Storks[1] are faithful[2] animals. Year after year, the couples, which stayed together for life, always return to the same nest. Storks' nests are very big and made with anything the storks can find: branches, manure, rags even newspaper. These nests can weigh up to fifty kilos especially since the storks add to them every year. To support such constructions in the past, storks nested[3] in big trees or on rocky cliffs. But when they discovered human dwellings they immediately found that chimneys would be perfect for their nests. Especially because it's rare, human beings welcome them with open arms. And they've even converted the chimneys so the storks could be even more comfortable. And for centuries now storks have returned every year to the same nests.

鹳

　　鹳是忠心的动物，一对鸟夫妻终生相守在一起，年复一年，鸟夫妻总是回到同一个巢里。鹳的巢很大，它们用所能找到的东西来筑巢、树枝、粪土、报纸及碎布。这些巢可重达50公斤，特别是因为鹳每年都加些东西上去。过去鹳都把巢筑在大树上或者岩石悬崖上, 但当它们发现人们的住屋时，它们马上发现烟囱是它们筑巢的好地方。特别因为，虽然很少如此，人类张开双臂欢迎它们，并且移动烟囱让鹳可以住得更舒服些。几世纪以来，鹳总是每年回到同样的地方。
