Hummingbirds captured on high-speed video surprised University of Connecticut scientists with the way they drink; a bird dips its tongue in nectar, widens the forked tip and unfurls a fringe of hairlike structures.

The study refutes the long-held assumption that hummingbirds rely on capillary action to draw nectar up through grooves in their tongues.
