They not only make and use tools, such as bending wire into hooks to retrieve bugs from tree holes, using stones to crack open nuts, and even placing nuts by the roadside to be crushed by cars before eating.
They also possess complex logic and memory, being able to remember human faces, distinguish between good and bad intentions, and plan for the future, such as hiding food in advance, disguising the location of hidden food to confuse their peers, and even understand cause and effect.
If owls are the huskies among birds, then crows are the border collies.
Crows originally should not be on the menu of macaques, but macaques, lacking moral integrity, would raid crow nests, steal eggs, and attack fledglings.
In terms of intelligence, crows and monkeys are pretty much on par, but obviously, the monkeys underestimated the crows' determination for revenge. For a long time afterward, the crows launched attacks on the monkeys.
