I have a bird in spring

I have a Bird in spring
Which for myself doth sing -
The spring decoys.
And as the summer nears -
And as the Rose appears,
Robin is gone.

Yet do I not repine
Knowing that Bird of mine
Though flown -
Learneth beyond the sea
Melody new for me
And will return.

Fast in a safer hand
Held in a truer Land
Are mine -
And though they now depart,
Tell I my doubting heart
They're thine.

In a serener Bright,
In a more golden light
I see
Each little doubt and fear,
Each little discord here
Removed.

Then will I not repine,
Knowing that Bird of mine
Though flown
Shall in a distant tree
Bright melody for me
Return.
