697 7 uncanny facts about crows

Speech Materals

Intelligence runs in the crow family, a diverse group of more than 120 bird species. And, as with most genera, crows and their relatives tend to be misunderstood.

Known as corvids,they are incredibly clever overall, with the largest brain-to-body-size ratios of any birds, but those in the genus Corvus tend to be especially brainy. This genus includes the crows, ravens, rooks and jackdaws, accounting for about a third of all corvid species. Many of these have a brain-to-body-size ratio you’d expect from an ape, not a bird. In fact, according to one study, “the crow brain is the same relative size as the chimpanzee brain.”

Humans have long recognized the craftiness of crows and ravens, as seen in centuries of folklore casting the birds as thieves, tricksters, problem solvers, wise advisors to gods or even deities themselves. Yet we also tend to stereotype these birds, overlooking many of their complexities to brand them as spooky, troublesome or outright nefarious. Fortunately, our appreciation of their intelligence has soared in recent years, thanks to research exploring what corvids can do with all that brainpower. Below is just a sampling of what we’ve learned about their mental and social lives, focusing mainly on crows but also including ravens and other relatives:

1. Crows have shrewd ways to get food.
2. Crows don’t just use tools; they also make them.
3. Crows can solve puzzles on par with human kids.
4. Crows hold funerals for their dead.
5. Crows gossip, hold grudges and know who you are.
6. Crows mate for life, but they’re also ‘monogamish.’
7. Young crows may stay home for a while to serve as ‘helpers.’
