Here is a piece of news for bird lovers. Scientists have painted a long road, red, yellow and white. They help to discourage the sea birds from wandering onto the highway. The area is home to large crowds of birds that come to stay for the season. Young birds are often attracted to the warm roads’ surface and get killed by the traffic. Biology student, Hannah tells the broadcaster. The youngster’s feathers are brown in color. The dark-colored road surface makes the youngster hard to be noticed. As the number of tourists has grown, so has the amount of traffic on the roads. Biologist Christen says the plan is to see how the birds respond to the multi-colored road this summer, and if it works, the idea could spread to other parts of the country.
