Threatened species could be taught to avoid predators: Study
An Australia-based study on native burrowing bettongs, also referred to as rat-kangaroos, has shown that exposing threatened animals to small numbers of predators in the wild improves their evasive behaviours. Researchers introduced 352 bettongs into a 26-square-km area with four cats. During the 18-month study, they observed increased hiding behaviour and awareness in the bettongs while feeding.
