What does it mean that songbirds move trees to swallow tall buildings?

It means that the oriole moved to a tree and the swallow moved into a high-rise building as his home, which means climbing to the top, rising or moving.

Source: from the pre-Qin anonymous "Logging": "Logging, birdsong. Transfer from the valley to the tree. Let it sing and ask for its friendly voice. I like birds, but I still want friends. You're Iraqi. You don't want friends? When God listens, it will be peaceful in the end. "

Knock-knock logging, birds sing harmoniously. Birds come from deep valleys and fly to the top of high trees. Why do birds sing? Just ask for a bosom friend. Look at the birds carefully, or want friends and blind dates. Besides, we people don't know how to cherish friendship. God in heaven, please listen and give me peace, joy and peace.
