Seyia arrived at the Cincinnati Zoo & Botanical Garden in August of 2013 and is currently the only black rhino we have here. She made the long journey all the way from Baton Rouge, Louisiana, where she was born. Seyia will celebrate her fifth birthday on September 28.
The black rhino, or hook-lipped rhino (Diceros bicornis), is native to eastern and central Africa. Black rhinos are generally solitary animals, except for mothers with calves. However, males and females have a consort relationship during mating, and sometimes young adults will form loose associations with older individuals of either sex.
An herbivorous browser, black rhinos eat leafy plants, branches, shoots, thorny bushes and fruit. You will often see browse, or large leafy branches, in Seyia’s exhibit, which is one of her favorite things. She also loves bananas, apples, kiwi and melon. We often utilize these items for her training sessions and as enrichment scattered throughout her enclosure. On special occasions, we might even give her whole watermelons to smash and eat.
Every rhino has its own personality and Seyia is a real sweetie, yet definitely has some sass and spunk to her. She loves attention – getting a good rub down, taking a bubble bath, and most of all, interacting with her keepers during training sessions.
Seyia has learned so much over the past year here in Cincinnati. We train all of our animals to do lots of different husbandry behaviors, which helps us provide them with the best care possible. This is especially important when caring for rhinos. The black rhino has a reputation for being extremely aggressive, charging readily at threats. They have even been observed charging tree trunks and termite mounds in the wild! So it takes a very strong bond between keepers and their rhinos to accomplish all that we need to do with them. Only once this trust is formed between keeper and rhino can training begin.
We began the process by hand-feeding her lots of her favorite treats. After that, we began target training and moved forward from there. Seyia has now learned to move either side of her body up against the side of her indoor enclosure. This allows us to get a good look at her, bathe her, and even apply a Skin So Soft solution to help keep her skin moisturized and keep the flies away. She can place either front foot on a block for nail and foot care and is also trained to lay down on command. Right now, we are working with her on opening her mouth so we can check out those pearly whites. Not only is all this training useful for husbandry and medical care, it’s also a form of enrichment for her.
Seyia, often referred to as “little girl”, is not so little anymore! In fact, as of December 2013, she weighed in at a whopping 2,400 lbs. She is due to be weighed again this fall, and I guarantee she’s grown. Her body and horn are much bigger than when she first arrived.
How do we weigh a rhino? We use a set of truck scales. Our Maintenance department constructed a heavy duty “weight board” that we carefully place over the scales and the rhino can just step on up. We feed her some of her favorite snacks while we watch the number going up until we have an accurate weight. We do this a few times just to be extra certain it’s accurate. This is not only important to ensure a healthy weight, but also for our veterinary staff to know in case of an emergency or if they need to prescribe her any medications.
Next time you are at the Zoo, be sure to stop by the black rhino exhibit in Rhino Reserve (across from LaRosa’s) to see Seyia. Also, be sure to come out for World Rhino Day on September 21 to celebrate and support rhino conservation efforts here at the Zoo and across the globe.

CREW has done it again! We are excited to announce the birth of a female Indian rhino calf produced by artificial insemination (AI) conducted by CREW Reproductive Physiologist, Dr. Monica Stoops, and born on June 5 at the Buffalo Zoo. From a historical standpoint, this is the first offspring for a male rhino who never contributed to the genetics of the Indian rhino population during his lifetime – a major victory for endangered species around the world and a lifetime of work in the making.
The father, “Jimmy,” died at the Cincinnati Zoo in 2004. Over the course of those ten years, Jimmy’s sperm was stored at -320°F in CREW’s CryoBioBank™ in Cincinnati, before it was taken to Buffalo, thawed and used in the AI.
“We are excited to share the news of Tashi’s calf with the world as it demonstrates how collaboration and teamwork among the Association of Zoos & Aquariums (AZA) organizations are making fundamental contributions to rhino conservation,” said Dr. Monica Stoops. “It is deeply heartening to know that the Cincinnati Zoo’s beloved male Indian rhino, Jimmy, will live on through this calf and we are proud that CREW’s CryoBioBank™ continues to contribute to this endangered species’ survival.”
“Tashi,” the Buffalo Zoo’s 17-year-old female has previously conceived and successfully given birth through natural breeding in both 2004 and 2008. Unfortunately, her mate passed away and the Buffalo Zoo’s new male Indian rhino has not yet reached sexual maturity. Because long intervals between pregnancies in female rhinos can result in long-term infertility, keepers at the Buffalo Zoo knew it was critical to get Tashi pregnant again and reached out to Dr. Stoops for her expertise.
In February of 2013, Dr. Stoops worked closely with Buffalo Zoo’s rhino keeper Joe Hauser and veterinarian Dr. Kurt Volle to perform a standing sedation AI procedure on Tashi. Scientifically speaking, by producing offspring from non or under-represented individuals, CREW is helping to ensure a genetically healthy captive population of Indian rhinos exists in the future. This is a science that could be necessary for thousands of species across the globe as habitat loss, poaching, and population fragmentation (among other reasons) threaten many with extinction.
The Buffalo Zoo staff monitored Tashi’s pregnancy over the 15-16 month gestation period and at 3:30 p.m., on June 5, she gave birth to a healthy female calf, weighing 144 pounds.
“Without Dr. Stoops’ dedication to the species, and to the development of AI science, there is no doubt this calf would not be here today,” said Hauser. “She has spent countless hours spear-heading research and technology for Indian rhino conservation and the Buffalo Zoo is excited to acknowledge that dedication and announce that the name of the calf is “Monica.”
Tashi’s calf demonstrates that AI science is a repeatable and valuable tool to help manage the captive Indian rhino population. With only 59 Indian rhinos in captivity in North America and approximately 2,500 remaining in the wild, being able to successfully introduce genetics that are non or under-represented in the population is critical to maintaining the genetic diversity necessary to keep a population healthy and self-sustaining.
“We are always thrilled to welcome a new baby to the Buffalo Zoo, but this birth is particularly exciting because the science involved is critical to saving endangered animals,” said Dr. Donna Fernandes, President of the Buffalo Zoo. “This type of professional collaboration among AZA Zoos is vital to the important work we do as conservation organizations and we are honored to play a critical role.”

Zoo guests may have noticed that John the lion has not been in his yard for the past couple of days. He’s been absent for a very good reason! On Wednesday, we opened the doors that separated John and Imani and introduced the male and female lions to each other for the first time!
This introduction has been a long time coming; several months of close monitoring and careful preparation have led up to this big moment for our young lions. For the last year, John and Imani have been living in separate enclosure areas. Typically John was housed in 2 indoor enclosures and had access to our exhibit yard. Imani was being housed in 3 indoor enclosures (across the hall from John), and had access to her own private play yard as well. Though the lions could see, hear and smell each other on a daily basis, they’d never met in the same space until now.
In order to ensure a successful first meeting, keepers wanted to be sure that both lions were fully grown, sexually mature, and confident and comfortable in their new homes at the Cincinnati Zoo before the lions began to share a territory. Additionally, keepers had to plan an introduction timeline that would be conducive to the potential birth of cubs (since John and Imani are a recommended breeding pair within the African lion SSP). An SSP, or Species Survival Plan, allows different zoological facilities to cooperatively manage specific, and typically threatened or endangered, species populations. In order to receive a breeding recommendation for two animals, SSP coordinators assess the representation of each animal’s genes within the captive population. If the genes of both individuals are not overly represented among the captive population, and if there is a zoo with the space to house the offspring, then you get the “okay” to breed the pair. Utilizing SSPs allows zoos to ensure that we are maintaining as much genetic variation as possible among captive populations, and also avoiding inbreeding and unwanted pregnancies.
With warmer weather on the horizon and both lions showing positive indicators that they were ready to meet, the keepers determined that the time was right to introduce John and Imani. Initially, both cats were a little shy and hesitant to say hello, but after a few minutes of awkward, sideways glances, John came through the door for a sniff. Some grumbles, barks and swats ensued (perfectly normal and expected behaviors), and then both lions quickly settled down and even made some attempts at breeding!
The two have been spending time together behind the scenes ever since, and the keepers are absolutely thrilled with their progress. John and Imani will slowly be introduced to the exhibit yard together according to their comfort level. While John is perfectly at home in the exhibit yard, Imani has not been out there yet, so we will respect her need to move forward slowly. Her comfort level will likely dictate when our lions will be publicly on exhibit together, and we appreciate everyone’s patience and understanding during this transition period.
On behalf of our lions, and all the keepers and staff involved, thank you all for your support and well-wishes! Our zoo guests have been so great about accepting John into the Zoo family, and we can’t wait for you all to meet Imani and see our newly bonded pair out on exhibit together soon!
