Wild little bird, who chose thee for a sign To put upon the cover of this book? Who heard thee singing in the distance dim, The vague, far greenness of the enshrouding wood, When the damp freshness of the morning earth Was full of pungent sweetness and thy song?
Who followed over moss and twisted roots, And pushed through the wet leaves of trailing vines Where slanting sunbeams gleamed uncertainly, While ever clearer came the dropping notes, Until, at last, two widening trunks disclosed Thee singing on a spray of branching beech, Hidden, then seen; and always that same song Of joyful sweetness, rapture incarnate, Filled the hushed, rustling stillness of the wood?
We do not know what bird thou art. Perhaps That fairy bird, fabled in island tale, Who never sings but once, and then his song Is of such fearful beauty that he dies From sheer exuberance of melody.
For this they took thee, little bird, for this They captured thee, tilting among the leaves, And stamped thee for a symbol on this book. For it contains a song surpassing thine, Richer, more sweet, more poignant. And the poet Who felt this burning beauty, and whose heart Was full of loveliest things, sang all he knew A little while, and then he died; too frail To bear this untamed, passionate burst of song.
