BirdLife is the global authority on the status of birds.
More than 40% of migratory species are declining,
and nearly 200 are now classified as globally threatened.
Migratory birds are some of the most inspiring impressive groups of birds, not only because of the spectacular views they offer as they move across the sky, but also because of the incredible distances they cover during their voyages.
Migratory birds mark the seasons as they leave their breeding areas before food gets scarce only to land on another continent to build a new life. When we enjoy the presence and behavior of these migratory birds we hope and even assume that they will return each year. Unfortunately many migratory species and especially the long-distance migrants do not return.
