Mondika is turning one in August, and she continues to do wonderfully within her family group! It is extremely important for a young gorilla to grow up in their family group to learn how to be a gorilla. As she is growing more aware, she is learning the social dynamic of her family by hearing vocalizations, seeing interactions between members and even by smelling different smells. Asha is her primary teacher and has been a wonderful mother, being very attentive and protective of Mondika (Mona). Asha enjoys grooming and playing with Mona and lately is allowing Mona to become more independent by venturing off some, but not out of reach at this point.
Mona is also very interested in learning from other members within her family like her father, Jomo. Jomo is not only an excellent silverback, he is also a wonderful dad. Mona is Jomo’s second child and continues to prove himself. He is reserved, respectful and gentle with Asha and Mona. Mona is very interested in him and has been seen on several occasions touching, climbing and smelling him. Jomo sits very still and enjoys every minute. As Mona grows more playful and independent she will most likely spend more time with Jomo.
Physically she is also progressing well as a young gorilla. She is still small as gorillas grow slowly like humans do. They are considered babies until they are three years old. Therefore, she spends most of her time on mom, but every day she is growing more independent. As a result, she has learned to knuckle walk and climb and enjoys hanging upside down. She has also developed a white dot on her rear end that all gorilla babies do. They are not born with this white dot and it does disappears as they get older. This dot allows their mom to see them more easily in the dense dark forests in the wild as they start to venture off.
Mona is curious and aware of her surroundings and food. She now has enough teeth to explore foods that mom eats. She has a sweet tooth, like most primates, and enjoys bananas and grapes the most. However, she still nurses frequently and her mothers milk is her main source of nutrition at this age. Mona will continue to become more adventurous and playful, and her personality will become even more apparent as she continues to grow within her family group. As keepers we are excited to see her develop socially and physically.

Glass Glass Baby: Birth of Healthy Kittens following Sperm Vitrification for Artificial Insemination
A world leader in small cat reproductive research, our Center for Conservation and Research of Endangered Wildlife (CREW) has successfully produced the first non-human offspring – two kittens – using vitrified sperm (semen preserved as glass instead of ice) for artificial insemination (AI). Dr. Bill Swanson explains the significance of this breakthrough in this video.
Cryopreservation of cat semen for assisted reproduction can be challenging, requiring technical expertise and specialized equipment for semen collection, processing and freezing. As a simplified alternative to standard semen cryopreservation methods, CREW scientists have been investigating the use of vitrification – the ultra-rapid cooling of liquids to form a solid without ice crystal formation. This approach essentially preserves semen as glass instead of ice.
For vitrification, cat semen is diluted in a chemically-defined medium containing soy lecithin and sucrose as cryoprotectants and, after a five minute equilibration period, pipetted in small volumes (~30 microliters) directly into liquid nitrogen to form tiny glass marbles of frozen sperm.
In initial studies, we found that cat sperm survived vitrification as successfully as that frozen using standard straw freezing methods and that vitrified sperm were capable of fertilizing cat oocytes in vitro. In our first assessment of in vivo viability, eight of these embryos were transferred into three synchronized females. Although one female appeared to have two early implantations, no offspring were produced.
In a follow-up study, artificial insemination (AI) with vitrified sperm was assessed in three additional females. With our laparoscopic oviductal AI technique (LO-AI), only a couple million sperm are required per insemination, allowing the use of the relatively low sperm numbers that are preserved in vitrified semen pellets. Following LO-AI with vitrified sperm, all three females conceived, with two of the pregnancies progressing to term and culminating in the birth of two healthy kittens in early April. These kittens, a male named Vito (short for vitrification) and a female named Elsa (after the character in the movie Frozen), are the first non-human offspring – of any species – produced with vitrified sperm (although three human babies have been born from earlier research).
Our preliminary results with semen from fishing cats and ocelots indicate that vitrification is effective for preserving post-thaw sperm viability and function across cat species. These findings suggest that this fast and simple cryopreservation method may have broad applicability for semen banking of endangered felids housed in zoos and possibly living in the wild.
The study’s lead author, veterinary student Jaci Johnson, has been selected to present these findings at the upcoming American Association of Zoo Veterinarian’s Annual Meeting in Portland, Oregon.

The pups are out! The pups are out! It’s been a long time waiting for the weather to break so the African painted dog pups could come outside. For the past few months, only their keepers were allowed to access the holding area. As soon as the rest of us employees heard the pups were finally out, many of us made a beeline for the exhibit like giddy schoolchildren on a field trip!
As I sat and marveled at the antics of our 10 boisterous, playful pups exploring their outdoor yard for the first time, my thoughts wandered to what it would be like to actually see painted dogs in the wild. I’ve been fortunate to travel to Africa a few times—once to lead an Earth Expeditions course in Namibia, another time to lead a course in Kenya, and also to pick up my daughter whom we adopted from Ethiopia. Each time, I experienced amazing landscapes and wildlife from hippos to rhinos to lions, but never did I encounter painted dogs. This isn’t surprising considering the African painted dog is one of the most endangered carnivores in Africa.
If I were to travel to Africa with the goal of seeing painted dogs, Ruaha National Park and the region surrounding it in Tanzania would be the place to go. Not only does the third largest population of painted dogs live there, it’s also the home base of the Ruaha Carnivore Project (RCP), a conservation program that the Zoo supports. RCP works with local communities to ensure the survival of carnivores and people in the region.
As it happened, the same day the pups first went out on exhibit, we also had a visit from RCP’s Director, Amy Dickman, who updated us on the latest news on the project. Amy is phenomenal and a very charismatic and inspiring leader, so much so that she was one of three international finalists for the prestigious Tusk Conservation Award last fall. This award recognizes individuals who have undertaken outstanding, inspirational conservation work throughout Africa. Although Amy did not win the award (this time), she did get to have afternoon tea with Prince William and it generated a lot of attention for the project, including this fabulous short film.
As mentioned in the film, Amy has done a fantastic job winning the trust and participation of the local Barabaig people. It used to be one of the few ways to gain status and wealth in the tribe was to kill lions, but that’s changing. RCP has found a way to provide tangible benefits of protecting carnivores to the community. RCP provides education scholarships and materials, veterinary supplies and health care clinics, and those villages that can show they have the most wildlife in their area receive the greater rewards.
How exactly do they determine which areas have the most wildlife? It’s ingenious, really. RCP has started giving villagers their own camera traps and training them how to set up and manage them. For each predator or prey species captured on camera, they receive a certain number of points – 2,000 points for an eland, 3,000 for a hyena, 4,000 for a lion, 5,000 for a painted dog, and so on. And if the picture has a whole pack of painted dogs in it like the one below, they get 5,000 points for each individual dog!
Villagers are now more motivated to find ways to coexist with carnivores. Instead of killing carnivores to keep them from attacking their livestock, for example, they are building better bomas, or corrals, and using guard dogs to prevent depredation.
In just five years, Amy’s work has resulted in a 60% decline in livestock depredation, a significant rise in people recognizing benefits from wildlife, and most importantly, an 80% decline in carnivore killing. Amazing! As RCP looks to the future, I hope the Zoo continues and strengthens its relationship with the project.
As for me, I may never see African painted dogs roaming the African savannah (though I’m not giving up hope), but knowing that we support great programs like RCP makes me optimistic about their future in the wild. For now, I am content to watch our pups trip over their paws and grow into their giant ears here at the Zoo. I hope you will join me!
p.s. The Zoo sponsors one of RCP’s field cameras. In return, RCP posts images taken by our Cincinnati Zoo Cam on a dedicated Facebook page; like the page to follow along!
