Fun facts

  • Its nasal horns, larger in males, are modified scales with no clear defensive function: they seem to play a part in dominance displays between males.
  • It is an important disperser of seeds in the island's dry forest: several plants germinate better after passing through its gut, and its decline affects the regeneration of that vegetation.
  • Feral pigs are its main threat: they dig up and eat whole clutches, and in several parts of Haiti no recent generation has survived.
