I'm hoping that someone can help me here. I am trying to track down a poem that I taught to my year nine and ten students in the 1970s in Victoria, Australia. The poem was taken from a school poetry text used at the time, the name of which also eludes me. The poem is about a blackbird in a cage. The poet is enthralled by the beauty of its song. However, the next day when he goes to the cage, he finds the bird dead. I can't remember any more details than these, except to say that the poem is indescribably sad.
