L. M. Veldhuis, et al. “How Swift s Control Th eir Glide Performance
with Morphing Wings.” Nature 446 (April 26, 2007): 1,082-1,085.
Th e researchers conducted wind tunnel experiments demonstrating
that by changing the shape of their wings, swift s can fl y up to 60 per-
cent farther and turn up to three times faster.
