The GSC Announces – Holly the Hippo is Pregnant

GREENSBORO, NC – Revolution Ridge, the Greensboro Science Center’s largest expansion to-date, opened in June of 2021 to record crowds. The 12-acre, 10-exhibit expansion was designed to be a breeding center for unique and endangered wildlife from all over the world. The signature pygmy hippo exhibit was specifically designed (at over $1.4M) to mimic key features of their wild habitat, including: three deep wading pools, a waterfall, a shallow river, a sandy beach, a mud wallow, both sun and shade areas, a temperature controlled indoor pool and safe areas for bedding and birthing. After less than two years in Greensboro housed with her mate Ralph the hippo, ultrasound imaging of Holly shows what appears to be an active and healthy hippo calf with an estimated due date range between March 15 and May 1, 2023.

Glenn Dobrogosz, the GSC’s CEO says, “While the GSC team is clearly very excited, we have to be cognizant that Holly is a first-time mom and successful reproduction in a wide array of species comes with many challenges. Survival rates can vary with age, experience, genetics and unknown health conditions. So far, the health and activity level of the calf in-utero looks positive.”

Pygmy hippos are listed as an endangered species and can only be found in four West African countries. Their demise in the wild is directly linked to habitat loss, river pollution and being hunted for local food sources.

The GSC would like to thank the Morrisette Family for sponsoring the pygmy hippo exhibit.
