The Indonesian Goffins cockatoo, also known as the Tanimbar corella,(and Cacatua goffiniana has recently been exposed as an inveterate tool user and problem solver, so we are please d to see this paper today. Hopefully, more amazing animal behaviour will be forthcoming as we finally realise just what intelligence exists outside our own.Goffins cockatoo image; Credit: © Sam at photos8.com
The parrots and crows stand out as bird brains who can compete with even the primates at masterminding their environment. When it comes to unfamiliar materials that do not exist in their environment, then the competition heats up. Goffins cockatoos are Near-Threatened parrots from Indonesia belonging to a group of 11 cockatoo and corella species. The reason for their situation is also their saviour because the main hope of avoiding near-extinction is in the great number of captured birds being bred for sale.
At the Universities of Vienna, Austria, Manchester and Oxford, UK, Alice MI.Auersperg, Stefan Borasinski, Isabelle Laumer and Alex Kacelnik have been investigating how the cockatoos utilise tools they adapt from different materials, publishing today
The bird in nature doesnt make nests and forage without tools in a very general way, making the research more valuable than established research on crows for estimating innovative capabilities in the species in captivity.
Figaro began the whole research himself by using larch splinters to rake food from behind a grid. He is a bird, of course, so 3 more males were also shown to be successful when
asked to emulate his feats. They had tool use demonstrated, and then proceeded to copy, with one individual getting as far as Figaro, in making his own splint. Later experiments prove that elongation of the tool was one aspect the birds successfully attempted, making cardboard, beech twigs or larch wood more effective as tools.
The interesting point about this research is the way in which fast and flexible skill transfer was possible. Even sculpting was employed by the bird subjects to achieve a suitable tool for use. The cardboard rakers in particular showed in most cases that the animals could manufacture a tool of the required length (as well as width). The larch wood split naturally into strips that were sometimes too long for the job concerned. Even more significantly, the birds are capable of unpicking a 5-part lock mechanism, so we can see this research taken much further!
We have lots of stuff on tool using by the animals we mention here, but this is the fabled African Grey for a lesson on avian learning: – we believe these brainboxes should really be teaching us.
