There are naughty people called "fly tippers" who tip their rubbish on the edge of fen droves. It's illegal, of course, but it's hard to catch the blighters. I hate their selfish antisocial ways, but I was grateful to whoever tipped an old bedside cabinet on the footpath near where I live. The shell of it was the perfect size for an indoor Barn Owl box; it just needed to have a front and a base added to it.
The main drawer of the cabinet was also pressed into service with the addition of a back and a half-front, turning it into a Kestrel box (or possibly Stock Dove, whichever finds it first).
Today, David H, bless his cotton socks, gave me a hand to check two Long-eared Owl nest baskets that we had put up in NineAcre Wood last winter. Result: one empty, the other used by pigeons. Never mind, it's all speculative stuff. We also improved the security of a Little Owl nestbox by strapping it to the trunk of the tree.
And as a reward for our virtuous deeds, we were treated to excellent views of a gorgeous adult male Hen Harrier quartering North Fen.
God's in His Heaven,
All's right with the World.
Including some fly tippers.
