She said Whooper was very happy, despite his pining for a helicopter, but as swans tend to mate for life finding him a partner would help keep him safe. 她表示这只雄天鹅非常开心。不过尽管他痴恋直升机,但由于天鹅是会与伴侣厮守终生的鸟类,为了他的安全着想还是得给他找个伴侣。
Whooper, who lives at a country club close to the island's airport, lost his partner two years ago. 这只天鹅在两年前丧偶,他所在的乡村俱乐部临近泽西岛的飞机场。
