The Institute of Environment and Natural Resources said 530 penguins, numerous other sea birds, 5 dolphins and 3 giant sea turtles have been found in the coastal towns of Peruibe, Praia Grande and Itanhaem, with more likely on other nearby beaches. Sao Paulo University biologists and a wildlife research center are looking into the possible reasons for the animal deaths, the institute said. Praia Grande authorities have ruled out pollution, saying preliminary investigations point to starvation as the cause. The most likely scenario for the penguin deaths is exhaustion and hunger during their long migration from the waters off Argentina's southern Patagonia region, said Andrea Maranho, a veterinarian for the Sea Animal Rehabilitation Center in Praia Grande. -- Communicated by: HealthMap Alerts via ProMED-mail <promed(a)promedmail.org> [Migration is exhausting for birds, and without a good store of fat before the journey, they will not make it. What is unusual here is that there are other seabirds, dolphins and sea turtles involved, which makes me wonder if these animals all died at approximately the same time from a related cause. Perhaps something like red tide? Perhaps a small bloom? Maybe domoic acid? In the past, migrating penguins have died of starvation, avian influenza, and malaria. While some have suggested Newcastle disease, there are no confirmed reports of penguins dying of Newcastle disease. While there may be environmental reasons for the die-off, it has not been indicated in this article that infectious reasons have been ruled out. If necropsies have found empty stomachs in the birds, it would be nice to know what the fat stores of the birds are. Also, if it is starvation, is this the same cause for the dolphins and the sea turtles? Does this indicate over fishing of the same feeding area these animals need for survival? - Mod.TG] [see also: 2009 ---- Undiagnosed die-off, penguins - Chile (03) 20090405.1311 Undiagnosed die-off, penguins - Chile (02): clarification 20090403.1293 Undiagnosed die-off, penguins - Chile 20090331.122] ................................................sb/tg/msp/lm *##########################################################* ************************************************************ ProMED-mail makes every effort to verify the reports that are posted, but the accuracy and completeness of the information, and of any statements or opinions based thereon, are not guaranteed.
