A Bird Came Down

Assalamualaikum,

It all started when I saw something about Emily Dickinson. So, this is one of her poems:

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, splashless, as they swim. 

PS: I try to learn the implicit meaning behind the poem.....
