The Short Happy Life of a Serengeti Lion
National Geographic — David Quammen & Michael Nichols
The story of C-Boy, Hildur, the Vumbi pride and the Killers.
Fate unknown
Also known as Ziggy · The Golden-Maned Partner
c. 2004 – unknown
Born in Serengeti National Park, Tanzania
Hildur was a golden-maned male lion of Tanzania’s Serengeti National Park and the only coalition partner of C-Boy. Guides knew the pair as Bob and Ziggy. Together they were followed for two years by National Geographic writer David Quammen and photographer Michael “Nick” Nichols, and their story appeared in the magazine in August 2013.
Quammen described Hildur as handsome and always eager to mate, but far less keen to fight. When three males of the Killers coalition attacked C-Boy in 2009, Hildur was seen running away, leaving C-Boy to face them almost alone. Yet the bond between the two endured: they moved east together, took over the Vumbi and Simba East prides, and in the rain were photographed licking the water from each other’s fur.
Hildur became famous for his long runs across the plains. Nichols photographed him running about five miles to reach his other pride after it had made a kill. When C-Boy died in June 2018, Hildur, also around 14, was still alive. What happened to him after that has not been documented.
An Old Norse name meaning battle, used by the Serengeti Lion Project. Who chose it has not been documented; ironically, Hildur was known more for mating than for fighting.
Paired with C-Boy’s nickname, Bob. Ziggy is also the name of Bob Marley’s eldest son; whether guides chose it for that reason has not been documented.
Born in Serengeti National Park, Tanzania.
Resident male, with C-Boy, of the small Jua Kali pride near the source of the Seronera river.
When the Killers attacked C-Boy, Hildur was seen fleeing. The pair lost the Jua Kali pride and moved east together.
Took over the Vumbi pride at the Zebra Kopjes and the Simba East pride with C-Boy.
Photographed by Nick Nichols running about five miles across the plains to reach his other pride after a kill.
Featured in National Geographic’s “The Short Happy Life of a Serengeti Lion”. A photo of Hildur and C-Boy in the rain, “Sharing a shower”, was shown in Wildlife Photographer of the Year.
C-Boy died. Hildur, around 14, was still alive.
No published record of his later life or death.
National Geographic described Hildur as a male who showed great eagerness to mate but little to fight, and he fled when the Killers attacked C-Boy. Even so, the two stayed together for the rest of C-Boy’s life.
Like C-Boy, Hildur lived well beyond the 12 years usually seen as the limit for a wild male lion in the Serengeti.
