I'm including part of the poem for you to check.
"No Nightingale did ever chaunt more welcome notes to weary bands
Of travellers in some shady haunt, Among Arabian sands:
a voice so thrilling ne'er was heard
In spring-time from the Cuckoo-bird ....."
1) The girl's song is compared first to the singing of the nightingale and then to that of the cuckoo-bird.
2) You have already checked this part. I just wanted to know if I should use the present or the past (?) when referring to the romantic poet Wordsworth.Thank you.
1)Wordsworth believed (?) poetry should deal with everyday situations or incidents and with ordinary people living in the countryside. He regarded (?) imagination as a special intuition which enabled the poet to see things the ordinary man was blind to.
1. Then your original sentence is correct.
2. When you write about the poet and what he thought and did, you can use the past tense. When you write about one of his works, you use the present tense.

Scroll down to where the site tells you how to write about poetry (about using slash marks / to indicate the end of one line and the beginning of another.
Then below that there is a discussion of verb tenses and when to use present or past.
