Many bird species migrate in order to survive. However, migration is a perilous journey and involves a wide range of threats. Only a small number of birds are actually threatened by natural events. Sad but true, human activities are the source for most dangers migrating birds are exposed to. And as diverse as people and their habits in different countries are, so are threats the birds face.
The loss of habitats due to pollution or exploitation caused by encroachment for settlement, agriculture, grazing etc. is the main threat migrating birds face, as They are dependent on finding suitable breeding and wintering grounds as well as stopover sites along their flyways where they can rest and feed. The loss of any of these sites used by the birds during their annual cycle could have a dramatic impact on the birds' chances of survival. Also, high-voltage power lines and wind turbines have a dramatic impact on birds, which are in danger of being killed by electrocution or collision. Poaching remains widely practised in countries where people are highly dependent on biodiversity for their livelihoods.

On a national level, the Audubon society has been conserving land and pushing for important legislation for over a century. The list of legislation created or assisted by the National Audubon Society is extensive, and includes the 1918 Migratory Bird Treaty Act, the 1964 Wilderness Act, the 1972 banning of DDT by the EPA, and the 1973 Endangered Species Act. Since it's inception the organization has preserved hundreds of thousands of acres of habitat across America, ensuring that many species of birds and other animals would have livable wilderness
