Attentive student of the songs of birds,
    No beakèd beast hath e'er more sweetly trill'd
A pair of notes or call'd in major thirds
    Or minor with musicality more skill'd.
Adaptive linguist, practic'd in the tongue  
    Of wingèd feather'd creatures, thou hast writ
Into "The Birdsong Songbook" songs unsung
    By birds which yet harmoniously fit.
And though the book began in higher throats
    Diversely tun'd by Nature's artful hand
Ere measur'd were the times and tones of notes,
    (Which often rest them now upon a stand),
Its finest lines (o'er which I now do rave)
Witness thy penmanship on every stave.
