Salt Lake City is known for many things. It is named for the Great Salt Lake, which is the largest salt water lake in North America. The city held the 2002 Winter Olympic Games. Now, it is famous for helping to protect a family of peregrine falcons.

Young peregrine falcons begin learning how to fly when they are about five or six weeks old. It takes about a week for the parents to teach them. In natural areas, it is a bit safer for the young birds to take the risks that come with learning to fly. In cities, it can be more dangerous because they can hit the buildings or fly into traffic.

In Salt Lake City, volunteers (志愿者) put on bright orange vests (背心)to protect themselves as they keep an eye on the young birds. These volunteers actually put themselves in danger to save the birds. For example, if a young peregrine falcon accidentally flies into traffic, one volunteer stops traffic. Another tries to catch the bird and move it out of harm's way.

Bob Walters, one of the volunteers, joins a group of more than 20 people interested in the peregrine falcons. They give some basic training on what will need to be done once the young birds start flying. Jon Everts has been volunteering for several years. He says he keeps coming back because it's one of the world's fastest birds.

Many birdwatchers in the area heard about the nests and the young falcons. Some of them came out to help. Others just wanted to watch as the babies took their first flights. The volunteers are right to be worried about the young falcons. In the last few years, people counted 16 young peregrine falcons around downtown Salt Lake City. Only 11 of those birds continued to live. Of the 11 birds, six were helped by volunteers.

These numbers help the volunteers remember that the work they are doing really makes a difference. Some of them work 12-hour days to protect the peregrine falcons and their families. However, when the volunteers see a new generation (一代) of falcons that are ready to leave home, it makes all their work meaningful.
