"And from the bottom of the cliff I couldn't see what was happening in that nest.

点击显示原文

隐藏原文=

I couldn't even see whether the bird was home or not."

That's right - a drone.

点击显示原文

隐藏原文=

Gremillet says scientists and citizens alike are increasingly using drones to approach birds--either for fun or legitimate research.

点击显示原文

隐藏原文=

The study is in the journal Biology Letters.

点击显示原文

隐藏原文=

All these hi-tech tools could be a boon to wildlife ecologists.

点击显示原文

隐藏原文=

"But at the same time you always have to assess the impact of the technology you're using on animal welfare."

点击显示原文

隐藏原文=

And maybe drone welfare too.

点击显示原文

隐藏原文=

Search YouTube and you'll find that birds of prey, like some privacy advocates, perceive drones as a threat, and make the technology crash, literally.
