內容簡(jiǎn)介:Imagine it has been nearly two hundred years since hunters killed the last of the trumpeter swans living in the eastern part of North America. Now that the birds are protected by law, scientists hope to return the birds to their former range in the East. However, trumpeter swans must learn their migration routes from their parents—so scientists are taking on the role of parent swans in the Trumpeter Swan Migration Project, teaching cygnets to follow ultralight aircraft in an effort to reintroduce a migrating population to the Atlantic coast.
作者簡(jiǎn)介:Elinor Osborn learned of the Trumpeter Swan Migration Project when the biologist/pilot for the project presented a slide show at a local bird club meeting. The work sounded so exciting, she rolled out of bed at 4:30 a.m. a few days later to see the swans-in-training for herself. A professional photographer and writer, Elinor Osborn lives in Penfield, New York.
