Birds of prey spiralling to a kill
...flight might increase the birds' aerodynamic drag, slowing them down. To test this idea, Tucker placed life-sized models of peregrine falcons and red-tailed hawks in a wind tunnel. Sure enough, force sensors showed that, at a wind speed of 42 kilometres per hour, the drag on birds whose heads were turned 40...Chance discovery of 'immortal skin' holds medical promise
