sonnet for the bird with the hollow song

i care no more for your enthralling song
your recitals i refuse to attend
those once-beloved lyrics now all but gone
with that performance, i cannot pretend

i am left more cautious since i have heard
your siren sound tempting my ships to harm
how you caroled us with your cloying words
and burned us with the bitters of your charm

now you've flown to feed upon new goodness
to trill your story for another soul
with fresh audience, no need to confess
to the deceit that exacted this toll

you flew alone by force of your own wing
from a cause you invented, did you sing
