These are birds with history, Summers says. "They are, you know, what you would have found in colonial barnyards."
And you'll find them today in recreations of those 17th and 18th-century barnyards, like the ones here at Claude Moore Colonial Farm outside Washington, where workers in period costumes are chopping wood for the fire. Summers started volunteering at the farm when she was just 11. It was here, she says, she grew to love and appreciate these uncommon birds.
"When I started learning more about their history and their place in the world now, I realized how rare they are and how important it is to preserve them."
Julie Long is a turkey researcher at the U.S. Department of Agriculture. She says today's commercial birds were bred for size, then crossed with white-feathered varieties to produce unblemished skin.
"And then those birds became very popular in about the 50s and just took over the market at that point."
And heritage breeds nearly disappeared. Today there are fewer than 10,000 Standard Bronze turkeys left, according to the American Livestock Breeds Conservancy.
Local livestock breeds are threatened in many parts of the world. One reason is efficiency is trumping diversity in order to meet the growing demand for animal protein.撒了一把玉米，瑞秋.萨默斯的火鸡赶紧跑了过来。瑞秋在距华盛顿一小时行程的克罗福特农场饲养了一小群被称作青铜火鸡的物种。
他们是有历史的禽畜。萨默斯说：“你知道，他们应该是你在殖民地仓院中能看到的禽类。”
今天，你将在重现了那些17和18世纪仓院的地方看到青铜火鸡，就像在华盛顿市郊克劳德穆尔殖民地农场看到的一样。在农场中，穿着具有时代特征服装的工人们正在伐木烧火。萨默斯只有11岁的时候就开始在农场义务服务。她说，她就是在这开始喜爱和欣赏这些不寻常禽畜的。
“当我开始更多地了解他们的历史和现在的生存地后，我意识到它们有多稀有，保护他们是多么的重要。”朱莉朗是美国农业部的一名火鸡研究员。她说，现如今赚钱类的禽畜之前被规模性饲养，然后与具有白色特征的品种杂交，进而得到完美无缺的皮毛。“大约在50年代，这些禽畜变得受欢迎并且就在那时占领的市场。”
传统物种几近消失。根据美国禽畜品种管理机构所说，现存的青铜火鸡数量不足一万只。
在世界上的很多地区，当地的禽畜品种都受到了威胁。一个原因是，为了迎合对动物蛋白质日益增长的需要，对于（饲养）效率的重视正在逐步超过物种多样性。
