LIMA, Peru -- A lack of anchovies and other small fish triggered by unseasonably warm waters has left thousands of seabirds starving to death along Peru's Pacific coast, experts say.

This month, the corpses of 5,000 birds, principally pelicans and boobies, have been discovered on beaches up and down the country, according to official government reports.

It is the second mass die-off this year in Peruvian waters, after hundreds of dolphin carcasses also mysteriously washed up on beaches in the northern regions of Piura, Lambayeque and Tumbes.

Initially, it was thought the bird and dolphin deaths might be related, and caused by a common virus, sparking mild panic and prompting many to avoid the beach during the last days of Peru's coastal summer.

That was ruled out after government scientists confirmed the appearance of a Kelvin wave, carrying warm water from Australia to surface in the western Pacific.

The wave has forced many fish species -- including the Peruvian anchoveta, a type of anchovy -- to migrate to colder seas further south, leaving Peru's seabirds with little food.

Ironically, it may have triggered a second mass die-off in Chile. More than 2,000 seabirds have died between Chile's Cartagena and Santo Domingo beaches after becoming caught in fishing nets as they gorged on the unexpected windfall.

The Kelvin wave may be a precursor of the periodic El Niño effect, bringing unusually damp, warm weather, including flooding, to Chile, Peru and Ecuador.
