DDT was banned in nineteen seventy-two. Wildlife experts now bring baby peregrines from the Chesapeake Bay area. Then they place the birds in rocky areas high above the Potomac River near Harpers Ferry. The baby birds wear a device that sends signals telling where there are. The devices let wildlife experts follow the birds' movements. They hope that before too long, many peregrines again will fly in these skies.

现在野生动物专家从切萨皮克海湾地区引进隼雏，然后将这些隼雏放到位于哈珀斯渡口附近的波托马哥河上游的岩石区，专家们在这些隼雏身上安放了一种能够传送信号的装置，这种装置能够告诉专家这些隼雏在什么地方，这种装置让野生动物专家跟踪这些鸟的活动，他们希望不久以后能有许多游隼再次飞向这片蓝天。
