I feed crows during winter in my local park. They recognize me as soon as I enter and follow me around. Some even fly very close above my head and tap me with a wing.
Also they cache food they don't eat, they hide it, cover with leaves and make sure nobody is watching them, they act very casual. I am not sure if they remember the locations though.
Compared to ravens they have smaller head but I believe it is because they spend so much time near people (at least here in Europe you don't see ravens in cities, they are afraid,for historical reasons, of people and low in numbers) they get smarter and more crafty.

I can recommend a great book about corvids with beautiful illustrations: https://yalebooks.yale.edu/book/9780300122558/in-the-company...
