I have been breeding pigeons for many years now. Most of my friends do not like them though, and i can understand it.
Especially if you have your own garden and want to protect your crops, it is really important to invest into some sort of bird repellent system.
The easiest way is to buy bird netting, but of course, there are more sophisticated ways to scare away pidgeons, seagulls and other “pests”.
From ultrasonic systems, to gels, to spikes, to scare tape – In the end, you have to decide.
I can only help you make the right decision.
Thanks, and good luck!
