A new report issued today by the National Audubon Society finds that nearly 60 percent of the 305 species found in North America are shifting their wintering ranges northward by an average of 35 miles. Audubon scientists analyzed 40 years of citizen-science Christmas Bird Count data and found evidence that global warming is having a serious impact on natural systems. Northward wintering movement was detected among species of every type, including more than 70 percent of highly adaptable forest and feeder birds.

You can access the report here, as well as a Florida fact sheet, which provides an overview of some of the state's bird species, such as the Eastern Bluebird, which are showing signs.

These 305 bird species are the canaries in the coalmine for climate change, sending us a powerful signal that we must 1.) act now to curb the impacts of climate change by reducing global warming pollution and implementing energy efficiency and clean, renewable energy strategies; and 2.) help wildlife and ecosystems adapt to unavoidable habitat changes, even as we work to curb climate change itself.
