Shani, a six-year-old Masai Giraffe at the Sacramento Zoo, gave birth to a healthy 163-pound male calf on April 10.
The calf has been given the name Rocket. Zookeepers chose the name based on his playful personality and "on-the-go" attitude.
Currently, mother and son spend most of their time behind-the-scenes in the barn, bonding, with periodic exercise sessions in the side-yard. Rocket is also becoming acquainted with his herd-mates, or “tower”, as they stick their head over fences or stall doors to inspect him. The calf is also learning to manipulate browse with his long, prehensile tongue, even though nursing is his still his main source of nourishment.
Based on the signs Rocket, Shani, and the rest of the herd are giving, zookeepers anticipate the pair making their public exhibit debut in mid-May. However much like other timelines at the Zoo, staff members confess that everything will be done on mom and the calf’s terms.
In the meantime, Rocket and Shani will have intermittent access to the giraffe barn’s side-yard, where lucky and quiet guests might catch a glimpse of Rocket. Staff report that these viewing areas will continue to remain quiet zones, creating a peaceful environment for the pair until the time that they venture out into the main exhibit.

The Sacramento Zoo is now home to six giraffes: three female Reticulated Giraffes, one male Masai Giraffe (Chifu, the father of the new calf), one female Masai Giraffe (Shani, the mother), and the calf. In 2010, the Zoo completed renovations on the giraffe exhibit that includes a state-of-the-art, heated barn. This is the 19th calf born at the Sacramento Zoo, going back to 1964 when the species was first housed here.
The Giraffe (Giraffa camelopardalis) is divided into nine subspecies. There are three subspecies most commonly found in zoological facilities: Reticulated, Rothschild, and Masai.
The Masai Giraffe (Giraffa camelopardalis tippelskirchi), also known as the Kilimanjaro Giraffe, is the largest subspecies and tallest land mammal. It is native to Kenya and Tanzania.
In addition to a difference in size, Reticulated and Masai Giraffes have slightly different spot patterns; a Masai Giraffe's spots are usually darker and irregular in shape.
Gestation is 14 to 15 months with the female giving birth alone in a secluded spot away from predators. When a calf is born, it can be as tall as six feet and weigh 150 pounds. Within minutes, the baby is able to stand on its own.
According to the Giraffe Conservation Foundation, the Masai may be the most populous of the Giraffe subspecies. There is an estimated fewer than 37,000 remaining in the wild, (though recent reports of significant poaching would suggest it likely to be significantly less) and approximately 100 individuals kept in zoos.
Habitat loss, poaching, disease and civil unrest pose the most significant threats to wild giraffe.
The Sacramento Zoo is one of 32 facilities managing 120 Masai Giraffes in the Association of Zoos and Aquariums (AZA) population. The Sacramento Zoo is a partner with the Wild Nature Institute (a field research group that is currently studying Masai Giraffe demographics and the African Savanna ecosystem with photo recognition software). Observation of giraffes in zoos is helping field researchers to recognize physical characteristics and social behaviors that they are seeing in the wild. The study, which includes more than 1,500 Masai Giraffes, will allow researchers to follow the giraffes’ movements and reproduction habits in the wild in order to understand where and why their populations are declining.
