We get into the nuts and bolts of tracking the nightly movements of migratory birds with one of the original pioneers of nocturnal flight call monitoring.

工作：我们与夜间飞行呼叫监控的先驱之一一起深入了解跟踪候鸟夜间活动的具体细节。

We illuminate some of the threats birds face during migration and how scientists are combining weather radar and night call monitoring to aid migratory bird conservation efforts.

我们阐述了鸟类在迁徙过程中面临的一些威胁，以及科学家如何将天气雷达和夜间呼叫监测结合起来，以帮助候鸟保护工作。
