迁徙

Recognising that pastoralism frequently needs to cross international borders, and that regional trade needs support, several international institutions are formalising cross-border pastoral mobility.

Keeping track of bird movements and numbers is greatly aided by flocks of amateur ornithologists who report their observations to bodies such as the British Trust for Ornithology, and amateur palaeontologists get in on the act when they uncover new fossils.

了解和掌握鸟类迁徙的情况和数量，离不开大批业余鸟类学者的巨大贡献，他们会将自己的观察记录报告给英国鸟类学基金会之类的组织。

They had wandered far and wide, and after many years of dreary peregrinations they had been given shelter in Egypt.

他们辗转迁徙，经过长时间的游隼后，终于在埃及找到了栖身之地，500多年间他们一直居住在埃及，直到这片国土被希克索斯人所侵略时，他们试图以对抗侵略者来发挥他们的力量，最终使得牧场得以保全。

Due to many reasons of multiple folk migration, transmigration and dynasty successions in history, different ethnic groups are mixed and gathered with others.

由于历史上多次的民族迁徙、移民以及朝代更迭等原因，中国各民族的分布形式成了又杂居又聚居、互相交错居住的状况。
