You can call me crazy, but I had no idea that something like pigeon spikes actually exist. To be honest, I had absolutely no clue pigeons are such a pest anyway.
These days, being jobless and staying at home makes me think a lot about all those hundreds of various topics and things that I simply had no time to study or pay attention to. Today I read a lot about the effectiveness of pigeon spikes when used to repel pigeons from landing on buildings, churches, etc.
It's simply amazing how these birds that are considered the birds of freedom can produce so much harm, that's why I want you guys to watch this short YouTube video. It's pretty freaking amazing and disgusting at the same time, but is definitely worth the time.
