In the past ten days, around 2,000 penguins have been found dead along eastern Uruguay’s coast, baffling scientists.
Beachgoers in eastern Uruguay have been greeted by the alarming sight of dead birds, and no one knows the reason behind the mass deaths.
According to Carmen Leizagoyen, the head of the environment ministry’s department of fauna, the Magellanic penguins were mostly juveniles who died in the Atlantic Ocean and were carried by currents to the country’s shores.
‘This is mortality in the water. Ninety per cent are young specimens that arrive without fat reserves and with empty stomachs,’ she said.
She added that all samples from the penguins had tested negative for bird flu.
Magellanic penguins are a common species in South America and are known to migrate north in the winter in search of warmer waters and food.
‘It is normal for some percentage to die, but not these numbers,’ said Ms Leizagoyen, recalling that a similar die-off occurred last year in Brazil, for undetermined reasons.
Hector Caymaris, director of the Laguna de Rocha protected area, told AFP that he counted more than 500 dead penguins along six miles of Atlantic coast.
It is possible that the penguins were on their way to their breeding grounds in Argentina when they encountered harsh weather conditions or a lack of food.
Environmental advocates have attributed the deaths to overfishing and illegal fishing.
‘From the 1990s and 2000s we began to see animals with a lack of food. The resource is overexploited,’ Richard Tesore of the NGO SOS Marine Wildlife Rescue told AFP.
He added that a subtropical cyclone in the Atlantic, which hit southeastern Brazil in mid-July, probably caused the weakest animals to die from the inclement weather.
In addition to penguins, Tesore said he has recently found dead petrels, albatrosses, seagulls, sea turtles and sea lions on the beaches of Maldonado, another coastal city in southeastern Uruguay.
