The Tennessee Aquarium’s gentoo and macaroni penguins are busy birds. Check in on their playful antics any time you could use a little “penguin break.” Throughout the year, you’ll witness courtship, nest building, rearing young and molting at the Aquarium.
Penguins’ Rock is presented by Little Debbie.

Annual Penguin "Molting"
Gentoo and Macaroni Penguins replace all of their feathers every year in a single molt (aka "catastrophic molt"). To prep for this annual event, the birds spent the preceding weeks eating huge amounts since they can't swim while molting.
During the two- to three-week period of the molt, the birds' new feathers push out the old ones, and they tend to look a little ... scruffy ... as a result. Once complete, however, the birds are much happier (and begin swimming and eating again, as usual).
