Crows are considered among the most intelligent of all animals (see here and here for proof). In this video, a crow is seen lobbying a group of humans for some water on a hot and humid day. It takes a while but the bird is ultimately successful, replenishing himself before taking flight.

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.
