This trip again, we visited several Gentoo Penguin colonies. In contrast to Adelie Penguins, Gentoo Penguins are doing really well on the West Antarctic Peninsula. In many places, the Gentoo numbers are increasing. In comparison to Adelie Penguins, Gentoos are less dependent on sea ice for feeding. And with the temperatures going up slightly on the West Antarctic Peninsula, they slowly move further south, taking over colonies previously inhabited by Adelies.
