I look forward to seeing what sort of water weapon you come up with.
Grey squirrels are our biggest problem. And cats. :a
And worst of all, a general lack of birds these days.
The fields used to have hundreds of Golden Plovers & Lapwings in the winter, accompanied by Merlin, Peregrines, Meadow Pipits and Linnets (and one year a Snow Bunting!). In the garden there would be dozens of Greenfinches, with occasional but regular visits from Siskins, Blackcaps, Brambling & Reed Buntings.
There was even a resident flock of 50+ Tree Sparrows, but they disappeared practically overnight 20 years ago (went away for a fortnight in June 1995 & haven’t seen a single one since :().
But these days even the Greenfinches & Starlings are rather scarce.
And now I come to think about it, I haven’t seen or heard a Yellowhammer for several years.
On the up side Red Kites have moved into the area - I caught a brief glimse of one a couple of months ago and my sister says she has seen them several times. But I would much rather have some of the old common species back.
