Navigating a tool end in a specific direction : stick - tool use in kea ( Nestor notabilis ) Alice

چکیده
This study depicts how captive kea, New Zealand parrots, which are not known to use tools in the wild, employ a stick-tool to retrieve a food reward after receiving demonstration trials. Four out of six animals succeeded in doing so despite physical (beak curvature) and ecological (no stick-like materials used during nest construction) constraints when handling elongated objects. We further demonstrate that the same animals can thereafter direct the functional end of a stick-tool into a desired direction, aiming at a positive option while avoiding a negative one.

متن کاملKea ( Nestor notabilis ) consider spatial relationships between objects in the support problem Alice
The ‘Support Problem’ is a benchmark test to investigate the understanding of spatial relationships between objects. We tested kea parrots’ performance in a paradigm that has previously been studied in primates. Kea perform comparably well to tamarins when they are confronted with a choice between two support devices, one of which has a reward resting on it and the other slightly next to it, or...
