Penguin Huddle (VIDEO)

PLOS

Caption

This movie shows about half of the penguin colony during the aggregation and huddling process. At the beginning of the movie (,12 p.m. with temperatures above 235uC), only few penguins aggregated in smaller huddles. As the temperatures gradually fell, larger and more stable huddles formed until nearly all the penguins aggregated in one large huddle.
