Question
2 Don’t worry. I’m speaking not of any human family, but of the bird family Corvidae, and particularly the crows and ravens in the clan Corvus. Like most members of that genus—which in North America also includes magpies, nutcrackers and jays—crows and ravens are sturdy, stout-beaked, long-legged birds with powerful wings. They also have something of an attitude, which can vary from aloof to in-your-face.
3 You can forgive them for their superior airs1 though, when you consider their resumes. Crows and ravens are the stuff of legend; for centuries, they have been revered and reviled, fawned over and feared by humans. Shakespeare wrote them into his plays, Thoreau into his musings2, Poe into his horror tales. Shrines have been built to them; songs sung; chants chanted. Oh—and one more thing: Crows and ravens are the eggheads of the bird world and thus the darlings of avian science. With the arguable exception of parrots, they’re the smartest winged species on the planet. They’ve even outperformed monkeys in some psychological tests. Truth be told, they’ve outsmarted many a human, too.
THEY’RE EVERYWHERE
4 Some 40-plus species of crows and ravens inhabit the skies worldwide over virtually every terrain, from desert to tropics to tundra. In the contiguous United States, the American crow (Corvus brachyrhynchos) is easily the most common. Three other crows claim American territory: The slightly smaller fish crow (C. ossifragus) ranges along the East Coast and through the Gulf States east of Texas; the Northwestern crow (C. caurinus) occupies the Pacific Seacoast from upper British Columbia to the northwestern tip of Washington; and the Mexican or Tamaulipas crow (C. imparatus) calls southernmost Texas its home.
5 Geographically, the crow’s larger cousin, the common raven (C. corax), is more broadly distributed. Its overall range encompasses almost all of Canada and Alaska; most of the western United States; and New England and the Appalachian mountains. In reality, though, the common raven is less common across its range as a whole, except in higher elevations. Like hawks and eagles, ravens prefer high places from which to search for food.

A raven steals a ski cap
6 Although crows and ravens apparently have no trouble telling one another apart, humans have a harder time discerning the distinctions. Size would seem to matter, since an average raven is far larger (2 to 4 pounds, with a wingspan up to 4 feet) than a correspondingly average crow (1 to 1½ pounds, with a wingspan up to 3 feet). But if you judge strictly by size, you can easily mistake a small raven for a large crow or vice versa.
7 Finally, listen to the bird’s calls. The crow’s trademark caw caw doesn’t remotely resemble the raven’s characteristic utterance, a deep guttural crrroak or naaaaahk.
SPEAKING OF INTELLIGENCE
8 That crows and ravens are classified as songbirds may come as a surprise, but it is the presence of a voice box, or syrinx, rather than talent for melody that qualifies them. They use their vocal equipment to communicate with a large vocabulary of expressive calls for courting, gathering, warning and more. Ornithologists3 have identified as many as 24 crow calls and up to 64 distinct raven vocalizations.
9 But it’s brainpower, not bravado vocals, that really sets crows and ravens apart from other animals. They have the largest cerebral hemispheres, relative to body size, of any birds—the raven’s brain is the same size in relation to its body as a chimpanzee’s. More significantly, crows and ravens apply their brainpower; they learn quickly, solve problems and store knowledge in long-term memories.
10 Furthermore, crows and ravens understand cause and effect. In the South Pacific, New Caledonian crows sculpt twigs into hooked probes that they use to pry out otherwise inaccessible grubs—they make their own “crowbars.” The same crows nip the edges of rigid leaves to create saw-like teeth, then shove barbed tools beneath leaf litter to spear prey. They also carry their tools with them on foraging4 expeditions, and store them for later use.
11 Stories abound of crows or ravens dropping nuts or clam shells onto highways and other hard surfaces to break them open. In Japan, crows are reported to have taken the strategy a step further by placing nuts in front of the tires of cars stopped at red lights.

12 Scientific research confirms much of the anecdotal5 evidence. In one study of captive birds, scientist Bernd Heinrich dangled bits of meat from the end of a 2-foot-long string tied to a perch. He then watched his test subjects—first a pair of American crows, and later five common ravens—attempt to bring home the bacon (in this case, it was actually salami). The crows tried flying at the food, then tugged at the string a few times, but gave up within 15 minutes. Time to study the situation didn’t help; after 30 days, they still hadn’t solved the problem. The ravens spent a few hours glancing at the puzzle, as if weighing the possibilities. Then one bird flew to the perch, hoisted a length of string up with its beak, stepped on the loop, pulled up another length, stepped on that loop, and so on until it had reeled in the food. Ultimately, three more ravens also solved the problem. Two improved on the technique by simply grabbing the string and side-stepping along the perch.
13 None of this would surprise ice fishermen in Finland, where hooded crows use the same pull-step-pull-step method to haul in fish on abandoned baited lines.
