Charles Don Coppedge, age 13, Dallas, Texas, for his question:

How did the whooping crane yet its name?

The whooping crane is named for his booming, trumpeting voice. He does his best vocalizing when in flight and the echoes from his call can be heard over the lonely marshland after he has passed out of sight.

This rare, rangy fellow is the tallest of all American birds. He stands over four feet on long spindly legs. His windpipe, the organ he uses to make his whooping calls, is five feet long. It is a pipe reaching down his long neck to the breastbone. There it coils around like a musical horn which, of course, it is.
