žThe Poem "The Laburnum Top" is a beautiful poem by Ted Hughes. In this poem, the poet has used the Laburnum tree and goldfinches as a symbol of life and its fluctuations. žHe describes the visiting of goldfinches on the Laburnum tree and how she has made a nest on it. When the goldfinches have chicks, it brings alive the tree as the chicks start to rustle and chirp. ž Hughes is trying to convey the message that life is a process of exchange and transformation. People are alive because they undergo exchange of energy. The goldfinches transform the tree and make it alive, without the goldfinches and the chicks the laburnum is just another tree.
