The discoveries come following a 30-year investigation where specialists tagged 50,000 individuals.
Scientists also observed the “divorce” of couples, and findings suggest that the cause may be the inability to produce offspring. In such cases, Penguins looked for new life partners. Others believe that personality incompatibility may also be a cause.
An important finding of this research is the life span of the relationship of individual couples. Beforehand penguin relationships were supposed to last only ten years. The main finding of the recent research is a couple whom relation lasted over 16 years. These makes Magellanic Penguin the most loyal wild species.
Every year Magellanic Penguins depart on solo journeys of 200 000 miles. When southern summer arrives, they return to their nest. They find each other by the use of a unique call. The researchers utilized satellite following to distinguish the developments of the feathered creatures, demonstrating the extraordinary voyages, up to 2000 000 miles, that they take every winter up north, to the hotter waters of Brazil in the Atlantic, and Peru in the Pacific Ocean.
In the wake of rejoining and mating, the female typically lays two eggs. Couple members will alternate to guard the eggs while the other goes to the ocean to fish.
After they incubate, the parents spend a month tending to their young before taking off to their wintering territory.
Patagonia, a territory divided between Chile and Argentina, have the biggest population, with 1 700 000 estimated nests.
It is important to mention that their numbers have declined since the turn of the century because of oil contamination and falling fish numbers.
Other species that mate for life include Albatrosses, Vultures, and Angelfish.
New Paths Expeditions explores Southern Patagonia in detail with its Epic Patagonia Expedition. An award-winning itinerary that includes Megallanic Penguin colony visits during nesting time.
The expedition crosses Tierra del Fuego to encounter King Penguins and interact with Argentinian Gauchos and then boards the Estella Australis ship and navigate the Beagle Channel to Cape Horn. Then sails the fjords of the Darwin Mountain Range and the Straight of Magellan to Punta Arenas, from where you drive to Torres del Paine National Park and lodge for four nights at the upscale Explora hotel, the best location in the park for a complete exploration of its highlights and hidden treasures. Horseback riding, trekking, birdwatching, puma search and many other activities are included. Open bar during the Australis Navigation and while at Explora hotel. Extensions to Easter Island, El Calafate, Perito Moreno, El Chalten, Santiago de Chile and Buenos Aires are available.
