Both are highly intelligent, though ravens generally perform slightly better in some cognitive tests.

While not as skilled as parrots, some crows can mimic human speech and other sounds.

What Is The IQ Of A Crow?

Crows aren't just smart birds. They remember human faces, teach their offspring about dangerous people, hold elaborate gatherings around their dead, use tools, solve puzzles, and even appear to give gifts to humans.

Crows can remember the faces of humans and even other birds

The Weirdest Crow Facts

Crows Remember Human Faces For Years
Crows can recognize individual people and remember those they consider threatening for years. Researchers in Seattle wore a frightening "caveman mask" while trapping crows. Years later, crows still recognized and scolded people wearing that same mask, even birds that had never seen the original event had learned to dislike it._[5]
Crows Can Teach Their Offspring Who To Hate
Young crows learn from older birds which humans should be avoided, allowing information about threats to spread across generations._[2]
Crows Appear To Hold Funerals
When a crow dies, nearby crows often gather around the body in what scientists sometimes call a "crow funeral." These gatherings help crows learn about potential dangers in their environment. By observing death, they may avoid similar threats in the future._[3]
Crows Use Traffic Lights
In urban environments, crows have learned to drop walnuts onto roads and wait for cars to crack them open. They retrieve the nuts safely when traffic stops at red lights._[18]
Crows Have Regional Dialects
Crow calls vary by region, creating local "accents" that help birds communicate within their communities._[18]
Crows Can Mimic Sounds
Crows have a complex communication system and make a wide range of calls, caws, and croaks. They can mimic the sounds of other animals, and they even have their own dialects._[15]
Crows Have More Than 250 Different Vocalizations
Scientists have documented hundreds of distinct crow sounds used for communication._[18]
Crows Have Been Seen Giving Gifts To Humans

Crows Will "Mob" Larger Predators
When threatened, crows will aggressively harass predators, such as owls and hawks, and will call in other crows to join the attack._[11]
Some Crows Perform "Anting"
Crows occasionally rub ants onto their feathers, possibly using the insects' chemical defenses to help control parasites._[18]

"Anting" is still a mystery, but most scientists believe that the ants' secretions help control feather mites and other parasites
