Crows can both use and construct tools. Crows are among the smartest animals, almost as smart as primates. Crows in Israel have learned to use bread crumbs to bait fish. One species drops nuts into streets and waits for cars to run over and crush open the nut. A species in Australia learned how to eat a poisonous toad by flipping it over and violently pecking at it's throat.
Crows make a lot of different vocalizations. They have been found to respond to calls from other species. My friend Sophia told me that one crow learned how to sing a Lady Gaga song, and sang it better than Lady Gaga too.
Crows play mid air games of chicken to determine pecking order.
The oldest crow in captivity lived to be 59. The oldest, wild, American crown found was 30.
