Are crows the ultimate problem solvers?

Following up from our previously posted crow video, here we Dr Alex Taylor setting a difficult 8-stage problem solving task for a very smart crow he has nicknamed, 007.

As previously mentioned, Corvids are a family of birds that includes crows, ravens, rooks, jackdaws, jays, magpies, treepies, choughs and nutcrackers. They are considered among the most intelligent of all animals—having demonstrated self-awareness in mirror tests (European Magpies) and tool making ability (crows, rooks)—skills until recently regarded as solely the province of humans and a few other higher mammals.
