A dying pelican crawls away from the surf to die on the beach of Paita, in Tumbes, near Peru's border with Ecuador, on May 2. At first, Peruvian authorities said a virus was wiping out seabirds, but now experts say they are starving to death. A wave of warmer waters could be steering Peruvian anchovetas, which seabirds feed off, to cooler climates.

Seagulls and pelicans follow the wake of a fishing boat off Concepcion, Chile. Chilean officials have reported massive die-offs of seabirds on Chile's beaches. Scientists say the birds are being killed after becoming caught in fishing nets as they gorged on an unexpected windfall of fish seeking cooler waters.

A dead dolphin lying on a beach on the northern coast of Peru, close to Chiclayo, on March 27. Peruvian environment officials have said massive die-offs of dolphins and seabirds on their shores are linked by a virus. But independent scientists say the dolphins show signs of death from swimming too quickly up to the surface — much like the bends suffered by scuba divers — in a panic possibly caused by seismic testing in oil exploration.
