Biologists estimate that as many as 2 million lesser prairie chickens – a kind of bird living on stretching grasslands – once lent red to the often grey landscape of the midwestern and southwestern United States.
生物学家估计，曾经多达200万只的小 prairie 鸡——一种栖息在广阔草原上的鸟类——使美国中西部和西南部地区常常灰暗的景观增添了红色。
The crash was a major reason the u.s. Fish and Wildlife Service (USFWS) decided to formally list the bird as threatened.
这一数量锐减是美国鱼类和野生动物管理局（USFWS）决定正式将该鸟类列为‘受威胁物种’的主要原因之一。
They had pushed the agency to designate the bird as “endangered,” a status that gives federal officials greater regulatory power to crack down on threats.
他们曾敦促该机构将该鸟类列为‘濒危物种’，这一地位赋予联邦官员更大的监管权力，以打击威胁。
Under the plan, for example, the agency said it would not prosecute landowners or businesses that unintentionally kill, harm, or disturb the bird, as long as they had signed a range-wide management plan to restore prairie chicken habitat.
例如，根据该计划，该机构表示，只要土地所有者或企业签署了覆盖整个栖息地范围的管理计划以恢复草原鸡的栖息地，就不会起诉那些无意中杀死、伤害或干扰该鸟类的人或企业。
The federal government is giving responsibility for managing the bird to the same industries that are pushing it to extinction,” says biologist Jay Lininger.
生物学家杰伊·林杰说：‘联邦政府将管理这种鸟类的责任交给了那些正在将其推向灭绝的行业。’
