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

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.
