Funniest places birds nest

[AceofClubs]

I have known a blackbird nest in the large leaf of my fathers rhubarb patch years ago,also a wren nested in a Snap on Tools peaked cap in an old greenhouse.Anymore unusual places anyone has come across?

This morning I saw a little blue tit bobbing in and out of an empty burglar alarm casing with what looked like bits of grass in its beak, so I assume she was making a nest.

Robin, in one of the ponies hay net! (took me a whole day to realise pony was not touching hay). I simply put up another net and Robin, fledged her chicks with no problem, with the help of her very large protector!!!
