Analysis of The Falcon

Why should my sleepy heart be taught
To whistle mocking-bird replies?
This is another bird you've caught,
Soft-feathered, with a falcon's eyes.

The bird Imagination,
That flies so far, that dies so soon;
Her wings are coloured like the sun,
Her breast is coloured like the moon.

Weave her a chain of silver twist,
And a little hood of scarlet wool,
And let her perch upon your wrist,
And tell her she is beautiful.
