The Smithsonian Migratory Bird Center is dedicated to understanding, conserving and championing the grand phenomenon of bird migration. Founded in 1991, we are located at the Smithsonian's National Zoological Park in Washington, D.C. → Join our Center


One hundred years after the extinction of the passenger pigeon, the top bird-science and conservation groups in the nation have come together to publish The State of the Birds 2014—the most comprehensive review of long-term trend data for U.S. birds ever conducted.

The results are unsettling. The report indicates bird populations are declining across several key habitats, and because birds are important indicators of environmental health, these declines signal larger landscape changes that are affecting entire ecosystems.

However, the report also highlights where strategic investments in habitat conservation and science are resulting in recoveries and growing populations.

The report's authors, who represent 23 U.S. government agencies and nongovernment organizations, have also created a State of the Birds Watch List. The hundreds of species on the list are currently endangered or at risk of becoming endangered without significant conservation.
