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?68.
