Lincoln Park Zoo welcomes rare pregnancy of critically endangered rhino

Lincoln Park Zoo has thrilled animal enthusiasts by announcing the pregnancy of Kapuki, a critically endangered eastern black rhinoceros. The revelation coincided with the zoo's celebration of World Rhino Day in late September, marking a significant occasion in the conservation community.

This exciting news involves Kapuki, a 20-year-old rhino, who is expected to give birth in early spring 2026. The baby will be her third calf, but the first with 21-year-old Utenzi, the zoo said. According to the announcement, the pregnancy was confirmed through hormone analysis of noninvasively collected fecal samples, a testament to the innovative approaches in wildlife monitoring.

Significance and conservation efforts

Kapuki's pregnancy plays a crucial role in the efforts to conserve the critically endangered eastern black rhinoceros, a species that the zoo says has faced a dramatic population decline of 98% from 1960 to 1995 due to poaching. According to Curator Cassy Kutilek, "Every birth matters to this critically endangered species, and we’re proud to play a role in growing the eastern black rhinoceros population." As reported by the press release, Lincoln Park Zoo's participation in the Species Survival Plan (SSP) highlights its commitment to collaborative conservation initiatives among AZA institutions.

Life at Lincoln Park Zoo

Currently, Lincoln Park Zoo houses three rhinos, and the addition of the new calf will raise the tally to four within the Regenstein African Journey exhibit. Newborn rhinos can stand within hours of birth but depend on their mothers for nourishment for up to two years, the zoo detailed in its press release. Additionally, adult eastern black rhinos, known for their significant size, can weigh as much as 3,000 pounds and measure up to 12 feet.

In support of these efforts, zoo patrons are invited to celebrate this rhino pregnancy with contributions through the zoo's Wish List or by participating in the Adopt an Animal program. These initiatives channel funding towards daily care needs like fresh leafy plants, ensuring the sustenance of the precious rhino population.
