The poem
Within a thick and spreading hawthorn bush That overhung a molehill large and round, I heard from morn to morn a merry thrush Sing hymns to sunrise, and I drank the sound With joy; and often, an intruding guest, I watched her secret toil from day to day— How true she warped the moss to form a nest, And modelled it within with wood and clay; And by and by, like heath-bells gilt with dew, There lay her shining eggs, as bright as flowers, Ink-spotted over shells of greeny blue; And there I witnessed, in the sunny hours, A brood of nature's minstrels chirp and fly, Glad as the sunshine and the laughing sky.

I'm writing the poem essay on "The Thrush's Nest" by John Clare. I need to write a title and start with an argument, Thesis of this poem.
