Crows and other intelligent birds can use tools and mourn the dead. I remember a video where crows used a crosswalk to open nuts, eating them when the cars stopped.
Crows will also remember a face and tend to show gratitude to you by leaving you shiny things if you feed them or help them.
They'll also hold a grudge, avoiding or attacking you if you fuck with them. Somehow they can pass on the word to other crows too.

Magpies, a highly related species of corvid, can recognize itself in a mirror.
