What are the ancient poems describing Zigui birds?

The fragrant spring is flat and green, and the child cries in the clear night. ("Sleeping at Qipanling" by Shen Quanqi of the Tang Dynasty)

I heard Zigui's cry again, and I was worried about the empty mountain at night. ("The Road to Shu is Difficult" by Li Bai of the Tang Dynasty)

When all the poplar flowers have fallen, Zigui cries, and he hears the dragon marking the road crossing the five streams.

The flowers are falling and the children are crowing, and the green window is full of dreams!

The mountains are green and the rivers are white, and the rain is like smoke amid the sound of the rules.

Zigui birds were heard in Shu, and azaleas were seen in Xuancheng. One cry, one ileum, one break, three springs and three months of memories of Sanba.

In the meantime, I heard something at dawn and dusk. The cuckoo sang and the blood ape screamed.

As the moon sets and the moon comes to rest, the apricot blossoms fill the mountains.

The butterfly dreamed of a home thousands of miles away, and the branches of the tree were updated three times a month.
