Gentoo Penguins Build Rock Nests on the Antarctic Ground

Gentoo Penguin's chick hatching structure does not look like a nest at all. The so-called Gentoo penguin nest, known as its scraper from its simple structure, is refined as long as the Antarctic landscape permits. The breeding pair made a small rock fort and arranged feathers and moss before egg laying. During breeding season the rocks that make up the nest are protected from colonial neighbors. If there is an objection to the ownership of a particular jewel, a noisy conflict will occur. The chick has been in the nest for about 1 month before heading to the sea

A small stone nest is made to divide the dent on the ground. Some beards and ghosts use stones to make nests. When the snow is extruded from melted snow, these stones will help keep the eggs on the surface. Adelie, gentoo, beard penguin is well known to remove stones from other nests. Penguins back to the nest sometimes use his partner as a stone for courtship ... medium size gentoo nest consists of 1,700 pebbles and 70 mink tail feathers. Antarctic researcher Guillaume Dargaud (he said "I lived with a penguin for over a year", but "I can not replace a true avian scholar") talked about Adélie and Emperor's penguins I talk about rumors on a comprehensive page. Dargaud believes that the rumor is a myth of Adelie penguin's nesting habits and that the inclusion of pebbles is accurate, but any pebble is sufficient for the purpose of spouse evaluation.

Another Antarctic penguin under the influence of global climate change is Adelie penguin. Unlike Emperor Penguins, Adri does not keep chickens with sea ice. Instead, it made a pebble stone in a sparse area of ​​the Antarctic coastline. In the western part of the Antarctic Peninsula, as the temperature rises it allows the air to hold more water, which leads to more snowfall. 7 Because the snow-free nesting site can not be found, the number of Adelie penguin populations is decreasing rapidly8. The disappearance of winter sea ice in this area has also adversely affected Adley's food supply 9. More ice-tolerant people, more chin straps and Gentoo penguins extend south to the Adelie breeding ground of the Antarctic Peninsula on behalf of Adelie penguin 10.

Although less common, it is that climate change seems to benefit several penguin populations. Gentoo Penguins extended the range by withdrawing the heavy ocean sea ice in the southern hemisphere western part of the Antarctic Peninsula (Lynch et al., 2012) and the retreated link is related to the expansion of Adélie penguin colony at Rose Beaufort Island (La Rue et al) Al. 2013). Still, future predictions may be more complicated than previously thought. For example, the feeding efficiency of Adelie penguins in the Ross Sea may be affected by extreme weather phenomena that disturb plasticity of the penguin population response (Lescroëlet al., 2014). This suggests that the predictive power of relationships established in past observations (as well as the average climatic conditions as well as the frequency of extreme climate abnormalities) may not be a good predictor of future climate change reactions There.
