Prof Tim Noakes Posted June 12, 2019 Share Posted June 12, 2019 I don't know why they do this - crows and rooks are better known for this kind of behaviour but usually attack rubber seals and wiper blades etc. Any thoughts on the best, magpie unfriendly, alternative to silicone for sealing around PVC frames? (The rubber seals around the glass are ignored by the magpies although they peck the glass occasionally.) Thanks in advance. Link to comment Share on other sites More sharing options...

Temp Posted June 12, 2019 Share Posted June 12, 2019 I think if its applied well they can't get it out. Link to comment Share on other sites More sharing options...
Jilly Posted June 12, 2019 Share Posted June 12, 2019 Hi there, corvids are exceptionally intelligent, and may have initially been rewarded by pecking insects and are now finding this to be enormous fun! Apparently aluminium ammonium sulphate can be used as a bitter tasting deterrent. I assume they were initially drawn to the windows by their reflection, its very common for birds to get fixated around mating time as they become territorial, and this may have something to do with it. If this is part of it and you can stop the reflections for a while it may extinguish the behaviour. I know a bird behaviour expert on FB, so will ask there for more suggestions. Sorry, I know nothing about silicone.... 1 Link to comment Share on other sites More sharing options...

Prof Tim Noakes Posted June 13, 2019 Author Share Posted June 13, 2019 I've come across some (quite old) advice that polysulphide sealant isn't liked by birds. Polysulphide's largely fallen out of use now though - any thoughts on magpies and polysulphide's more modern replacements like polyurethane, modified and hybrid polymers and modified silane? (Polysulphide sealant is still available.) Link to comment Share on other sites More sharing options...
