News release: “The United States WatchList, a joint project between American Bird Conservancy and the National Audubon Society, reflects a comprehensive analysis of all the bird species in the United States. It reveals those in greatest need of immediate conservation attention to survive a convergence of environmental challenges, including habitat loss, invasive species, and global warming. The list builds on the species assessments conducted for many years by Partners in Flight (PIF) on landbirds, using those same PIF standards, but expanded to cover species of all taxa. The list is based on the latest available research and assessments from the bird conservation community, along with data from the Christmas Bird Count and Breeding Bird Survey.”
