I have a problem with pigeons waking me in the early hours of the morning and I want to be able to scare them away from the comfort of my own bed with a press of a button.
There are a number of trees surrounding my garden and the pigeons will land in one of them from around 5am and call loudly to each other across the area. Ideally, I want something small that I can place in a tree and that won't need maintenance too often.
The local population of pigeons know that I am to be feared, so I only have to make the merest noise to scare them away - I also don't want a noise so load that it will disturb my neighbours.
So, I've assumed that it will be electronic - but if you have something more creative, please suggest it.
I'm not necessarily looking for a cheap solution - but it does have to be minimal effort, so no suggestions that start, "Using an Arduino..." please.
