科学家们最近研究发现,候鸟能够一直不停地飞行,是因为得益于它们大量饱食以及成V字形队排列。瑞典隆德大学的研究人员从新陈代谢的角度考察了食物数量和效果的关系后发现,鸟类在体内存储了大量食物时能够更有效地飞行。在作长途飞行前,鸟类能够使自己的体重加倍,但却不会因此而飞不动,而是飞得更好、更远了。 Scientists have recently discovered that migratory birds can keep flying because they are heavily fed and arranged in a V-shaped team. Researchers at Lund University in Sweden looked at the relationship between food quantity and effects from a metabolic perspective and found that birds can fly more efficiently when they store large amounts of food in their bodies. Before long-distance flight, birds can double their weight, but they do not fly because they can fly better and farther.
