In this undated photo made available by journal Nature on January 15, 2014, a northern bald ibis (Geronticus eremita) flies in Tuscany, Italy. A new study released Wednesday, January 15, 2014 says the birds choreograph the flapping of their wings, getting a boost from an updraft of air in the wake of the flapping wings by flying behind the first bird and off to the side. When a flock of birds take advantage of these aerodynamics, they form a V. (Photo by Markus Unsöld/AP Photo)

“On the Li River near Xingping in China, Cormorant fishermen work the waterways before dawn amidst the spectacular limestone towers of the Karst landscape. The birds are trained to fetch fish from the inky depths but not swallow them. The fisherman accepts the fish from the birds who dive back for more. Here, still before dawn, the fisherman and his birds head for home”. (Photo and caption by Neville Jones/2014 Sony World Photography Awards)
