Crow
its black feathers

shining with light

tumbles over
its broken wing

rights itself
again

as if it were Laurence Oliver
being Richard the Third

“Now, is the winter
of our discontent..! ”

Crying for its kingdom
of the skies

the failing light
hiding it in night

its curses
still visible

in the darkness.
