During the summer of 2017 I headed out to a remote mountain ridge in Peru's Madre de Dios with a team of top-notch avian ecologists. We were to follow in the footsteps of a historic ornithology survey conducted over 30 years prior to see what had changed. Here is some news coverage from what we found.
In our article, published November 2018 in PNAS, we describe how birds from southeastern Peru have responded to climate change over the past three decades by comparing mist-netting and observational records from historic and modern ornithological expeditions. We found that the majority of birds have shifted their distributions upslope, and that some species once found only at the mountaintop have now disappeared. Read more about it through press releases from the BBC, Cornell Lab of Ornithology, and National Post.
