There are few certainties in life, but alongside death, taxes, and the arrival of hot weather in July, at least one other thing is inarguable: baby penguins are almost impossibly cute.
Guests visiting the Tennessee Aquarium during the Fourth of July holiday can join Aquarium staffers in excitedly welcoming the newest addition to the Penguins’ Rock gallery — a fluffy (and shockingly fast-growing) Macaroni Penguin chick.
The chick hatched on June 2 from an egg laid in late April by parents Bacon and Merlin. This baby bird is the first offspring ever produced by Bacon, who hatched in 2015 to two other Aquarium penguins, Hercules and Little Debbie. Though Little Debbie now lives at another facility, the newest chick’s grandsire, Hercules, still calls Penguins’ Rock home. With this latest arrival, the Aquarium is home for the first time ever to three generations of Macaroni Penguins.
The new chick is the Aquarium’s first hatchling since the 2021 arrival of Carla, a Gentoo Penguin. This latest baby is the first Macaroni Penguin chick since Pedro hatched in 2019. The Aquarium’s colony now has 23 birds: 9 Macaronis and 14 Gentoos.
The Aquarium’s keen-eyed penguin care team first noticed the egg pipping — that’s the cracking that occurs when a baby bird begins to chip away at its shell from the inside — on a Friday afternoon when they spotted a dime-sized hole with a tiny beak moving around inside. The new chick seemed to get cold feet on Saturday with little progress. However, by Sunday morning, the chick had fully emerged with an unusual level of precision that surprised even its veteran caregivers.
“It seems like it has a little type A personality,” says Assistant Curator of Forests Loribeth Lee. “It cracked the egg perfectly, straight down the middle. We’ve never really seen that.”
When Lee discovered the emerged hatchling, it was sitting in the center of its stacked shell, which was broken neatly around the side in an almost perfect circle.
The chick’s precocious attitude didn’t end there. So far, it has displayed confidence and fearlessness both in its nest and around caregivers when briefly removed for tri-weekly weigh-ins to monitor its health and rate of growth.
“We’ve seen it pick up rocks multiple times in the nest, which is very impressive that it can do that at its size,” Lee says. “It’s been throwing them around, so it’s a strong, tough little bird.”
Speaking of size, the chick has been growing at an astronomical rate, thanks largely to its parents’ diligence. A day after hatching, it weighed just 145 grams (5.1 ounces, or a little less than an iPhone 15). Three weeks later, it had ballooned to a whopping 1,592 grams (3.5 pounds). To put that in perspective, that’s the same as a 7-pound human infant weighing 77 pounds before it was a month old.
Lee credits those gains to the skillful parentage of Bacon and Merlin, who has fathered several previous chicks and kept the chick well fed. A penguin growing quickly isn’t all that unusual, though. Macaroni Penguin chicks must mature quickly to be ready for the harsh winters in their native Antarctic climates, where they reach adult size in just two and a half months.
