Long ago, the sky over California was full of condors (美洲秃鹰). Today, the sky is full of airplanes. People have taken over the condor's space. These big birds with giant wings are dying out.

　　Condors once flew along the Pacific Coast from Canada to Mexico. Then people moved into woods where the birds lived. By 1970, there were only about 50 condors left along the coast. Now there are less than 30. None of these birds may be left in 20 years.

　　Most people think the condors should be saved. People have different ideas for helping the birds. One group of people wants to study the birds and find out where they go. They also want to take the birds to zoos so that baby condors can be born there. A second group of people wants to leave the birds alone. Instead, they want to protect the wild places where the birds live.
