Endangered Species Bulletin
Wildlife, it is said, knows no borders, and this is especially true for migratory birds. Many species travel great distances each year and face a variety of threats along the way. Some, like the whooping crane or Aleutian Canada goose, declined to the point that Endangered Species Act protection was necessary to prevent their extinction. After a great deal of hard work, these and other birds are on the road to recovery. But a more effective means of bird conservation is to prevent problems by maintaining healthy populations of associated species in secure habitats. The Fish and Wildlife Service, along with its many partners at the Federal, international, and local levels, is increasingly taking such an ecosystem approach.
