摘要
Pesticides were blamed when familiar songbirds were suddenly stilled in the 1960s. The worst culprits were banned, but migratory songbirds continue to decline. The reasons, the author argues, are increased pressure from predators and parasites in North American nesting sites and deforestation of tropical wintering areas.
