When female penguins return to the breeding site, they bring a belly full of food that they regurgitate for the newly hatched chicks. Emperor colonies also face blizzards of up to 200 km/h. Their nasal chambers also recover much of the heat that is normally lost during exhalation. Journal of Experimental Biology. Prvost J, Vilter V (1963). "Population size and breeding success of Emperor Penguins Aptenodytes forsteri at Auster and Taylor Glacier colonies, Mawson Coast, Antarctica". 32 At temperatures above 20 C (68 F an emperor penguin may become agitated as its body temperature and metabolic rate rise to increase heat loss. Contents, taxonomy, emperor penguins were described in 1844 by English zoologist.

42 Conservation status In 2012 the emperor penguin was uplisted from a species of least concern to near threatened by the iucn. While they mostly forage at depths of 150250 metres, the deepest dive recorded was to 565 metres.
