Like most birds, the cerulean warbler is a fussy sort. The tiny creature, just inches long, nests only in the tops of deciduous trees, those that lose their leaves in winter. With males a vivid sky blue, it's a "gorgeous bird," says ornithologist Jeffrey Wells. It's also in trouble. In three decades, its numbers have declined by about 80 percent. It is one of the fastest-declining forest birds in the United States. So how do we protect the warbler and other creatures in similar deline? Recent research by Wells and others has cast doubt on whether the current methods are working as well as they could.
