New Poetry Wordsworth's Cuckoo is a symbol that encompasses many of the Romantic poets' concerns. This curious description of the bird's call refers of course to the double syllable of the song. Throughout the poem we see that duality. Wordsworth uses the physical bird as a doorway into symbolic worlds.
Clues are everywhere.
It transports the poet into the realm of imagination, sensibility stretched and on fire. And in that world the Cuckoo is a doorway into the past. One should not underestimate the significance for the Romantics of this special doorway into their childhood. The language of the final stanza is quite telling. For the poem, like the bird is supposed to auger something new.
