Light protection to deter birds at a vineyard - GIF

[neilbourjaily]

That's a long way from the cannons and traps that were the go to for vineyard bird control. You had to wait to put the cannons in because the birds would get used to them. *BANG*! and they'd leap into the air and settle back on their snacks. Typically, they'd peck a grape, suck some juice and peck another eventually ruining the whole bunch. Some growers installed traps, just a downward tapered opening to narrow to fly up through. Many growers would just cage them and relocate them. I did see one grower,an early promoter of organics in the 1980s, in the cage with a tennis racket swinging like a madman. It was very entertaining.
