Stability of bird repellents used to protect kea (Nestor notabilis) during aerial 1080 cereal operations
Aerial poisoning with cereal bait containing 1080 toxin is known to pose a risk to the kea (Nestor notabilis), an endemic New Zealand mountain parrot. For a bird repellent to protect kea during such poisoning operations, it must be effective in bait for 4–12 weeks after the bait is manufactured, as this is when most aerial 1080 cereal operations take place. Two bird repellents have been shown to be effective with captive kea, d-pulegone and 9,10-anthraquinone.
