Meaning
The turkey vulture — the bald-headed black scavenger bird seen circling over the Jamaican countryside. Because it feeds on the dead, 'john-crow' is also a heavy insult for a low, contemptible, or vulture-like person who preys on others. It appears in countless proverbs ('john-crow tink him pickney white') and place names (the John Crow Mountains).
