Its both. Crows and Ravens remember everything. Ravens are a bit smarter as they use mimicry and false alarms to squirrels so they can swoop in and steal the squirrels food.

0:56 not both of them looking at you Aiden 😂😂😂

My roommates and I had a crow when I was at university. I was the only one that went to school, they just worked. But that crow would follow me to every different subject buildings until I was done for the day, then it would follow me back home (We only lived a block off the campus area. We had a had a box on the open deck we had for it to live in, so it was free to go whenever it wanted. It would also follow use when we walked to the bars at night. We fed it almost everything. I did leave trinkets like the little girl got in this video.

Primates, elephants, whales, ravens and pigs.  Top five smartest in no particular order.
