Hannah Shirley Celebrates 52nd Birthday With “Hungry Hungry Hippos” Party
San Diego Humane Society’s Ramona Wildlife Center celebrated a remarkable milestone today as Hannah Shirley, the world’s oldest living pygmy hippopotamus in managed care, turned 52 years old.
To mark the occasion, Hannah enjoyed a festive “Hungry Hungry Hippos”–themed party complete with floating fruit treats and colorful decorations inspired by the beloved children’s game. San Diego Humane Society’s Project Wildlife team, who have cared for Hannah since her rescue in 2002, joined in the celebration alongside guests and supporters.
“Every day with Hannah Shirley is a gift,” said Autumn Welch, Wildlife Operations Manager at San Diego Humane Society. “Her playful spirit and resilience continue to amaze us. Seeing her celebrate 52 years with such energy and curiosity is nothing short of extraordinary.”
Born on Nov. 22, 1973, Hannah surpassed the previous longevity record earlier this year, officially becoming the oldest pygmy hippo ever in managed care worldwide. The species typically lives 25 to 30 years in the wild.
Hannah was rescued from a private backyard in Escondido in 2002 and has since thrived in a 13,000-square-foot habitat complete with a pond and pool. Her days are filled with spa-like back rubs, sprinkler showers and carefully prepared meals that support her advanced age.
“Anyone who meets Hannah falls in love with her,” said Angela Hernandez-Cusick, Wildlife Rehabilitation Supervisor at San Diego Humane Society. “She embodies the joy and connection that make caring for wildlife so rewarding.”
Hannah’s care is managed by San Diego Humane Society’s Project Wildlife team, whose dedication ensures her continued comfort and well-being. As one of only a few dozen pygmy hippos in managed care across North America, Hannah remains a cherished ambassador for her vulnerable species — and a symbol of the extraordinary impact of compassionate, expert care.
