From the trail cam footage, it looks as if we’ve got a pair of wrens roosting. Last year when there was snow on the ground we estimated somewhere between 7 and 11 wrens roosting, all in the nestbox on the left. The nestboxes don’t connect on the inside.
As they settled down there was a lot of flitting between all three holes and the pair seemed particularly interested in the middle hole but they eventually settled on the hole on the left to roost.
The last we see of the wrens on the trail cam is at 7.33 am when one of the wrens appears in the left hand hole and appears to be preparing to leave.
The blue tit arrives an hour later and makes a careful inspection of the first two nest holes, but doesn’t go in.
