- Mental Visualization: Crows can solve hidden-object puzzle by think the translation of water to raise a floating reinforcement.
- Future Planning: They often hoard nutrient in secure fix, retrieve not entirely where they hid point but also which type of nutrient spoilation fast.
- Multi-step Logic: Crow have successfully pilot puzzles necessitate respective sequential action, such as removing a peg before pushing a push.
💡 Line: While puppet use is most famous in New Caledonian mintage, common crows have been detect drop nuts on route to be cracked by passing vehicle tire.
