The Magic of Migration

The Magic of Migration, written by Judy Brause.

《迁徙的魔力》，朱迪·布劳斯 著

Introduction Some animals wing their way across the skies for hundreds or thousands of miles. Others thunder across great plains. And still others make their way through strong ocean currents. All are searching for food, water, warmer climates, or a place to raise their young, and all are taking part in the magic journey of migration.

引言 有些动物振翅飞过数百数千英里的长空 另一些动物轰隆隆地横穿广袤的平原 还有一些动物在强劲的洋流中穿行 它们都在寻找食物、水源、更温暖的气候，或是养育幼崽的地方，全都参与了这场神奇的迁徙之旅

What is migration? Migration is the term scientists use to describe these animal journeys, and many different types of animals migrate. Birds, bats, whales, sea turtles, large grazers such as caribou and wildebeests, salmon, and even some kinds of insects move from one place to another to survive.

什么是迁徙？ 迁徙是科学家用来描述这类动物旅行的术语，许多不同种类的动物都会迁徙 鸟类、蝙蝠、鲸鱼、海龟，驯鹿、角马这类大型食草动物，鲑鱼，甚至部分昆虫，都会为了生存从一处迁往另一处

Some animals migrate at the same time every year and follow the same path. Others follow more irregular patterns because their movement depends on local conditions, such as the weather. There are also some animals that only migrate one way, such as masses of

有些动物每年都在固定时间迁徙，并且走同一条路线 另一些动物的迁徙模式更不固定，因为它们的移动取决于当地环境，比如天气 还有一些动物只会单向迁徙，比如成群的

Migration is one of the most dangerous journeys an animal can make. Migrating animals face many threats along the way, including hungry predators, strong winds, ocean currents, hunters, and fishermen. But migrating to find better living conditions is important for survival.

迁徙是动物所能经历的最危险的旅程之一 迁徙的动物一路上会遭遇许多威胁，包括饥饿的掠食者、狂风、洋流、猎人和渔夫 但迁徙寻找更优的生存环境对存活来说十分重要

The search for food and water. The most common reason why animals migrate is to find food and water. One of the most spectacular examples can be found in Africa. Every year, more than a million wildebeests, which are large grazing animals, migrate because of drought. When hot weather dries up grass and water supplies in one place, these fast -on -their -feet wildebeests travel in huge herds to find new sources of food and water. As these large mammals thunder across the Great Plains of Eastern Africa, hundreds of thousands of zebras and gazelles join them on their journey.

寻找食物与水源 动物迁徙最常见的原因就是寻找食物和水源 最壮观的例子之一就发生在非洲 每年，超过一百万只角马这种大型食草动物会因为干旱迁徙 当炎热天气把一处的青草和水源都晒干后，这些脚步轻快的角马汇成大群，前去寻找新的食物和水源 当这些大型哺乳动物轰隆隆横穿东非大草原时，数十万匹斑马和瞪羚也会加入它们的旅程
