让每只鸟都计数(Make every bird count)

在接下来的四天里,来自世界各地的鸟类观察员将参加一项特别的年度活动:家禽的大量统计。在重新计票期间,鼓励鸟类爱好者识别在其区域看到或听到的有羽毛的朋友,并报告他们的发现。这些数据通过提供有关种群和栖息地如何随时间变化的信息,帮助科学家了解和保护鸟类。

In the next four days, bird observers from around the world will participate in a special annual event: a large-scale census of poultry. During the recount period, encourage bird enthusiasts to identify friends with feathers seen or heard in their area and report their findings. These data help scientists understand and protect birds by providing information about how populations and habitats change over time.
