Poncho, my smart 30 year old double yellow headed amazon parrot, uses one of his feathers to help scratch his head! He was not taught to do this, he figured it out on his own! He will also use other objects besides feathers for the same purpose, like pencils, straws, toys, etc. Of course my fingers are his favorite tool for grooming those hard to reach areas, but I am not available 24 hours/day, so he has learned to improvise :) To see more vids of Poncho check out this playlist: http://www.youtube.com/view_play_list...
be sure to watch this amazing video of betty the crow taking a straight wire and bending it to make a hook to retrieve a bucket of food: http://users.ox.ac.uk/~kgroup/tools/m... read the research on the webpage to fully appreciate the video!
Here are some definitions of tool use: Jane Goodall defines tool use as "the use of an external object as a functional extension of mouth or beak, hand or claw, in the attainment of an immediate goal."
John Alcock defines tool use as "the manipulation of an inanimate object, not internally manufactured, with the effect of improving the animal's efficiency in altering the form or position of some separate object."
Ben Beck defines tool use as "the external employment of an unattached environmental object to alter more efficiently the form, position, or condition of another object, another organism, or the user itself when the user holds or carries the tool during or just prior to use and is responsible for the proper and effective orientation of the tool."
