Weeks ago,Chicago became the first city in the US to join the"Lights Out Plan".People(38)Dthe lights in the city's tallest buildings,so that thousands of birds could get to their winter homes.Every year in autumn,some birds fly over Chicago on their way to the south,and(39)Athe next spring.Lights mean danger to birds.Birds find their way by looking at the stars in the sky.Lights in tall buildings are so bright that birds may mistake them as stars.This means they cannot find the(40)Bway to go home.
This time,about 300 types of birds are flying over Chicago to go back to the south to live through the cold winter.Many birds cannot live in the cold places,so they fly to(41)Eplaces.Another reason is that they want to have baby birds.Many birds like to have their baby birds in the same"house"they lived in (42)Fyear,so they fly back there.
