Houston Zoo plans to relocate Kirby, her mother Shanti and older sister Joy together as part of a national conservation effort. The zoo has not announced when the elephants will leave or where they will go.
According to Chron, the zoo confirmed the trio will remain together at their new home, but has not disclosed a destination or moving date. The transfer is part of the Association of Zoos and Aquariums' Species Survival Plan, which the zoo says supports genetic diversity and the long-term health of Asian elephants in human care. The AZA's Asian Elephant Species Survival Plan is part of the association's broader coordinated population-planning effort, according to a program update from the Association of Zoos and Aquariums.
What the transfer plan does—and what remains unknown
The zoo has confirmed that Kirby, Shanti and Joy will stay together, but has not announced their destination or departure date. The AZA's Species Survival Plan is part of coordinated population planning, not a public timetable for this family's move.
The AZA's SAFE Asian Elephant Program Plan 2024-2026 says its 2023 analysis counted 137 Asian elephants at 33 institutions, including 32 AZA-accredited facilities and one AZA Approved Sustainability Partner. That count is distinct from the plan's estimated wild Asian elephant population of 41,410 to 52,345.
Kirby was born on November 15, 2024, and weighed 314 pounds, according to the Houston Zoo's birth announcement. The zoo named her after Kirby Drive. She also appeared on Good Morning America before she turned two, according to Chron.
A Mother With Deep Roots in the Herd
Shanti, now 36, has given birth to seven calves in Houston, according to Chron. She is also the mother of Nelson, born in May 2020, who will not join Kirby, Joy and Shanti in this relocation. The zoo has separately announced plans to relocate Nelson and another male elephant, Tucker, under the same conservation program.
Joy contracted elephant endotheliotropic herpesvirus, or EEHV, before her second birthday. The virus can be fatal to young elephants. She survived after intensive care that included antiviral medication and blood transfusions, with herdmate Methai donating more than 17 units of blood, according to Chron.
Houston's Herpesvirus Research Reaches Across the Country
Joy's survival wasn't just a personal triumph for her family — it fed directly into a research program that has reshaped elephant medicine nationwide. Houston Zoo and Baylor College of Medicine developed treatment protocols that have since helped guide care for infected elephant calves at other zoos, the Chron report states. That partnership traces back to 2009, when it was established after Mac, a two-year-old Asian elephant calf, died suddenly from the virus in 2008, according to the Houston Chronicle. Mac's death set off more than 15 years of diagnostic advancement and vaccine development.
That work led to a historic milestone in June 2024, when Houston Zoo's 40-year-old elephant Tess became the first elephant in the world to receive an experimental mRNA vaccine targeting the deadly EEHV1A strain, as The Guardian reported at the time. Tess is the mother and grandmother of several elephants in the Houston herd. Hoodline previously covered Tess's vaccine milestone when it happened.
By July 2026, researchers from Baylor College of Medicine and Houston Zoo had published two companion peer-reviewed papers in the Journal of Virology presenting the first clinical evidence that the experimental vaccine can protect young Asian elephants from severe EEHV1A disease, per the Houston Zoo. EEHV remains the leading cause of mortality among juvenile Asian elephants in North American care, which underscores why that evidence mattered so much to zoos nationwide.
Protocols Now Protecting Calves Nationwide
The real-world payoff showed up at other institutions. In mid-2025, two vaccinated juvenile elephants at the Cincinnati Zoo, named Sanjay and Kabir, successfully cleared active EEHV infections after receiving the Houston-developed vaccine, the Houston Chronicle reported, with the zoo confirming the calves tested negative after previously testing positive. More recently, on September 30, the Saint Louis Zoo administered a third dose of the Baylor/Houston Zoo-developed vaccine to an elephant named Jet, according to Focal Points. Oregon Zoo also recently gave its own calf, Tula-Tu, the Houston-developed shot, a story Hoodline covered in August.
Life at the McNair Habitat, For Now
Until the move happens, Kirby, Shanti and Joy remain at Houston Zoo's McNair Asian Elephant Habitat, which the zoo describes as featuring two outdoor spaces spanning more than 1.5 acres, a 7,000-square-foot elephant barn, and pools holding 160,000 and 80,000 gallons. The zoo has invited visitors to come see the family together before they depart. The habitat's scale reflects years of expansion, including a barn built for bull elephants. In 2024, bull elephant Chuck arrived from the Denver Zoo in a swap that sent 14-year-old bull Baylor to Colorado, a move previously detailed by KHOU.
The stakes behind these coordinated transfers extend well beyond any single zoo. Wild Asian elephant populations are estimated at just 40,000 to 50,000 individuals across 13 range countries in South and Southeast Asia, remaining classified as Endangered due to severe habitat loss and human-elephant conflict, according to the U.S. Fish and Wildlife Service. The AZA plan says wild populations have declined by nearly 50% over the last three generations, which is precisely the kind of pressure that makes managed breeding and genetic planning among accredited zoos so urgent for the species' long-term survival.
For now, Houston Zoo has not said where Kirby, Shanti and Joy are headed or when they'll leave, and it remains unclear how the zoo will reorganize its remaining elephant herd within the McNair habitat once the trio departs.
