Rockhopper Penguin Chick Hatches at Shedd Aquarium


As if to say, "Hello world!" the newest Rockhopper Penguin hatchling waved its tiny wings for the camera at Chicago's Shedd Aquarium. Hatched just about a month ago, the chick is thriving and growing quickly, as penguins tend to do, before guests' eyes each day: Gaining weight, eating, and building relationships with its feathery neighbors on exhibit in the Polar Play Zone. The open nesting location there allows guests the rare opportunity to watch and learn about the chick as it develops and grows.

Visitors also have the unique chance to see the mother and father care for the hatchling, sharing parenting responsibilities in equal shifts. The experienced parental Penguin pair is feeding the bird well, according to Ken Ramirez, Executive Vice President of animal care and training for Shedd, but there are more key milestones ahead. The chick will learn to eat on its own before acquiring waterproof plumage and diving into its swimming skills for the first time.

Keepers observe and weigh the bird daily. Born at 75 grams, the chick gains approximately 40 grams per day and is now at a healthy weight of 1,019 grams. The gender of the chick has yet to be determined. It is difficult to identify gender in Penguins without genetic testing, as there is no observable difference in male and female anatomy.
