  Overton probably is trying to refer to European Starlings.

  Wrong.  There ARE grackles in Pennsylvania.  There are 3 species of grackles 
  in the USA.  The one known as "Common Grackle" occurs through most of the
  US and Canada, except for the cordillera and the west coast.  Then, there 
  are 2 much large grackles, that were split from each other in 1973.  The
  "Great-tailed Grackle" is common in Mexico and Texas, and is spreading north,
  east, and west.  The "Boat-tailed Grackle" is more or less restricted to
  salt marshes on the Gulf and Atlantic Coasts.  They all are native to North
  America.

  Those are the Great-tailed Grackles.
