Would it work for windscreen wipers too?

A trial using a non-toxic repellant that makes keas feel queasy might deter them from attacking sheep.

If it also works for windscreen wiper they could be on to a winner with people using South Island ski field car parks or tramping in the high country.

Keas are cheeky birds which entertain visitors? But they do a lot of damage to  the rubber on windscreen wipers and around the windows of vehicles and many’s the tramper who has been woken by one or more keas pecking holes in their tents.

UPDATE: TV3 reports researchers are looking at whether the repellant could be used on tents and cars too.
