We used sonic cannons when I worked in vineyards, as birds would eat the grapes just as they were nearing harvest. Worked at first, but birds quickly became accustomed to them, even perching on them.
On a flat roof, you might try remote-control model cars/trucks to chase birds; no FAA license needed there. The New York State IPM program recently reported some success using them---and also this fella---for chasing geese off of playing fields: [cid:image002.jpg@01D6A7AB.40A1A570] I think the advantage of the air dancer over other scare tactics is its size and the randomness of its movements. Birds quickly adapt to static scare techniques. I’m sure the nearest used car lot can tell you where to get one. :-) Dan Wixted Pesticide Management Education Program (PMEP) Cornell University Ph (607) 255-7525 525 Tower Road FAX (607) 255-3075 CALS Surge Facility psep.cce.cornell.edu<http://psep.cce.cornell.edu/> Ithaca, NY 14853 dj...@cornell.edu<mailto:dj...@cornell.edu> From: pestlist@googlegroups.com <pestlist@googlegroups.com> On Behalf Of Alan P Van Dyke Sent: Wednesday, October 21, 2020 12:54 PM To: pestlist@googlegroups.com Subject: Re: [PestList] Bird scarers Many years ago the University of Texas at Austin employed sonic cannons to scare off grackles from campus. It was a pretty effective tactic, but neighboring areas were a little disconcerted by what sounded like a lot of gunfire was going off nearby.

Seems to work well. Again, not sure about their use in urban areas. Those sonic boom bird scarers are a menace. There is a farmer using one in our area and it sounds like a huge explosion that can be heard for miles around, especially in the early morning hours! There is also a new product on the market that poisons birds temporarily, causing them to convulse and scare other birds away by their cries of danger and distress. Supposedly 'does not cause pain or pose a threat to other species'. Sounds horrific and cruel, but it is actually on the market. How much trouble our feathered friends can cause!!

They use acoustic scarers to deter birds - but instead of high frequency they use lower frequency "booms" - might not be super practical for central London - but the Aviation Industry might have some good leads on deterring birds.

It has been suggested that the birds see it as a ‘lake’ and we have never had success with things like shock systems or brining a hawk around the site Our pest control company has recommended high frequency acoustic scarers I don’t have any experience of them so have any of you used them and is it worth the investment?
