Pigeon proof????

It remains to be seen if this will really be pigeon proof. I’ve really missed the little birds since a group of pigeons, who seem to reside on a neighbouring windowsill, constantly badgered them while they were feeding. There have been none in the garden since Christmas Eve. I have been trying to protect the feeders I already have but have not succeeded. I’m hoping that this new invention, made today, will deter the pigeons and my little songbirds will return. Fingers crossed for success.
