Molebusters

In the opening pages of The Wind in the Willows, the Mole ‘scraped and scratched and scrabbled and scrooged’ his way to the surface. This winter there’s been a lot of scrabbling and scrooging around the lakes at Nostell Priory. Molehills have been popping up on verges, path edges and even under park benches, many of them just the size of a pudding basin but there are several that are the diameter of a dustbin lid, containing two bucketfuls or more of soil.

We’ve seen fieldfares using molehills as vantage points on the open parkland. Around the lakes, the resident robins often perch on them; they’ll give one that has been freshly excavated a close examination, picking out any food items (presumably invertebrates) that might have been brought to the surface.

Useful as they might be to some of the local birds, the mounds will present an obstacle when mowing starts again in the spring, so now is the time to rake them out. The freshly turned soil can serve as a mulch, bringing minerals back to the surface.

For regular-sized molehills a little footwork is all that is needed but for the mole-mountains there’s a garden power tool that can help. Leaf blowers can be eight times faster than traditional raking and sweeping and this morning one of the gardeners is using a powerful leaf blower to spread the earth of a mound over a lakeside verge. Noisy but effective!

Mole Map

Molehill

As it was directly under the fat ball feeder which hangs from the washing line we did at first consider that it might be a brown rat digging a bolt hole as close as possible to a source of food but no exit holes ever appeared so this is a subterranean creature; it must be a mole. At the moment there are plenty of molehills just like this on grass verges and alongside the woodland path.

In our back garden this afternoon the grey male sparrowhawk zooms into the bottom of the hedge. Twenty or thirty seconds later he pops up again from our neighbour’s side arcing over so swiftly that for a moment he’s flying upside down.

Emerging unsuccessfully again from our neighbour’s side he leaves the hedge with nothing, sitting for a few minutes on next door’s sumac. If it wasn’t being anthropomorphic, I’d say that there was distinct look of grumpiness in his hunched silhouette.

He flies over the corner of the meadow to the wood, putting up a flock of goldfinches and sending the wood pigeons into clattering panic from the ivy-covered ash trees.

With the snow gone and the pheasants and wood pigeons trampling the border beneath the bird feeder I was beginning to think that all mole activity had ceased. Late this afternoon the mole started re-excavating its tunnel system and we watched as it piled up the earth by the edge of the lawn, obviously coming very near the surface but never once showing itself.
