When we talk about intelligent animals, we often talk about dolphins, dogs, elephants, cats, apes, pigs, and monkeys.
But crows should make that list as well. Crows do nearly as well as ravens solving intelligence tests. But they also have an uncanny memory for human faces. They can remember if that particular person is a threat.
Crows have a good sense that every person is different, and know that they need to approach every person differently.
Scientists have long known that crows are exceedingly intelligent animals. But new research shows that these animals may be getting smarter and evolving.
