In the Garden
by Emily Dickinson
A bird came down the walk: 
He did not know I saw; 
He bit an angle-worm in halves 
And ate the fellow, raw.
And then he drank a dew 
From a convenient grass, 
And then hopped sidewise to the wall 
To let a beetle pass.
He glanced with rapid eyes
That hurried all abroad,--
They looked like frightened beads, I thought;
He stirred his velvet head
Like one in danger; cautious,
I offered him a crumb,
And he unrolled his feathers
And rowed him softer home
Than oars divide the ocean, 
Too silver for a seam, 
Or butterflies, off banks of noon, 
Leap, plashless, as they swim.
