Gentoo penguins are adorable. especially the little grey and white fluffy chicks. These photos were taken at Paulet Island and at Brown Bluff , both located at the tip of the Antarctic peninsula. They are relatively small, 10 - 18 pounds, and porpoise when they are swimming. They have a white marking above their very dark brown eyes. They build a nest of rocks onto which the mother lays her eggs and lies atop them to keep them warm.
