Zoo Babies

Our 7-year-old female Swann gave birth to Cobb, a male calf at 12:35pm on Nov. 6. Mom and baby are both doing great.

Addras are the largest and most endangered of all gazelle species, which makes this birth even more special. The calf weighed slightly more than 11 pounds at birth.

This is the third calf for both Swann and father Kamal.

During the cold winter months, they will remain in their cozy indoor facility with the rest of the Zoo’s herd. When the weather warms up in the spring, guests will be able to see the newcomer in the giraffe yard in Plains.

Native to the arid Sahara Desert regions in northern Africa, Addra gazelle mothers give birth to a single calf at a time. To avoid predators, the newborn will spend several weeks hiding among the tall, dry grasses and their light tan coat provides the perfect camouflage. As they grow older, the youngster’s coat will grow out with more white along his neck and back.

JoJo is an incredible, experienced mom, and this is her sixth calf.

The baby’s name is Binti, which means “daughter” in Swahili. She is nursing well and has already started following mom and the other members of our kudu herd into the small yard next to their barn in Plains.

Greater kudus are native to eastern and southern Africa. These woodland antelopes can weigh up to 600 pounds, however females are noticeably smaller than males. Our new cutie weighed a healthy 33 pounds at birth.

Against the arid landscape of the African savannah, the kudu’s tan coat marked with thin, white stripes offers great camouflage to protect against predators.

In the wild, female kudus will form groups of mothers and calves. Moms will give birth in areas of tall grass that provide the babies with protection from predators, which is especially important during the first few weeks. During that time, kudu mothers spend most of their time grazing and only tend to the calves for short periods to nurse. When the calf is a little older, mom returns and the two spend the next several months together bonding.

When she hatched in February, the tiny female tortoise weighed just half an ounce — about the size of a single AA lithium battery. The fragile hatchling will remain behind the scenes in Deserts until she grows a little larger.

The first of her species ever hatched here at the Indianapolis Zoo, this birth is also a victory for the conservation of this beautiful species, as spider tortoises are critically endangered in the wild in Madagascar.

When a spider tortoise egg is laid in the wild, it goes through a unique period of suspended development called diapause. By remaining inactive during the coldest part of the year, the egg can then grow when the weather warms up, allowing the baby tortoise to hatch during peak environmental conditions. After our egg was laid in October 2020, Zookeepers replicated that process by carefully lowering the temperature and closely monitoring the egg for four weeks to kickstart development. From there, the egg was incubated at 88 degrees for 120 days until our hatchling emerged from her shell.

Long-tailed macaque Glenda gave birth on New Year’s Day, then macaque Kathy added another baby to our troop on Jan. 3. Both mothers and their infants are doing great. Genevieve is the first baby for 6-year-old Glenda, and Cora is the second for 7-year-old Kathy. Her other offspring, Chi, is still part of our troop as well.

10-year-old Momba also gave birth to her third infant on Nov. 17, 2020. The female, named Juniper, is nursing well and already growing.

Following a pregnancy of about 5 ½ to 6 months, female long-tailed macaques give birth to a single baby. Weighing less than a pound, the newborn will cling tightly to its mother’s stomach as she travels. Momba is an experienced and attentive mother, and keeps her infant close. Her two other offspring, Cynde and Java, are also still part of the troop.

Like all newborn macaques, our baby has a bare face with black hair that will lighten to gray beginning around 3 months old.

We’re also celebrating a first for our Zoo — one of our newcomers was born to a same-sex pair.

Same-sex pairings have also occurred with penguin species in the wild and in other zoos. Our two male birds became first-time dads when their chick hatched on Dec. 15. A female that’s actually paired with another penguin laid the egg and left it with the male couple, who have been caring for it ever since. Gentoo penguins co-parent their young, and just as a female-male pair would do, the two fathers have taken turns tending the nest, incubating the egg and now feeding the chick.

The first of our three chick hatched a week earlier on Dec. 8 and the other hatched on Dec. 27, both to female-male pairs who are also first-time parents. All the adults are doing a great job as caregivers, and while we don’t know the gender of the chicks, the young birds are both growing quickly. The first-born chick weighed 99.7 grams at birth and has grown to 2,000 grams (4 pounds, 6 ounces) at its most recent weigh in. The second chick has already grown to 1,405 grams (3 pounds, 1 ounce) from its birth weight of 114 grams.

These are the first penguin chicks hatched here since 2012, and the first for our Gentoo flock since 2011.

Even the smallest animals born here at the Zoo give us a big thrill!

Our Oceans family welcomed the birth of a tiny female cownose ray on Nov. 11. Zookeepers named the pup Squiggy, because her tail was so squiggly from being curled up before birth.

Female cownose rays will carry their pups for 12 months before giving birth, and all three of our babies were born to different females.

When rays are born, their wings folded tightly over their bodies almost like a taco. They quickly unfurl their fins and learn to glide. At birth, the babies each weighed between 3-4 pounds, and they remain small for a while, making it easy for guests to pick out our youngster from the rest of the rays swimming with the school in our Oceans touch pool.

Cownose rays are a near-threatened species, which makes these births even more special.
