Collectively, the Standard and Broad Breasted varieties are simply called the Bronze turkey.

Later, beginning in the late 19th and early 20th centuries, some Bronze turkeys were selected for larger size.

Both have a brown color which is highlighted by shades of copper and blue-green, and the plumage overall is very similar to that of the wild turkey.

Due to their size, they have lost the ability to mate naturally, and Broad Breasted Bronzes in existence today are maintained entirely by artificial insemination.

Having retained the ability to reproduce naturally (among other traits), the Standard Bronze is considered to be a variety of heritage turkey.
