New African Penguin Juveniles!

It takes two… more African Penguins, that is!


The National Aviary’s adorable African Penguins chicks have reached a MAJOR milestone! Both siblings – now sporting their juvenile sleek gray, waterproof feathers – have joined the rest of the Penguin Point colony! 

AND they have extra-special names….. 

Hatchling One is…

Dave was named by Aviary supporters Jacklyn and Josh Banyas as well as Megan and Kevin Wolfe in honor of Jacklyn and Megan’s dad, Dave McCluskey. 

Hatchling Two is…. 

Rita Mae was named by Aviary supporters Michael and Lisa Hart in loving memory of their aunt, Rita Mae Caste.

To commemorate the naming as well as the duo’s official entrance to the Penguin Point habitat, we invited the supporters to unveil their names before the daily 10:30 am feeding (an activity that is included with admission!).

Watch Dave and Rita Mae join Penguin Point!

You can visit Dave and Rita Mae now or during our new seasonal theme, Colors in Flight, which starts May 26!

Gender Reveal

To commemorate our “gender reveal,” we involved our resident artist, Valentino, the Linnaeus Two-toed Sloth! Using his natural ability to grasp and move objects, he painted two canvases of African Penguin silhouettes using animal-safe paint and stencils.

During the reveal, the African Penguin duo completed a check-up exam and weigh-in. On average, African Penguin chicks take about three months to grow into their adult size. Both are extremely healthy and developing as their care team expects them to. But it’s not just about their physical health; we are learning more about these dynamic birds’ personalities.
In addition to seeing positive developments in their health and growth, the sibling pair are already displaying their unique personalities! Both juveniles are naturally inquisitive, out-going, and love exploring their environment. They’re learning the essential skills to grow up and behave very similar to their parents (Patrick and Owen),” says Dr. Pilar Fish, Senior Director, Zoological Advancement & Avian Medicine.  

As for what’s next for this duo?

“Our amazing veterinary and animal care staff at the National Aviary have been instrumental in ensuring the fantastic growth and development we continue to witness with the sibling pair,” says Kurt Hundgen, Senior Director of Animal Care and Conservation Programs. “Once the juvenile penguins can feed on their own without the help of their parents, they will be ready to join the colony in Penguin Point. We remain optimistic that that this will happen in late April around World Penguin Day (April 25). During their transition into the habitat, we will also announce their names!

Exciting Hatchings for an Endangered Species at the National Aviary

In 2022, the National Aviary announced the hatching of Pierogi, an exciting new addition to the Penguin Point African Penguin colony. Just a little over a year later, we are thrilled to share that Pierogi’s biological parents, Patrick and her mate, Owen, have hatched two additional African Penguin chicks! Pierogi and his new siblings mark an additional spark of hope for a species that is increasingly experiencing population declines in the wild.

Because of the critical importance of each and every hatching for this endangered species, Pierogi was raised by Patrick and Owen’s colony mates, Sidney and Bette, who have so far fledged 10 chicks at the National Aviary. This time around, Patrick and Owen incubated their two eggs inside of a Penguin Point nesting cave for about a month and the chicks hatched on November 5 and 9.  An excellent genetic match, they are already showing strong signs of being dedicated penguin parents. The National Aviary’s expert animal care team has been observing their feeding, brooding, and preening behaviors, and can see that these chicks are growing and developing well in their care, now in a behind-the-scenes habitat so that they can be closely monitored by the veterinary team.

African Penguins reach their adult size at about three months old. They generally grow to be about 18 inches tall and can weigh up to 10 pounds. African Penguins are monomorphic, meaning males and females are visually similar; the Aviary veterinary team will conduct a DNA feather test on both chicks to determine their sex once they reach adult size. 

Importance of this Hatching

The National Aviary is the leader of the AZA: Saving Animals From Extinction (SAFE) program for African Penguins. The program is coordinated by National Aviary Senior Conservation Scientist Dr. Patty McGill, who works with colleagues at the Aviary and around the world to identify and address the short-term and long-term challenges plaguing the species. Due to the overharvesting of fish, disasters like oil spills, climate change, and lack of appropriate places for existing penguins to nest, it is predicted that African Penguins could be functionally extinct in the wilds of Southern Africa by 2035.

How We Help

Today, less than 3% of the historic African Penguin population exists, with only about 9,000 pairs remaining in the wild. The ever-growing African Penguin colony that resides at the Aviary has allowed us to implement new and innovate ways to promote our conversation efforts, such as making use of artificial nesting burrows onsite, offering additional nesting opportunities to our colony. With this research in hand, the National Aviary, in collaboration with partner organizations, has been able to provide 1,500 artificial nesting burrows throughout six Southwest African colonies.
