KIDNAPING THEIR YOUNG, THE AUTHOR TRICKED WARY TRUMPETER SWANS INTO TALKING FOR THE "MIKE" For five days the birds were patiently stalked without a close-up or a sound record of their voices. But ten minutes after thelittle cygnets were imprisoned inthe screen cylinder, the two old birds glided up close to the expedition's blind and began talking to their children. WhenDr. Allen released theyoung swans, there was a grand family reunion, and the microphone recorded the lisping calls of the cygnets as well as the hoarse trumpetings ofthe parents. Thought once tobealmost extinct, these largest of North American wild fowl are now increasing in numbers under protection. There are at least 75 in theYellowstone region, and more inBritish Columbia.
