“Keep a green tree in your heart and perhaps the singing bird will come.”

“Does the sweet morning rise,
Bride-like, from sleep,
When their first revelries
Bird and bee keep,
Singing out joyously
In the green tree?
Then, when my hopes are high,
Think I of thee.”

“My heart is like a singing bird
Whose nest is in a water'd shoot;
My heart is like an apple-tree
Whose boughs are bent with thick-set fruit.”

“The Admiral says that he never beheld so fair a thing: trees all along the river, beautiful and green, and different from ours, with flowers and fruits each according to their kind, many birds and little birds which sing very sweetly.”

“When the birds sing outside
And you see the trees
Changing into green
The sun invites one
To be out in the open air.
When the sky is so blue, then,
Oh! Then I wish for so much!.”

“From all the misty morning air, there comes a summer sound,
A murmur as of waters from skies, and trees, and ground. The birds they sing upon the wing, the pigeons bill and coo.”

“I walk where once the grass was green
And mourn the lark that sings no more
What bird could sing whose eyes have seen
Broken blossoms on the field of war?”

“In the desert a fountain is springing,
In the wide waste there still is a tree,
And a bird in the solitude singing,
Which speaks to my spirit of thee.”

“I sit in my tree
I sing like the birds
My beak is my pen
My songs are my poems.”

“When the bird of the heart begins to sing, too often will reason stop up her ears.”
