   Explanation: A male Adelie penguin performed this Ecstatic Vocalization
   in silhouette during the [5]December 4 solar eclipse, the final eclipse
   of 2021. Of course his Ecstatic Vocalization is a special display that
   male penguins use to claim their territory and [6]advertise their
   condition. This penguin's territory, at Cape Crozier Antarctica, is
   located in one of the largest Adelie penguin colonies. The colony has
   been studied [7]by researchers for over 25 years. From there, last
   December's eclipse was about 80 percent total when seen at its maximum
   phase as the [8]Moon's shadow crossed planet Earth's [9]southernmost
   continent.
