Frost has presented nature in quite an unconventional manner. While in other nature poems we come across birds such as nightingales or sparrows, Frost has used a crow in this poem. A crow can be associated with something dark, black, and foreboding. That is why other poets usually mention singing nightingales or beautiful white doves in their poems. Also, the poet has written about a hemlock tree, which is a poisonous tree. He has not written about a more beautiful tree such as a maple,an oak tree or a pine tree because these trees symbolize beauty and happiness. Frost wanted to symbolize the feelings of sadness and regret, which is why he has used a hemlock tree.
The crow and the hemlock tree represent sorrow. The dust of snow that is shaken off the hemlock tree by the crow stands for joy that Frost experiences. He has, therefore, used an unconventional tree and bird in order to contrast them with joy in the form of snow.
