Gentoo penguins raising their young
When a chick became apparently very hungry, it would start waving it's arms around and squawk in a higher pitch than the parents, and sometimes it would look around almost as if it were ready to leave the nest and go off on its own in search of food.
Occassionally, a parent would move toward another nest, and the encroached parents would stick out their heads and beaks at it and squawk, warning it off. Sometimes, a parent would leave the nest and go in search of food (in the water) or rocks (nestled between larger rocks in the open areas of the island).
The cormorants were ever-present as well, mixing in with the penguins so well that it sometimes took a moment to realize that the bird one was looking at wasn't a penguin after all.
