许多人认为鸟巢就是鸟儿的家,每当风雨袭来,它们会躲进这个“避风港”,每当夜幕降临,它们会在这个“安乐窝”里睡觉。事实果真如此吗? 科学家发现,狂风暴雨时,许多鸟并不躲在窝里,还有许多鸟也不在巢中过夜。夜晚,野鸭和天鹅把脖子弯曲着,将头夹在翅膀间,漂浮在水面上入睡;鹤、鹳及鹭等长腿鸟类,更是站在地上睡觉。 Many people think that the bird’s nest is the home of the birds. When the storm hits, they will hide in this “safe haven”. When night falls, they will sleep in this “comfort nest”. Is it true? Scientists have discovered that many birds do not hide in their nests during the storm, and many birds do not stay in their nests. At night, wild ducks and swans bent their necks and caught their heads between their wings and floated on the water to fall asleep; long-legged birds such as cranes, pelicans, and herons stood on the ground to sleep.
