I live in Buenos Aires and here doves are a Biblical plague. I once purchased an owl decoy but doves just ignored it – and maybe even laugh at it – . In fact the only one scared with the owl decoy was me a drunk night in the backyard.
Anyway, now I made this Doves Repellent using that old owl decoy, a Raspberry Pi2 and some other things. The device will detect doves’ movement and it will trigger scary owl and hawk predator sounds. Owl decoy eyes will also turn red. Not sure if red eyes scares doves but the zombie effect is pretty cool.
