As spring progresses, birds are returning to their summer habitats. Watch them as they build their nests and raise their young. Cameras mounted near nests capture images and live video of birds in their natural habitat. Current cams, as well as archived video reaching back to 2000, provide a close-up look at the lives of barn owls, bluebirds, wrens, seabirds, ducks, robins, swallows, and other bird species found in the United States.
