2. Write a brief essay either analyzing the ecological implication of the following poem in terms of noninterference, the law of the jungle, and the beauty of wildlife or explaining the theme of the poem from the point of view of the poet whom the scene has fascinated. 30% 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 around - 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.
