Rhino Awareness Days
World Rhino Day falls on a Tuesday this year, September 22, so the Zoo is going to celebrate Rhino Awareness Days, free with regular Zoo admission, the following weekend. From 10:00 to 3:00 on September 26 and 27, guests are invited to learn more about rhinos and how we can help save them in the wild.
CREW Volunteers will be on hand at the Sumatran rhino exhibit to tell Harapan’s story, the last Sumatran rhino on exhibit in the United States. Here guests can catch a last glimpse of Harapan before he leaves for Indonesia and wish him well on his journey. With less than 100 Sumatran rhinos left on Earth, Harapan will move to the Sumatran Rhino Sanctuary where he will have the opportunity to breed and contribute to his species’ survival. His departure marks the end of an era for the Cincinnati Zoo’s Sumatran rhino breeding program, the only captive breeding program in the United States to produce calves for this critically endangered species. An exact date for Harapan’s departure has not been set, but the Zoo is pushing for the move to happen this fall. Until then, guests can visit him in Wildlife Canyon daily from 9 a.m. – 12:30 p.m., weather permitting.
Speaking of Harapan’s departure, there’s exciting news about his brother, and Cincinnati Zoo born Sumatran rhino, Andalas. The critically-endangered Sumatran rhino population will soon increase by one. In a species with fewer than 100 individuals left on the planet, one is a significant number. Andalas and Ratu are expecting a calf in May 2016. Learn more and see ultra sound images here.
On the other side of the Zoo, guests can engage with Volunteer Educators at the CREW Wild Discover Zone to learn more about all of our rhino research programs. CREW is currently undertaking a project to expand access and build capacity for African and Asian rhino reproductive care within North American zoological facilities. The Zone is set up next to the Indian and black rhino exhibits where guests might get the chance to say hello to our newest rhino resident, a black rhino male named Faru.
Faru is doing great here in his new home and his training is going very well. The keepers are working with him to present both sides of his body on cue and open his mouth to allow them to check his teeth and tongue. This allows them to perform basic foot care, daily baths, and administer medical care when needed with minimal stress to Faru. He and the female, Seyia, are still getting to know each other, and the hope is to put them together for breeding later this fall.
The keepers are also working with CREW to determine the reproductive cycle of our one and only Indian rhino, Manjula, using ultrasound and urine analysis. Manjula is chute-trained, target-trained, and she will hold her mouth open while they shine a flashlight inside to check everything. This training has been essential to administering the hormone to help her ovulate and also give the anesthetics used for her standing sedation procedures- both of which she does willingly and cooperatively! The plan is to artificially inseminate Manjula. The keepers are also currently working on blood draw training and teaching Manjula to stand her rear feet in rubber tubs for a foot soak. (Indian rhinos are prone to foot issues.)
Bowling for Rhinos
What else can you do to help save rhinos? Go bowling! The Greater Cincinnati Chapter of the American Association of Zoo Keepers is holding its second annual Bowling for Rhinos event on October 17 to raise awareness and funds for rhino conservation.To be held from 6:00 to 8:30 at Stone Lanes in Norwood, the event is sure to be tons of fun! In addition to bowling, there will be t-shirts for sale, a silent auction and a raffle to meet a rhino at the Cincinnati Zoo! Buy your tickets online now before they sell out!

In September, the Zoo’s Center for Conservation and Research (CREW) was awarded a National Leadership Grant from the Institution of Museum and Library Services in support of a Rhino Assisted Reproduction Enterprise (RARE) initiative for Indian rhinos and African white rhinos. Dr. Monica Stoops will be the Project Director for the grant work and will be working in partnership with Dr. Justine O’Brien from the SeaWorld & Busch Gardens Reproductive Research Center (SWBGRRC), which includes a state-of-the-art sperm sorting and cryopreservation laboratory. CREW will undertake the project to expand access and build capacity for African and Asian rhino reproductive care within North American zoological facilities. Eight zoos have committed to building a Rhino Assisted Reproduction Enterprise (RARE) in collaboration with CREW. This project will help 1) contribute to the genetic management and propagation of captive Indian rhinos through artificial insemination (AI); 2) enhance southern white rhino fertility through exogenous hormone administration prior to natural breeding or AI; 3) build upon national rhino gamete rescue centers at CREW and SWBGRRC; and 4) provide collaborating facilities with individualized training and/or support in rhino assisted reproductive technology (exogenous hormone protocols, ultrasonography, endocrine analysis, AI, and sperm collection, sorting and cryopreservation).
One part of the proposed research will be to continue and expand upon a preliminary CREW investigation conducted to develop an exogenous hormone protocol to initiate reproductive activity in previously acyclic southern white rhinos. The African white rhino remains the most popular rhino species held in U.S. zoos (although we do not currently house them here in Cincinnati). Although captive breeding has been successful and a sufficient number of calves are being produced to consistently maintain the population, the proportion of breeding recommendations resulting in offspring is quite low. It is estimated that <30% of all wild born and <20% of captive born African white rhinos have reproduced in captivity. These numbers reflect a major impediment to achieving a sustainable captive breeding program for this species.
A primary reason for the low reproductive rate is that a vast majority of females display long periods of acyclicity. Significant progress has been made in initiating reproductive activity in acyclic white rhinos in Europe using exogenous hormones. However, many drugs used overseas are not commercially available in the United States. Therefore, it became necessary
to develop novel hormone protocols using U.S. drugs to similarly promote a resumption in reproductive activity for acyclic white rhinos.
CREW scientists, in partnership with several North American zoos, embarked on a preliminary exogenous hormone trial in which four acyclic female white rhinos were treated. Females responded by growing preovulatory follicles, but did not stand for breeding by a male and required an additional hormone to ovulate. This initial hormone protocol may be adequate should artificial insemination be performed, but CREW scientists and partner zoos are working to develop an alternative hormone protocol that will result in natural mating so that more individual rhinos and institutions will benefit. By enhancing the fertility of captive African white rhinos, CREW is helping to ensure the sustainability of this rhino population.

Over the past year, Zoo staff and volunteers have been getting ready to celebrate World Rhino Day. This year’s festivities will be held from 10 am to 4 pm on Sunday, September 21. The goal for this event is to raise funds for rhino conservation and increase the public awareness of the major challenges faced in protecting wild rhino populations. The Zoo is proud to exhibit three species of rhino; the African black rhino, the Indian rhino and the Sumatran rhino. Zoo visitors can take part in family activities, animal demonstrations, keeper encounters and a rhino-riffic raffle. The day will start with the official announcement of the winners for our Save the Rhinos poster contest. The day will no doubt be a Rhinotastic success!
The raffle items this year include rhino-themed gift baskets, a one-year membership to the Cincinnati Zoo & Botanical Garden, Rhino Rembrandt paintings artistically designed by the Zoo’s African black rhino ‘Seyia’ and Sumatran rhino ‘Harapan’, a one-of-a-kind Sumatran rhino footprint casting created by keeper and artist Lindsay Garrett, and an amazing print of Sumatran rhino ‘Harapan’ as designed and painted by artist Ali Armstrong as part of her ‘Scarce Project’.
Be sure to also come out to the Zoo on Monday, September 22, from 7-9 pm to hear the State of the Rhino Lecture by CREW Rhino Scientists Dr. Terri Roth. Tickets to Dr. Roth’s lecture can be purchased online. A rhino marketplace will take place in the lecture hall before and after the talk and another rhino raffle occur. In addition, renowned children’s book author Mary Kay Carson and photographer Tom Uhlman will be available before and after the lecture to sign copies of their critically acclaimed book, Emi and the Rhino Scientist.
Come one, come all to help us celebrate rhinos!
