For more than a hundred years, this sound has been missing from New Zealand's forests: (hihi call up and under) "It's like two stones being clicked together, or two marbles being clicked together. It's a very simple call." Oliver Metcalf, a conservation biologist at Manchester Metropolitan University, has studied the small bird that makes the noise—the hihi. By the 1880s, it was all but wiped out by rats and disease, which came along with colonists.
But the hihi did manage to survive on a predator-free barrier island called Te Hauturu-o-Toi. And now they're being reintroduced to mainland New Zealand. "And they're going through the process of trying to restore the ecosystems they had prior to colonial settlement there. So they're bringing back the birds one by one."
But the dense forests, and the birds' unusual behavior, makes them tough to monitor. "They're very inquisitive—they love people! So they'll come and see you. If they hear you coming, they'll come and see you. But that means you have a problem of knowing what they would have been doing when you're not there."

So instead, Metcalf and his collaborators from the Zoological Society of London used that distinctive call (hihi call) to their advantage—using an array of audio recorders to eavesdrop on 40 hihi birds reintroduced to the North Island's Rotokare Scenic Reserve. A month later, analysis of the calls revealed that the birds had abandoned some areas of the reserve, and settled into others... suggesting they'd begun to form territories, often close to water.
The details are in the journal Methods in Ecology and Evolution.
Metcalf says the concept could be used to monitor all sorts of animals. "So whether that's a reintroduction of a small mammal, or how existing birds species respond to a housing development nearby or something like that, this process could be used to understand how those populations respond to changes."
Assuming, that is, they make some noise.

这种声音已经在新西兰的森林中消失了100多年：（hihi鸟的声音）“这就像两块石头碰在一起，或是两块大理石撞在一起Cl2Uz%~zaPU。这是非常简单的声音Q,[0(-Jyl5HVg。”曼彻斯特城市大学的保护生物学家奥利弗·梅特卡夫研究了制造这种噪音的小鸟——hihi鸟cNl=vYM9C[[x&q1SM。到19世纪80年代，这些鸟几乎被随移民而来的老鼠和疾病彻底消灭ObzQh_3kTb2WS5J。

因此，梅特卡夫及其来自伦敦动物学会的合作者利用这一独特的声音（hihi鸟的声音）——用大量录音机来窃听重新引入新西兰北岛Rotokare风景保护区的40只hihi鸟;x4JGp_Z7ZUYdl4vfac。一个月后，对这些声音的分析显示，这些鸟已经放弃了保护区的一些区域，并在其他地方定居下来，这表明它们开始建立领地，通常是靠近水域的地区X6-uvwK(;8JQEq。

梅特卡夫表示，这个概念可以用来监测各种动物GivVgqGB-KvHOs。“因此，无论是重新引入小型哺乳动物，还是现有鸟类物种对附近住房开发做出何种反应，或诸如此类的事情，这一过程都可以用来了解这些种群如何应对变化(9F|6SU)9]=f+8M6l*%L。”
