Burrowing creatures

The weekend doesn’t seem to have incorporated a great deal of daylight. Darkness, yes. Drizzle, yes. Rain, yes. And, at the Brickworks, mud. Mud, mud and more mud.

Views of the mud and murk at Bovingdon Brickworks today

As I walked through the mudow (that’s mud/meadow) (top left photo), a Song Thrush was singing in the trees to my right. A crystal clear, full-bodied melody of flutes and whistles, projected far and wide. It was better than sunshine. Up ahead of me, I spotted another 5 Song Thrushes together in a bush and, behind me, 2 more. There were at least 10 around the site. A flock of 40+ Goldfinches were feeding on thistle seeds, along with Chaffinches and a mix of Tits. Last week, I’d counted at least 20 Blackbirds within the scrub and, easily, 5 Green Woodpeckers. 3 Jays gave me glimpses of white rumps and a couple of Fieldfare swapped one tree for another. Towards the end of my squelching, I chanced upon a Robin quietly singing his pretty sub-song. It was as though he was testing the air to see if anyone was listening. Delicate yet sure and another ray of sunshine.

The main reason for my visit today was to retrieve the trail camera, which I’d set up over night. We were keen to discover what had created the two burrows found by David K a few weeks back. The entrance holes are approx 40-45mm diameter and excavated soil is piled up outside like a larva flow.



The camera trap results weren’t bad. I’ve put together 60 seconds worth from the 120+, 14 second clips that were captured. All occurred between 21:00 and 00:00 yesterday. I’d put down a few peanuts and sunflower hearts to entice little creatures to do more than dash, dart and streak across screen.



So, the mystery homemaker is definitely a mouse and we have at least 2 living in this burrow. They’re likely Wood Mice (Apodemus sylvaticus) but I think only daytime footage would clinch it (fur colour). I confess, I had hoped for Bank Voles but, even so, it’s been useful to get some experience with the trail camera and learn more about the habits of these little Wood Mice.
