Why are migratory birds endangered?
MIGRATORY birds are becoming vulnerable to shifts in seasons. Climate change is modifying the time of seasons. Early arrival of spring at breeding sites is making it harder for the migratory birds to attract mates or find food. Scientists warn this ecological mismatch can reduce bird populations.
How many migratory birds are endangered?
Currently, the U.S. Fish and Wildlife Service notes that some 836 species of birds are protected under the MBTA, of which 78 species are listed as endangered and 14 species are listed as threatened under the Endangered Species Act (ESA).

The Decline of Eastern Songbirds. Since the end of World War II there has been a decline in forest songbird populations over much of the eastern United States.

Why are songbirds disappearing in North America?
Nearly 3 billion birds have disappeared across North America since 1970 — a 29% decline. Two-thirds of the continent’s bird species are at risk of extinction due to climate change. According to a new study, seabird populations in Alaska experienced unprecedented die-offs following a marine heatwave five years ago.
