Answer:
Hopkins vividly conveys thoughts and feelings about the bird by showing how it feels prisoner and comparing it to the human being.
Explanation:
In this poem we can see how a skylark bird is imprisoned. That bird barely remembers what it was like to fly freely and both the bird and the soul and spirit of the human being "droop deadly in their cells".
Still they both have good times where they sometimes sing the sweetest spells.
According to the poet, the soul of each person seeks to fly freely, that is, to leave the cage that is the body and rise high towards the sky.
What is treated in this poem is the resurrection of the spirit, comparing it to a caged bird, where both seek the same.
