The article focuses on new Audubon reports which examined the link between birds and climate change. Greg Butcher, National Audubon Society's director of bird conservation and report coauthor, says their study shows climate change has affected the vast majority of birds in North America. Aside from climate, food supply also affects bird movement. Just like the national report Audubon California's study used Christmas Bird Count (CBC) data, but it also employed climate models to project how birds' ranges might change as temperatures increase. Other factors that the models did not consider, like nesting habitat and food availability, also determine a bird's resilience in a new area.
