                              Special Bridges Help Animals Cross the Road

                                                            - Reported by Sheila Carrick

     Why did the chicken cross the road? To get to the other side.

     Most people know this joke. But recently, some people have been much more worried

about how the grizzly bear(灰熊) and mountain lion can cross the road.

     "Millions of animals die each year on US roads," the Federal Highway Administration

reports. In fact,only about 80 ocelots, an endangered wild cat, exist in the US today. The

main reason? Road kill.

     "Ecopassages (生态通道)" may help animals cross the road without being hit by cars.

They are paths both over and under roads. "These ecopassages can be extremely useful, so

that wildlife can avoid road accidents," said Jodi Hilty of the Wildlife Protection Society.

     But do animals actually use the ecopassages? The answer is yes. Paul Beier of Northern

Arizona University found foot marks left by mountain lions on an ecopassage that went under

a highway. This showed that the lions used the passage.

     Builders of ecopassages try to make them look like a natural part of an area by planting

trees on and around them. Animals seem to be catching on. Animals as different as

salamanders(火蜥蜴) and grizzly bears are using the bridges and underpasses.

     The next time you visit a park or drive through an area with a lot of wildlife, look around.

You might see an animal overpass!
