Crows are known for their intelligence, and have even been seen sledding using a plastic lid.

Now, the BBC has again shown that these smart birds are not to be underestimated on their program The Problem Solvers.

Dr Alex Taylor trains wild birds, and has shocked the science world with one specific Crow, named 007.

He tested 007 with a puzzle that consists of eight separate stages that must be completed in an precise order to obtain the treat at the end.
