BBC News – Peru examines deaths of more than 500 pelicans
The government of Peru has warned people to stay off beaches along large stretches of its coastline as it investigates the mysterious deaths of hundreds of dolphins and seabirds.
More than 1,000 birds, mostly pelicans, have washed up dead along the northern Pacific coast in recent weeks, after many dolphins died in the same area.
The health ministry stopped short of closing beaches.
But it advised people to stay away until the health alert was lifted.
The area affected includes popular beaches near the capital, Lima.
