The Abaco Barb or Abaco Spanish Colonial Horse was a breed or population of feral horses on the island of Great Abaco, in the Bahamas. It became extinct in 2015, it was the only horse breed of the Bahamas. The origin of the Abaco horses is not known. It is possible that horses came ashore on Great Abaco from Spanish ships wrecked on its coasts, and also possible that horses were brought to the island by Loyalists who came there following the American Revolution. The most probable explanation is that they derived from horses used by Cuban forestry workers in the early nineteenth century.. For more information visit the Wikipedia page.
