Antillean Grackle ... after doing a Google Search this is what I learned...
The Greater Antillean Grackle known locally as the "Kling, Kling" bird lives up to his name when he starts making his "kling, kling" call. They love handouts and scraps of food and are not very shy especially when they are looking for a snack.
Jamaica has eight (8) different species of birds that are black in "colour", most of which are commonly called black birds by the layperson. These are the Greater Antillean Grackle (or Kling-Kling), Smooth-billed Ani (or Savanna Blackbird or Ani), Jamaican Crow (or Jamicrow), Greater Antillean Bullfinch (or Black Sparrow), the Jamaican Becard (or Judy or Rickatee), the Turkey Vulture (or John Crow), the Shiny Cowbird and finally the Jamaican Blackbird (or Wildpine Sargeant). Only the latter of is endangered and is restricted to increasingly disappearing mature rain forest of Jamaica’s interior mountains which now covers less than 6% of the island. The Jamaican Blackbird is the only species in a Jamaican endemic genus of bird species, with the result that it is not closely related to any other Jamaican bird or indeed to any other species of bird world-wide. How it got here and where its closes relatives are to be found are totally unknown to science. It is possibly our islands most endangered bird species and is in urgent need of scientific study.
