Extremely Rare Female White Giraffe and her only Calf Slaughtered by Poachers in Eastern Kenya

Two rare white giraffes, a female, and her calf were killed by poachers in Kenya, officials have said, illustrating the challenges of wildlife conservation and the persistent and devastating impact of poaching in the East African nation.

The deaths of the giraffes left just one of the unusually colored animals in the country’s wild, a bull, out of a family of three, conservancy officials said.

Officials with the Ishaqbini Hirola Community Conservancy in Garissa County, northeastern Kenya, where the giraffes lived, said on Tuesday in a Facebook post that armed poachers had killed the two animals in the town of Ijara Town.

Conservationists found the skeletal remains of the giraffes, and it was estimated from the state of the carcasses that the animals had been killed four months ago. The Kenya Wildlife Service said it was investigating the killings.

“This is a very sad day for the community of Ijara and Kenya as a whole,” the manager of Ishaqbini Hirola, Mohammed Ahmednoor, said in a statement. “We are the only community in the world who are custodians of the white giraffe.”

“Its killing is a blow to the tremendous steps taken by the community to conserve rare and unique species, and a wake-up call for continued support to conservation efforts,” he added.

With their unique white hide, the female giraffe and her calf drew global attention when they were sighted grazing in 2017 by a villager in Kenya who was herding his animals near the Ishaqbini sanctuary, which is also home to the critically endangered hirola antelope. Last year, a second calf was born, bringing the total number of white giraffes in the area to three.

The giraffes did not have albinism, in which melanin is absent, but displayed the symptoms of a different genetic condition, known as leucism, in which animals often experience a partial loss of pigmentation. Ishaqbini said the female white giraffe had dark pigment in her soft tissue, noting that, “Her eyes were dark in color.”

The Giraffe Conservation Foundation estimates that the number of reticulated giraffes in the world, which includes the species found in Ishaqbini and across north and northeastern Kenya, has declined by more than 50 percent in the past three decades, to 15,780 in 2018.

While conservation efforts in Kenya have improved, the country has for decades struggled to contain the threat to its wildlife population, a source of much-needed tourism revenue. This is especially true of its elephant and rhino populations, whose ivory and horns are valued as status symbols and used as ingredients in traditional medicine.

Mr. Ahmednoor, the manager of Ishaqbini, lamented the likely impact of the white giraffes’ killing, saying that the animals were “a big boost to tourism in the area.”

Also, he added, “This is a long-term loss given that genetics studies and research which were significant investment into the area by researchers has now gone down the drain.”

Beyond Kenya, a white giraffe was also spotted in 2016 in Tanzania, at the Tarangire National Park.
