Audubon California's own Bill Monahan has co-authored a fascinating new study on how birds in the Sierra Nevada are moving in response to climate change. The findings, published in the journal Proceedings of the National Academy of Sciences, reveal that 48 out of 53 bird species studied in California's Sierra Nevada mountains have adjusted to climate change over the last century by moving to sites with the temperature and precipitation conditions they favored.
"In order to conserve biodiversity in the face of future climate change, we need to know how a species actually responds to a warming climate," said study lead author Morgan Tingley, a Ph.D. student in the Department of Environmental Science, Policy & Management and at the Museum of Vertebrate Zoology at UC Berkeley. "Comparing past and present ranges of species that experienced climate change is one of the best ways to gain this knowledge. Understanding how species will respond to climate change allows us to take steps now to restore key habitats and create movement corridors that will help them respond to the changes we have coming."
