Emperor Penguins may not Return to Same Location to Breed Each Year – Maine News

It was considered that emperor penguins were philopatric, meaning they would return to the same location to nest every year. But as per a new research, such might not be the case as they might not return to the same location each year.

Researchers have come across six instances in three years in which emperor penguins did not return to the same location to nest. During the time of research, researchers have also come across new colony on the Antarctic
Peninsula representing the relocation of penguins.

Lead researcher Michelle LaRue from University of Minnesota College of Science and Engineering was of the view that the penguins might be behaving in this matter so that they can adapt as per their changing environments.

“Their research showing that colonies seem to appear and disappear throughout the years challenges behaviors we thought we understood about emperor penguins”, said LaRue.

LaRue stated that if they believe in the previous assumption then the new colonies that they have seen through satellites would not have any meaning. As per them, emperor penguins move among colonies.

Researchers have been studying the Pointe GĂ©ologie colony of emperor penguins for over 60 years. Lately, researchers became increasingly concerned about retreating sea ice. But in 1970s, it was noticed that the population declined by half. It was considered to be the result of warming temperature.

But researchers got to know that such might not be the case and penguins may have adapted better to the changing environment. With the help of the research findings, researchers concluded that emperor penguins might have not died in the 1970s, but would have just moved to different spots to breed.
