Rare twins have been born to a Maasai giraffe in Nairobi's National Park, the Kenyan wildlife minister announced on Tuesday.
"This is an extremely rare occurence," Najib Balala said on Twitter in a post accompanied by a picture of the mother watching over her twin offspring.
Only about 117,000 giraffes remain in the wild, according to the Giraffe Conservation Foundation. It said numbers of the gentle long-necked beasts in Africa have plummeted by 30 percent over the last 30 years, describing it as a "silent extinction".
Kenya is home to three subspecies of giraffe, the Maasai, the reticulated and the Rothschild.
Nairobi National Park lies just seven kilometres from the heart of the Kenyan capital, and is a tourist magnet for its wildlife including lions, leopards, rhinos and buffalo which graze against a backdrop of distant skyscrapers.
At 15 months, giraffes have one of the longest gestation periods for mammals. They give birth standing up, which means their calves drop just under two metres to the ground.
This startling introduction to life gets them up and running around in less than an hour. A newborn calf is taller than the average adult human.
Only a handful of twin births have been documented worldwide, with most twins not surviving.
In the wild, giraffes can live up to 25 years, while in captivity they survive on average for more than 35 years.
