Weeeeeird.

When we moved in, tail end of 1987, front was wall-to-wall & edge-to-edge grass.
The back was ditto, the monotony broken by Privet to the left, Beech to the right and Leylandii dead ahead: with, I think, all the grass which had been cut since building in 1961-2 in the far, right, corner.
Every bit of vegetation travelled in via car, including the late lamented 12" diameter trunked Betula utilis var. jacquemontii -West Himalayan birch.
This little critter, however, has snuck in under the "RAdio Detection And Ranging" system. Can't see any in either LHS or RHS neighbours.
