Otatara pest control efforts paying off




NUT CASE: Zealandia kaka, including 1-year-old Amy, eagerly await the challenges set for them by PhD student Julia Loepelt in order to claim their cashew reward.Zealandia's kaka are turning the notion of "bird brain" on its head.
The native parrots' intelligence is being put to the test by Victoria University PhD student Julia Loepelt.
Since January, the 28-year-old biologist from Germany has been giving the kaka a series of tasks to challenge them, with a tasty reward at the end.
"The tasks differ in what sort of cognitive abilities are needed to solve it, whether they have to memorise something or have to solve a novel problem," she said.
"You look at whether they are able to solve it, or how fast they solve it, or if they get faster."
