The poem uses alliteration in lines 3 and 5 to create a sense of serenity in the landscape being described. The ending rhyme seems to add stress to the feelings presented. The main rhyme scheme is abaabcc. The rhyme scheme in this poem helps with the meter. The meter of the poem is an iambic pentameter which, when in rhythm with the words chosen so skillfully by the speaker, increases the urgency of the bird that is trying to escape from its cage. The use of punctuation in the last sentence of each stanza gives the feeling that the speaker is shouting it to emphasize how he feels about the bird. The grammar of the poem is in the present tense, making it as if the reader can see the bird, in its struggle, right before their eyes. This pulls some strings on the reader and makes them feel guilty for watching the bird and not doing anything to help it
