Three themes of "A Minor Bird" by Robert Frost

The theme of this poem to me personally is to do with depression. The person perceives the bird singing as a nuisance and wishes for it to go away where he'll later come to regret the decision. Have clapped my hands at him from the door when it seemed as if i could bare no more. The person has finally gotten rid of the bird by clapping his hands because he had had enough of it. The fault must partly be in me the bird was not to blame for his key, this is the first sign of regret shown by the poet. The person would now ponder at first but later on he would come to realize that the fault was in him to silence nature, this reflects upon the last stanza " and of course there must be something wrong in wanting to silence any song".

This is of course just how i perceive the poem different mindsets could differ how you would put it as.
