Sparrow trap / Trampa para gorriones

Hi cannabis lovers. This year I'm going to get serious about sparrows. They have been hanging around the terrace for days now and have eaten two cannabis plants.

I am going to make traps for sparrows without killing them. At the moment I only intend to scare them to death so that they don't come back. If they don't respect the Cannabis plants I don't want them on the terrace. If this model works I will make another one and if it doesn't work I will try anothe design.

I hope you liked it and have a great day.
