a singing bird meaning in English

像一只歌唱的鸟儿

My heart is like a singing bird whose nest is in a watered shoot ; my heart is like an apple tree whose boughs are bent with thickset fruit ; my heart is like a rainbow shell that paddles in a halcyon sea ; my heart is gladder than all these because my love is coming to me
我的心像只鸣啼的小鸟在柔润的技条上筑着巢;我的心像棵苹果树被累累的硕果压弯了腰;我的心像个虹彩的贝壳在平静的海上轻轻荡漾;我的心比这些还更欢畅因为我的爱情已经来到。
