SYPNOPSIS
Many North American birds are in serious decline. But scientists aren't sure what's wrong, because birds are hard to count. The problem is partly that birds often migrate long distances between wintering sites and summer breeding grounds. Usually, they fly unobserved at night, and in many cases scientists don't know what route they take. However, a new technique promises to solve this problem.
