Arnieta, a 5-year-old reticulated giraffe at Brookfield Zoo, gave birth to a male calf in the early afternoon on November 12. Mother and baby spent their first week together off exhibit to allow for good maternal bonding and to make sure the calf is developing normally.
The birth took place in an off-exhibit area. Soon after the birth, the
140-pound, 6-foot-2-inch-tall calf stood and began nursing. This week they are
being introduced to the other females in the herd: Mithra, 22; Franny, 21; and
Jasiri, 7, in the zoo’s Habitat Africa! exhibit.
This calf is the 58th giraffe born at Brookfield Zoo. His birth marks three
generations of giraffes at Brookfield Zoo, as Franny is Arnieta’s mom. The
sire, Hasani, 4, who arrived at Brookfield Zoo in 2010, is on a breeding loan
from Lee Richardson Zoo in Garden City, Kansas. The calf’s birth is a very
important addition to the North American zoo population because it is the first
offspring for both Arnieta and Hasani. The pairing of the two was based on a
recommendation from the Association of Zoos and Aquariums’ Reticulated Giraffe
Species Survival Plan (SSP). An SSP is a cooperative population management and
conservation program for select species in accredited AZA zoos and aquariums.
Each SSP manages the breeding of a species to maintain a healthy and
self-sustaining population that is both genetically diverse and demographically
Following a 14½-month gestation period, mother giraffes give birth while standing, resulting in an approximately five-foot drop delivery for the calf. Within an hour after birth, the calf born at Brookfield Zoo was standing. When fully grown, he could potentially reach 18 feet tall.
Giraffe numbers have declined by 40 percent in the last decade, and there are now fewer than 80,000 individuals in Africa. There are fewer than 5,000 reticulated giraffe left in East Africa.
Additionally, of the nine subspecies of giraffes in Africa, two—the West African giraffe and the Rothschild’s giraffe—are classified as endangered, with less than 250 and 670 individuals, respectively, remaining in the wild. The populations are declining due to a number of factors, including habitat loss and fragmentation coupled with human population growth and illegal hunting.
