My impression is that they also work better if camouflaged on the outside from a weasel viewpoint. Pipe size probably also matters - I had less success with smaller entrance pipes before. The final thing is to be in the right habitat. But if you have mice and voles it should be good for weasels as well.
DeleteThanks for the feedback, I will try modifying my design. I've been mostly deploying the box within dense vegetation at sites I get to visit with my job, but wonder if I need to focus more on linear features. The only time I've had a weasel visit so far was when the box was placed at the base of hedgerow. Other than that the highlight has been a harvest mouse, which was a real pleasant surprise. Keep up the good work with your footage!
