Nearly two thousand dead penguins were found on the eastern coasts of Uruguay in ten days, the cause of this carnage remains unexplained. These Magellanic penguins, most of them young, died in the Atlantic Ocean before being brought back by the currents to the coasts of the departments of Canelones, Maldonado and Rocha (South and Southeast), explained Carmen Leizagoyen, in charge of wildlife issues at the Uruguayan Ministry of the Environment.
According to her, “90% are young specimens that arrive with no fat reserves and with an empty stomach.” The tests carried out to determine the presence of the avian flu are negative, she added. This species of penguin, which nests in southern Argentina, migrates north in search of warmer waters during the southern winter, and can go up to the coasts of the Brazilian state of Espirito Santo (Southeast).
“It’s normal for a certain percentage to die, but not as many,” said Ms. Leizagoyen, recalling that a similar carnage took place last year in Brazil, again for an unknown cause.
Hector Caymaris, the director of the protected Rocha lagoon, assured AFP that he had counted more than 500 dead penguins on 10 kilometers of beach. Conservationists blame Magellanic penguin mortality on overfishing and illegal fishing. “From the 1990s and 2000s, we started to see animals that lacked food,” said Richard Tesore, of the NGO SOS Sauvetage de la faune marine, pointing to “overexploitation” of marine resources.
According to him, the cyclone that appeared in the Atlantic, which hit southeastern Brazil in mid-July, had probably led to the death of the most weakened individuals, due to bad weather conditions. In addition to penguins, Tesore says he has found dead petrels, albatrosses, seagulls, sea turtles and sea lions on the beaches of Maldonado, east of the Uruguayan capital Montevideo.
