Giraffe calf born on June 21, 2013, with herd at Brookfield Zoo
Jasiri, a 7½-year-old giraffe at Brookfield Zoo, gave birth to a male calf on June 21. The first-time mom gave birth outside in an off-exhibit area. Soon after being born, the 173-pound, 5-foot-9-inch-tall calf stood and was nursing not long after that.

This calf is the 59th giraffe born at Brookfield Zoo. The sire, Hasani, 4, arrived at Brookfield Zoo in 2010, and is on a breeding loan from Lee Richardson Zoo in Garden City, Kansas. He is also the father of Dave, a nearly 8-month-old calf born in November 2012.

In addition to Dave and Hasani, other members of Brookfield Zoo’s giraffe herd that can be seen on exhibit with Jasiri and her calf are Mithra, 22; Franny, 21; and Arnieta, 5.

Following a 14½-month gestation period, mother giraffes give birth while standing. When fully grown, the new calf 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.

The zoo has been experiencing a baby boom this year. In addition to this giraffe calf and the one born in November 2012, two sloth bear cubs were born on January 20, a klipspringer was born on June 14, two addax antelopes were born on June 7 and 22 and two more are expected, an Angolan colobus monkey was born on March 9, and three dolphins are expecting.
