A week ago, several birds appeared on the neighbor tree next door. Every day they started calling at midnight, but at a meeting. It felt like they were not the same bird and kept calling until more than five in the morning. It was really collapsed. Have you ever encountered this situation and how to solve it? It’s said on the Internet that a green laser can repel birds. I don’t know if it’s possible to buy a green laser pointer.
Crows are birds with good eyesight and usually don't like bright light. Therefore, it can be said that the laser pointer is effective as a countermeasure against crows. Among many color laser pointers, the "green laser pointer" is effective for crows. The green laser pointer that emits the strongest light is said to be the most terrifying color for birds. When buying a laser pointer as an anti-crow measure, it is best to choose a product with a green laser beam. Depending on the group, red lasers may be effective and green lasers may be effective, so it is best to use them correctly. Red laser pointers have become very cheap, but green high powered laser are more expensive. Nonetheless, considering that you will suffer from bird damage, this is a cheap purchase. As a warning, I think it’s a good idea to explain to the neighbor before using the laser pointer to repel it. Since the laser beam can reach a distance of 500 m or more, you need to be careful not to mischief or interrupt. Of course, you need to be careful not to irradiate people or cars. Do not cause blindness or traffic accidents.
