Coyotes(丛林狼) used to live only in wide-open spaces of western prairies and deserts. They avoided forests, where wolves, their enemies, lived. But as forests were cleared to make room for farms and communities, coyotes started spreading east and west into they newly open territories.

Most coyotes are afraid  of people, so those living in cities have learned how to avoid being seen. Street-smart coyotes hunt for food between dusk and dawn, when few people are around. During the day, the animals rest in out-of-the-way spots. ”They ‘are trying to avoid people as best  as they can ,” says a scientist studying coyotes around Chicago, Illinois

City life suits coyotes in several ways. There are no enemies such as mountain lions ,wolves ,or hunters. City coyotes eat well, too. Parks yards and green spaces in cities provide habitat for a feast of favorite coyote foods ,including mice ,rats and  rabbits . Coyotes also eat lots of fruits , With plenty of natural food and no-predators (捕食性动物), coyotes in urban areas are healthier, live longer and raise larger families than their country cousins.

Unfortunately, some city coyotes lose their fear of humans. They find tasty garbage of pet food outside homes. They notice that people ignore them instead of chasing them away. Some humans even feed coyotes on purpose, thinking it’s an act of kindness. Actually, it’s a serious mistake.

Coyotes that become comfortable around people and learn to associate buildings and yards with food are the ones that get into trouble. Some coyotes attack pets in yards. Sometimes a coyote may even chase or bite in a human. An animal that behaves in these ways must be removed by wildlife officials.

It’s people that change coyotes’ behavior. But we’re also the ones who can help them be good neighbors. We can teach them by not providing food for them, and by making sure they know there are certain area they’re not allowed. Can coyotes and people live more safely together in cities?

The coyote (丛林狼) , that clever animal of wide-open spaces, has come to the nation’s capital. In fact, coyotes have spread to every corner of the United States, changing their behaviors to fit new environments and causing researchers to deal with a troublesome new kind of creature：the city coyote.

The coyote originally lived in the middle of the continent. One of its most obvious characters is its smartness, which has made the animal a notorious (臭名昭著的) pest. Hunters trapped, shot and poisoned more than a million coyotes in the 1900s. It’s still one of America’s most-hunted animals. Yet the coyote has survived. How has the coyote shown this extraordinary ability? “I guess if you wanted to use one word, it’d be ‘plasticity’ , ” says Erie Gese, an expert at Utah State University. Coyotes can live alone, in pairs, or in large packs like wolves, hunt at night or during the day, occupy a small region or an area up to 40 square miles, and live on all sorts of food, from lizards (蜥蜴) and shoes, to ants and melons.

Unbelievably people helped coyotes increase when they killed most of the wolves in the United States. The spreading of coyotes into city areas, though, is recent. They travel at night, crossing sidewalks and bridges, running along roads and ducking into culverts (钻入洞) and underpasses. No one knows why coyotes are moving into cities, but experts explain that cleverer, more human-tolerant (不怕人的) coyotes are teaching urban survival skills to new generations.

Occasionally, coyotes might attack human beings. There have been about 160 attacks on people in recent years. Therefore, people have been consistently told not to feed coyotes or leave pet food unsecured. That, plus a large trapping program in the neighborhood, has cut down on the coyote population.
