The Narragansett Turkey is a breed of Meleagris gallopavo which descends from a cross between the Eastern Wild Turkey (Meleagris gallopavo silvestris) and the domestic turkey brought to Colonial America by English and other European colonists beginning in the 17th century. According to the American Livestock Breeds Conservancy, the Narragansett Turkey is a "historic variety, unique to North America" and is named for Narragansett Bay
This is what I found
Not sure if it's the same as yours!
Unfortunately, I couldn't get any closer, and the zoom function made everything blurry...
I was taking the pictures from across the canal, and after reviewing my pictures, I don't see the really white one that first caught my attention. I believe s/he had already disappeared down the opposite bank by the time I got my camera out.
Coming down the road, I originally thought they might be turkey vultures, but when I got out of the car, I started talking to them to get their attention, and was greeted with a melodious and rousing concert of "gobble, gobble, gobble, gobble!" Definitely not vultures.
