We have a grassy (this time of year) bank at the front of our house and recently two holes have appeared near each other.
The larger of the two holes is about 7cm in diameter and as you can see, quite a lot of excavation work has been carried out.
The smaller one, around 5cm in diameter.
Being so close together, I suspect they both lead to the same place. I’m really not sure what has built these, possibly a Field Mouse but the only way to find out is to put the Bushnell NatureView camera there and see what happens during the day and night.
Hopefully, will have some video footage to share soon.
