Emperor Penguins Shift Nesting Place due to Climatic Conditions
Global warming could be the reason forrelocation of nesting placefor some of the emperor penguins in the Antarctic Peninsual, said researchers from University of Minnesota (UM). The research team revealed that penguins shift their nesting places due to change in environment conditions, resulting in melting of ice sheets.
These flightless birds are even more adaptable and smarter that ever thought, said Michelle LaRue, lead researcher from University of Minnesota College of Science and Engineering. On studying a new colony of emperor penguins in the Antarctic Peninsula, researchers have found that penguins keep on migrating with change in environmental conditions throughout the year.
"Penguin colonies seem to appear and disappear throughout the year's challenges behaviors we thought we understood about emperor penguins", said Michelle. Pointe Géologie, also termed as emperor penguin colony, has been under observation for the past 60 years. Earlier, it was believed that penguins return to the same place every year to make nests, but the current research has proved it wrong.
About 50% declines in penguin population were reported in late 1970s due to increase in warming conditions. The report raised fear among many scientists claiming the penguins would not be able to survive in few decadesincreasing warming conditions. The current study suggests that penguins are adaptable and some penguins shift their location. With help of high resolution satellite images, the research team tracked the location of penguins in the region and along the coastline.
In the latest conference held at IDEACITY in Toronto, researchers concluded that penguins change their locations with respect to change in environmental conditions. Gerald Kooyman, from University of California San Diego, Heather J. Lynch, from Stony Brook University and Peter Fretwell, from British Antarctic Survey also contributed their share in conducting the research.
