Crows understand Analogies

I like crows – they are magnificent birds until they open their beaks to let out a cacophony of caws. I like their shiny black feathers and their cute waddled swaying gait.

Crows are smart enough to distinguish between solid and hollow objects, are good at crafting and using tools, and what is more, can exhibit analogical thinking – something that was known only of humans and some monkeys (apes in particular).
