Right now the macaronis are a surly group. Their in the middle of their molt which naturally causes them to be grumpy. Unfortunately, a youthful gentoo found out the hard way that you don't go barging into a molting macaroni's nest uninvited. Aldrich had to intervene when Hercules, seen above, tried to give the wandering chick a piece of his mind with the business end of his beak.
Back among friends with the other gentoos, this clumsy little penguin explored the exhibit introducing himself (or herself) to the other birds.
Even though this toddler weighs around 13 pounds, he or she appears to be wearing baggy pants. According to Aldrich, the "pants" will fit better as soon as the chick starts swimming. As the breast muscles develop, this loose appearing skin will "fill in."
