Whooping Crane 鸣鹤
The Whooping Crane is much larger than the common crane,which it otherwise much resembles except in color;its plumage,in its adult state,is pure white,the tips of the wings black.He spends the winter in the southern parts of North America,and in summer migrates far northwards.The crane feeds on roots,seeds,etc.,as well as on reptiles,worms,insects,and on some of the smaller quadrupeds.They journey in flocks from fifty to a hundred,and rise to an immense height in the air,uttering their loud harsh cries,and occasionally alighting to seek food in fields or marshes;and when they descend on a field they do sad havoc to the crops,several doing sentinel duty while the majority are feeding.In general it is a very peaceful bird,both in its own society and those of the forest.
和普通的鹤相比,鸣鹤要大得多,颜色也不一样,除此之外,它们看起来倒是很像。长大后的鸣鹤一身纯白,只有翅膀顶端是黑的。它们在北美南部过冬,夏天,则向北迁徙到很远的地方。鸣鹤以植物的根、种子等为食,也吃爬虫、蠕虫、昆虫和其他一些小的四足动物。它们成群结伴而行,每次五十到一百只不等。它们飞得很高,一边飞还一边沙哑地高声鸣叫。偶尔落在田野里或湿地里找食吃,这时就会给庄稼带来灭顶之灾。大部队找食吃的时候,还有几只得站岗放哨。总体来说,无论在自己的小圈子内,还是在整个大森林里,鸣鹤都算是一种比较温和的鸟。
