It's not unheard of around here to increase shot noise to solve the problem...

Love the sound of them as they use the telephone-pole as target, the phone line ties into the house and the ceiling becomes a speaker element. No recording. Woodpeckers run faster than 1 PPS, around 2 PPS or so I'd guess from memory. I was once asked by a friend, who lives a couple of km away, if I had a russian woodpecker on my backside. Knowing his ability to make minimalistic jokes, I quickly checked the Internet, understood and replied that he could probably see that better from his place. :) Cheers, Magnus On 04/22/2016 03:03 AM, Tom Van Baak wrote: Paul, If possible can you make an audio recording of a woodpecker attack?
