That is no fairytale creature perched on the crooked fence in a spooky story, it is areal crow or raven. These glossy black birds have starred in legends for centuries, from the ravens of Norse myth to the poem where a raven croaks a single gloomy word. But peel away the shadowy reputation and you find one of the sharpest minds in the animal kingdom, wrapped in feathers the color of midnight.  \nThose midnight feathers belong to a family called corvids, and telling the two apart is trickier than you might think. Ravens are the giants, roughly the size of a large hawk, while crows are noticeably smaller, closer to the size of a pigeon. Look at the tail when the bird flies overhead: a raven's tail comes to a wedgeshaped point, but a crow's spreads out like an open fan. Listen, too, because a crow gives a sharp, clear\"caw\" while a raven answers with a deep, croaking \"gronk\" that seems to rumble from its chest.  \nThat rumbling voice hides a brain that scientists rank among the smartest on the planet. Researchers have found that some crows and ravens can plan for the future and even understand that a hidden object still exists, a skill many human toddlers are still learning. In one famous experiment in a science lab at the University of Oxford, a crow from New Caledonia bent a straight piece of wire into a hook to fish a snack out of a tube. No one taught the bird that trick, it invented the tool on its own, something only a handful of animals can do.  \nMaking tools is impressive, but remembering your face may be the eeriest talent of all. In a study at the University of Washington, researchers wore masks while capturing wild crows, and years later the birds still scolded and dive-bombed anyone wearing that same mask. Stranger still, crows that had never been captured joined the mob, meaning the original birds had somehow passed the warning along to others. If you are ever kind to a neighborhood crow, it may recognize you and, some people report, leave small shiny gifts in return.  \nThose gifts help explain why humans have woven these birds into stories for  \nthousands of years. In Norse legend, people told a tale that two ravens named Huginn and Muninn, whose names mean \"thought\" and \"memory,\" flew across the world each day and whispered the news to the god Odin. Because the birds gather at dusk, feed on what other creatures leave behind, and seem to watch us with knowing eyes, many cultures linked them to mystery and the unknown. That reputation is exactly why they show up perched in the artwork and decorations you see every October.  \nSo the next time a crow eyes you from a Halloween lawn display, remember there is a real genius behind the spooky costume. It might be memorizing your face, sizing up a puzzle, or bending a twig into a tool while you walk past. Crows have even been seen dropping hard nuts onto crosswalks so passing cars crack them open, then waiting for the light to change before swooping down to eat. For a bird that legends painted as a  \nsymbol of doom, that is a surprisingly bright way to grab a snack.  \nCrows and  \nRavens  \nName:  \n\n| Solve each problem.\u003Cbr>Use the article to answer the question.\u003Cbr>1) According to the passage, how can you tell a raven from a crow by its tail in flight?\u003Cbr>A.
