The Smithsonian Migratory Bird Center is dedicated to understanding, conserving and championing the grand phenomenon of bird migration. Founded in 1991, and located at the Smithsonian's National Zoo in Washington, D.C., SMBC scientists seek to clarify why migratory bird populations are declining before the situation becomes desperate. Smithsonian Migratory Bird Center programs help raise awareness about migratory birds and the need to protect diverse habitats across the Western Hemisphere.

Since 1970, bird populations in the U.S. and Canada have declined by 29%, or almost 3 billion birds, signaling a widespread ecological crisis. The results show tremendous losses across diverse groups of birds and habitats — from iconic songsters such as meadowlarks to long-distance migrants such as swallows and backyard birds including sparrows.
