Cerulean blues

Cerulean Blues describes the plight of the cerulean warbler, a tiny migratory songbird, and its struggle to survive in ever-shrinking bands of suitable habitat. This elusive creature, a favorite among bird watchers and the fastest-declining warbler species in the United States, has lost 3 percent of its total population each year since 1966. This precipitous decline means that today there are 80 percent fewer ceruleans than 40 years ago, and their numbers continue to drop due to threats including deforestation, global warming, and an ecologically devastating practice -- mountaintop removal coal mining -- that affects not only the cerulean warbler but all residents of the Appalachian mountains, including humans.
