Crows use multitools, but do they plan ahead? - life - 05 August 2009 - New Scientist
excerpt from above:

Tool-toting New Caledonian crows may be smart, but are they schemers?
The cunning birds can sculpt twigs into hooks and wield multiple tools in succession to obtain an otherwise unreachable snack. This kind of behaviour has prompted some scientists to conclude that the birds plan their actions ahead of time to achieve a goal.

However, new experiments led by Joanna Wimpenny and Alex Kacelnik at the University of Oxford cast doubt on that conclusion.
