Hatched on 19 April 2007 at the Academy, “Domino” is becoming sexually mature. Imagine a  human between ages 13 and 21, with hormonal changes, social challenges and first dates. ”Domino” is showing these characteristics through fighting for territory, displaying towards a female penguin “Pomona” and biting me when I come close.  He will eventually settle down in a nest and from a very strong permanent bond with a female penguin. Until then, he will continue to challenge birds and biologists.-Pamela Schaller
