Kea could detect 1080 bait by how it looks

A discovery that kea might be able to detect toxic 1080 bait by how it looks, could be a breakthrough in teaching them not to eat it. The controversial poison is used widely to control pests on conservation land, but it also kills non-targeted animals and birds - including, sometimes, the endangered kea. New research shows that an additive that makes it shiny, might be the tool needed to teach the curious alpine parrots to avoid the toxic pellets. Tracy Neal reports.
