This week, we at the Cincinnati Zoo are celebrating Earth Week! Earth Week surrounds Earth Day, an annual worldwide event where we recognize and support environmental protection and conservation efforts across the globe. In the midst of work on the Passenger Pigeon Memorial renovation, I can’t help but think of Martha, the world’s last passenger pigeon, during this week, almost 100 years after her passing. Despite the loss of this species, Martha’s legacy and the occasion of Earth Week provide us with a great opportunity to think about how we might protect other species today.
Not only can you learn more about conservation programs at the Cincinnati Zoo, you can get involved in species conservation in your own backyard! There are many programs specifically targeted toward bird lovers, which we will highlight this week in honor of Martha.
Check out these great programs to get started:
International Migratory Bird Day—International Migratory Bird Day is coming up soon. This day in mid-May celebrates the migration of nearly 350 species of migratory birds between nesting habitats in North America and non-breeding grounds in Latin America, Mexico, and the Caribbean. Of course Bird Day is not just a day; IMBD invites us to celebrate birds every day of the year!
Celebrate Urban Birds—We’re all close to birds, even in large cities like Cincinnati. Check out Celebrate Urban Birds for more on urban bird watching.
NestWatch—Have a nest in your yard or near your school? NestWatch, a program of the Cornell Lab of Ornithology, is a nationwide monitoring program designed to track nesting patterns of birds, including when nesting occurs, number of eggs laid, how many eggs hatch, and how many hatchlings survive. NestWatch is easy and is a great activity for families! Become a certified NestWatcher using the helpful tips on the organization’s site, and record your findings to help researchers and scientists gather essential information on reproductive biology of birds.
Ebird—With Ebird, you can submit your observations of birds anytime! This program, launched by Cornell Lab of Ornithology and National Audubon Society, allows you to create maps and lists of the birds you’ve seen, and share your observations with other birders. Your observations will join those from around the world and contribute to a better understanding of bird distribution across the western hemisphere.
Get ready for next winter:
Project FeederWatch—Cornell Lab of Ornithology organizes this winter-long survey of birds that visit feeders at backyards, and other areas across North America. FeederWatchers count the birds they see at their feeders, helping scientists track movements of bird populations.
Christmas Bird Count—The Audubon Society organizes the longest running Citizen Science survey in the world, which provides critical data on population trends.
What will you see in your backyard this Earth Week?

CREW continues to make progress in improving the success of artificial insemination (AI) for propagating endangered
cats. In recent research, we incorporated treatment with oral progesterone (Regumate) into our AI protocol for domestic cats to down-regulate ovarian function prior to ovarian stimulation. This approach allows us to control ovarian activity more precisely and conduct AI procedures on a fixed time schedule.
Our first attempt using this method in exotic felids involved our fishing cat named Ratana,who was incapable of breeding naturally after losing a front leg due to injury. Ratana was fed a small amount of oral progesterone daily for one month to suppress her ovarian activity and then treated with gonadotropins to induce follicular growth and ovulation. Laparoscopic AI of both oviducts with freshly collected sperm from our resident male, named Gorton, resulted in conception and the birth of a male fishing cat kitten after a 69 day gestation.
This kitten was the first non-domestic cat born following the use of oral progesterone for fixed time AI, and represents the fifth cat species (fishing cat, ocelot, Pallas’ cat, tiger, domestic cat) that we have produced with oviductal AI. This new approach could greatly advance our capacity to use AI for the genetic management of endangered felid species.

Last week, Sihil, the Zoo’s 14-year-old ambassador ocelot, showed off her spots at an Ocelot Conservation Day Festival held in Brownsville, Texas. The U.S. Fish and Wildlife Service (FWS), the Friends of Laguna Atascosa National Wildlife Refuge and the Gladys Porter Zoo hosted the event to highlight ocelots, which are native to South Texas.
In the United States, ocelots once roamed throughout Texas and into Arkansas and Louisiana. Today, fewer than 50 wild ocelots remain in the country, deep in South Texas. One of two known Texas populations survives on the Laguna Atascosa National Wildlife Refuge. Since 1997, the annual ocelot festival has helped educate thousands of people about the importance of conserving ocelots and what they can to do help. Nothing impacts the audience more than experiencing a real live ocelot, which is where Sihil comes in.
The Cincinnati Zoo’s Cat Ambassador Program is one of the few programs in the country that trains and works with ocelots to display natural behaviors for large audiences. Since 2007, Sihil and her trainers have traveled to Texas each year to appear at the festival. Having recently taken on a new role as the Education Advisor for the AZA’s Ocelot Species Survival Plan (SSP), I was fortunate to be able to tag along this year to learn more about Texas ocelot conservation and meet the people I’ll be working with on it in person.
After packing up the Cat Ambassador Program van with everything to meet Sihil’s needs for the week-long trip, which included a travel crate, her larger mobile “condo” crate, a cooler packed with raw meat and bones, plenty of kibble and enrichment items (aka toys) and more, we hit the road.
Sihil is a champion traveler. She slept a lot, which cats are known to do, so that I often forgot she was even there (despite the persistent ocelot scent that lingered in the van) until she let out a low, raspy meow to remind us when it was close to snack time. After two days of travel, we arrived at our cabin at Cactus Creek Ranch and prepared for the next two days’ events.
The first order of business was an appearance at the Cameron County Office in downtown Brownsville. FWS staff briefed the Cameron County employees on the issues facing ocelots in their area and talked about ways they could work together to solve them. For example, FWS and the Texas Department of Transportation are teaming up to install wildlife crossings on highways to prevent ocelot road mortality, one of the major problems they face. Next, it was Sihil’s turn to impress the audience, working with her trainer, Alicia Sampson, while Wendy Rice, the other trainer, shared information and answered questions.
Later that afternoon, the Friends of Laguna Atascosa National Wildlife Refuge hosted an Ocelot Soiree at the Gladys Porter Zoo to raise funds for conservation. The food, drinks, auction, presentations and conversation were fantastic, but Sihil once again stole the spotlight.
The following day was the actual Festival held at the Gladys Porter Zoo. More than 1,300 people attended the event and took part in a variety of activities from face painting and crafts to talking to wildlife officials about protecting ocelots and planting native plants to restore the thorn scrub habitat on which they rely.
There was even a singing zoologist, Lucas Miller, on hand to entertain families with his conservation-minded songs. He wrote an ocelot song just for the occasion:
And, of course, Sihil and her trainers took their turn on stage throughout the day. For many of the local families in the audience, this was their first time seeing a real live ocelot, an ambassador for her wild counterparts that live right there in South Texas. She got some great local press.
Sihil did great. The trainers never force her to perform; it’s her choice whether she wants to come out on the table and display the behaviors Alicia asks her to do through visual and verbal cues. In return, she is rewarded with meaty treats. Sihil and Alicia have developed a special trust and bond over the past 10 years that they’ve worked together. Alicia can read Sihil’s body language and pick up on cues such as the “naughty tail” – when Sihil begins quickly flicking the tip of her tail back and forth – that let her know when it’s time to wrap it up.
And what did I do while they were working? Took lots of pictures, talked to lots of people and wrote down lots of notes. As the Ocelot SSP Education Advisor, I will play a role in helping to develop and implement an education and awareness campaign to accompany one of the next big goals – the translocation of ocelots into the area. Although there are still a lot of logistics to work out, the hope is that ocelots from a healthy population in Mexico will bring much needed new genetic material into the small population in South Texas in the near future. When a population starts to lose genetic diversity, it is less able to adapt to its environment and more likely to go extinct. The animals are more prone to diseases, low reproductive rates and genetic abnormalities.
In the meantime, Sihil will continue to educate Cincinnati Zoo visitors this summer during the Cat Ambassador Program’s Cheetah Encounter show. At 14 years old, Sihil is still in tip-top shape, but approaching the expected lifespan of about 20 years in captivity. So the Zoo has brought in a new young male named Santos as her protege. Maybe next year, Santos will carry on Sihil’s legacy at the Ocelot Conservation Festival.
