WASHINGTON-in the last three years have virtually no born offspring of Emperor penguins in its second largest in Antarctica breeding grounds, and the start of this 2019 seems just as gloomy, according to a new study. Usually between 15,000 and 24,000 pairs of Emperor penguins go each year to a breeding ground considered safe at the Halley Bay and that will keep ice cream this century despite global warming. But almost no chicks are recorded in the area from 2016, according to a study published Wednesday in the journal Antarctic Science.La population of mated pairs has increased considerably in another close play area, but the author of the study said that the births of penguins in this place do not compensate for the shortfall at the Halley Bay.” We have never seen a failure of this scale replica in 60 years”, said the author of the study, Phil Trathan, head of conservation at the organism biology British Antarctic Survey. “It’s unusual to have a total failure of reproduction in a big colony.” Normally, around 8% of the population of penguins Emperor of the world are born at the Halley Bay, Trathan said.
Penguin species, the Emperor is the largest, weighing up to 40 kilograms (88 pounds) and live about 20 years. Their plumage is black with white, and the ears and the top of the chest have yellow tone. Couples are reproduced in the most severe winter conditions and the male is that incubated the egg. The scientists attributed the sharp decline to climatic and meteorological conditions that break the “permanent ice” ice of the sea connected with the land where the emperor penguins remain to be played. They incubate their eggs and care for their offspring a for couple on the ice. After reproduce and care for their chicks, penguins head to open sea.
