Emperor Penguins are More Willing to Relocate Than Previously Thought

Discovery of movement challenges long-standing theory that colonies return to the same area each year to nest A new study led by the University of Minnesota offers new insights on the long-term future of emperor penguins by showing that the penguins may be behaving in ways that allow them to adapt to their changing environment better than we expected. Researchers have long thought that emperor penguins were philopatric, which means they would return to the same location to nest each year. The new research study used satellite images to show that penguins may not be faithful to previous nesting locations. Researchers involved in the new study found six instances in just three years in which emperor penguins did not return to the same location to breed. They also report on one newly discovered colony on the Antarctic Peninsula that may represent the relocation of penguins. University of Minnesota College of...
