Three were collecting acorns from under a nearby tree and taking them into a hole under the leaf litter.
No interactions present.
On the second picture the collar on the neck looks like it joins up. Made me wonder if it is a yellow necked mouse.
I also took a short video of it grooming (which is at http://patchsnaps.blogspot.com/) and I tend to think that the collared effect is just an optical illusion.
I have added a video-grab shot of the mouse grooming which may be of help.
At the end of your vid it faces the camera and that collar does go all the way around. I would be inclined to think that is a YN.
Very cute mouse/mice and I agree the end of the video and the second photo show a band of brown from shoulder to shoulder hence yellow-necked. Quite an unusual spot - well done for capturing it on camera!

After studying the video again, I think you are right. The collar appears to meet and is broad enough to suggest Yellow-necked.
I totally agree - yellow necked mouse. - you can tell from picture 2 that the band is uninterrupted.
