In spooky stories, crows and ravens show up as messengers of mystery, their harsh calls echoing through the fog. But here's the real puzzle: these birds are far more clever than any ghost tale gives them credit for. In fact, they are among the smartest animals on the whole planet.  \nThat cleverness shows up the moment one of these birds meets a problem it cannot solve with its beak alone. Scientists have watched crows bend wire into hooks to fish food out of tubes, which means they can actually make tools, not just use them. Very few animals besides humans and some apes can do that, so the fact that a bird can is a real surprise. One New Caledonian crow even solved an eight-step puzzle to reach a snack, working through it like a tiny feathered detective.  \nSolving puzzles is impressive, but remembering the people around them may be even stranger. Researchers at the University of Washington once wore masks while catching wild crows, and the birds remembered those exact faces for years afterward. When a masked scientist walked by later, the crows would scold and dive at that person, even birds that had never been caught themselves. That means the crows had passed the warning along, telling their neighbors and young which human to avoid.  \nIf crows can gossip about faces, it makes sense that they gather in big, noisy crowds too. A group of crows is even called a \"murder,\" a spooky old name that helped tie these birds to Halloween in the first place. On cold nights, thousands of them may roost together in one place, filling the air with a chorus of caws. People long ago saw those dark swarms and told stories that the birds carried messages between our world and another.  \nSo how can you tell a crow from a raven when both look like shadows with wings? Size is the biggest clue, since a raven is roughly the size of a hawk while a crow is closer to a pigeon. Look at the tail in flight too: a raven's spreads into a wedge or diamond, but a crow's opens like a fan. Listen, and you'll hear the final difference, because a crow gives a sharp \"caw\" while a raven answers with a deep, croaking\"gronk\" that sounds almost like a growl.  \nCrows and  \nRavens  \nName:  \n\n| Solve each problem.\u003Cbr>Use the article to answer the question.\u003Cbr>1) What is the main idea the whole passage keeps returning to?\u003Cbr>A.
