After a few years of feeding outdoor birds, we often get nuisance birds such as crows and the odd pigeon, which raid the feeders.
Keeping the crows off the hanging feeders turned out be quite simple in the end - Just attach two dome-shaped wire hanging baskets around the feeder, which lets the small birds at the feeder, while keeping out the crows.
However, I’ve one more feeder which is suction-cupped to the window and it seems like one pigeon has taken a liking for it, raiding all the food within minutes.
One idea I thought of that should discourage the pigeon from coming back is to set up a remote control water squirter or sprayer aimed at the feeder and active it using a remote control once the pigeon is spotted on the feeder.
After thinking it would be just a matter of looking up eBay, Amazon, etc. I can’t find any such thing out there. There are plenty of motion-activated squirters such as for protecting ponds, seedlings, etc., but nothing that I can find that can remote-activated.
Does anyone know of a device where you can press the button on a remote control and it briefly shoots a jet of water like a toy water pistol?
