Pioneering Report Documents Plight of North American Birds

May 26, 2010

Nearly 150 species of North American birds are in significant trouble, according to a report released May 11, 2010, by a consortium of US, Canadian, and Mexican government agencies, NGOs, universities, and individuals. Of these species, 42 have plummeted by 50% or more in the past four decades.

All told, nearly a third of the 882 native landbird species that the three countries share are very dependent on lands in at least two of the countries. The authors say that the report is "the first comprehensive conservation assessment of bird species in North America."

One way to zoom in on this information is to see how the states, provinces, or territories you cover relate to migratory pathways that span the countries. A summary map for each state or province is available at:
