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. Watch as the Penguin chick interacts with its trainer below:
