Hello everyone, I'm new here. Because I feed wild birds in my garden, my neighbour has mounted an electronic bird scaring device on the outside corner of her bedroom windowsill angled so that it is pointing directly over my fence into my garden. This device is meant to be an 'almost silent' device made by http://www.martleyelectronics.co.uk/silent-bird-scarer/64-mp1b-silent-bird-scarer.html" [Broken], and it works by playing different high frequency sounds in a loop. I can hear various whistling and whooshing noises, soft clicks and loud clicks (like someone is repeatedly clicking their fingers) The local authorities here can't act on it as a noise nuisance, but I'm advised by the manufacturer that the sound would be diverted from the birds by placing something between me and the sound. I would still be able to hear it though. Is there any reasonably simple way of deflecting the sound back to it's source, or disrupting it, or do I have to plant trees along my fence and wait years for them to grow? Thank you in advance if anyone can suggest anything that might help. I'm not technically a 'twitcher' as that is someone who goes everywhere to see a particular bird. I'm just a 'birder' who like watching birds and taking photos of them.
