Light protection to deter birds at a vineyard - GIF

[BuffaloJohn]

I looked into this and I found that the published success rate was only about 70%.

It is a green laser, so I decided to get a gree laser pointer to see if I could tell if there was any effect I could determine. I was able to hide well enough that birds would land and then I would fire up the laser and focus on the bird's head. I was unable to see any effect. The birds didn't even move to avoid the light and when someone with me looked through a spotting scope, they saw I was able to hold the spot on the bird's eye for seconds. I call BS on this. With a powerful enough laser that kills the birds - maybe...
