1.the chirps of birds
eg:There I would enjoy the peace and quiet, watch the water rush downstream and listen to the chirps of birds and the rustling of leaves in the trees.
在那里, 我可以享受平静与安宁,观看河流奔涌而下,倾听鸟儿啾啾鸣叫和树叶沙沙作响。

eg:Well you can sometimes hear birdsong in the city but it's the buildings that cause these natural sounds to be drowned out.
有时候你在城市听到鸟叫声,但是正是这些建筑淹没了这些自然的声音。
