Zurich, Switzerland – The Lewa Savannah at Zurich Zoo has a new resident. Obi, an eight-year-old male reticulated giraffe, arrived from Schönbrunn Zoo in Vienna at the end of August and has been gradually acclimatizing to his new home since late September.

Standing tall above the female giraffes, Obi immediately drew attention with his size and the numerous bumps on his head, known as exostoses, which protect him during male-to-male fights for mates. Zoo Director Severin Dressen expressed delight at the long-awaited arrival, saying, “Now it’s happened, the bull is here, and we’re delighted that we can now hopefully successfully participate in the breeding of the critically endangered reticulated giraffes.”

Obi’s introduction is a crucial step in the European Endangered Species Breeding Programme (EEP). Reticulated giraffes are critically endangered, with populations having declined by at least 30 percent over the past 35 years. Breeding in captivity ensures a stable reserve population and supports species-appropriate care, helping preserve the species against “silent extinction.”

Obi will breed with three remaining females, while his half-sister Jahi will soon leave the zoo to prevent inbreeding. Gradual contact with other savannah species, including zebras, rhinos, and impalas, is planned to foster natural social dynamics and integration within the enclosure.

The Lewa Savannah replicates the giraffes’ natural habitat with ample space, vegetation, and safe areas for exploration. This careful acclimatization ensures the animals thrive physically and socially, supporting both conservation and welfare goals. Obi’s arrival marks a vital chapter in Zurich Zoo’s ongoing efforts to protect the reticulated giraffe both in Europe and in its native habitat in Kenya.
