秋后,紫燕们为了躲避入冬后的寒流,是该回到大洋的彼岸去了。它们是从大洋彼岸来的,来到此岸产卵孵雏。如今雏燕已经褪尽了一层绒毛,令箭似的紫羽毛同母亲一样有了泛黑的光泽。但它们毕竟还嫩,有限的耐力还不能负担远征的沉重,妄想横越眼前的大洋是断不可能的事情。 After the fall, Ziyan went back to the other side of the ocean in order to avoid the cold current after entering the winter. They came from the other side of the ocean and came to lay eggs on this shore. Today, the young bird has already faded a layer of fluff, making the arrow-like purple feathers have the same pan-black luster as their mother. But after all, they are still tender. The limited endurance cannot afford the heavy burden of the expedition. It is impossible to imagine that crossing the ocean in front of them is impossible.
