Chile's Humboldt penguins under threat of extinction
just added by Paulina Abramovich
Humboldt penguinswhich nest only in parts of Chile and Peruover the years have become decimated by human encroachment, rat infestations and unforgiving weather currents carried by unusually warm El Nino ocean temperatures, naturalists said.
The Pajaro Nino islet, spread across a narrow channel of water from the popular resort area of Algarrobo, once drew about 2,000 of the birds during nesting season.
Today only about 500 of the birds come to this area some 120 kilometers (75 miles) west of Santiago.
