North Quarter Farm in Riverhead L.I. NY has produced a BLACK Buffalo in 2009. The owner Edwin Tuccio, president of National Bison Foundation, does not know of any other farm that has produced one.
Since 2009 black calf's have been born almost every year. Last year 2017, three were born. Tuccio thinks one of his Bulls is carrying the Black gene.
