Lincoln Park Zoo Says They Are ‘Hooked’ on New Sloth

1

Lincoln Park Zoo, in Chicago, Illinois, has announced a new arrival. A Hoffmann’s Two-Toed Sloth was born on July 25, at the zoo’s Regenstein Small Mammal-Reptile House!  

The sloth infant joins its 21-year-old mother, Hersey, and 32-year-old father, Carlos, on exhibit at the zoo. The sex and measurements of the newborn are yet to be determined, as the baby is clinging tight to Hersey. The sloth baby is a part of the Hoffmann’s Two-Toed Sloth Species Survival Plan, which cooperatively manages the accredited zoo population. The baby sloth is the first offspring of this breeding pair.

“The sloth infant appears healthy and is passing critical milestones such as nursing regularly and clinging well to mother,” said Curator Diane Mulkerin. “Hersey is a first-time mother and is being very attentive to her new young.”

The sloth infant, Hersey, and Carlos can be seen on exhibit daily at Lincoln Park Zoo’s Regenstein Small Mammal Reptile House from 10 a.m. – 5 p.m. Sloths are nocturnal so the infant and mother can be seen curled up in the canopy throughout the day and are more active towards the evening.

Hoffmann’s Two-Toed Sloth (Choloepus hoffmanni) is a species of sloth from Central and South America. It is a solitary, largely nocturnal and arboreal animal, found in mature and secondary rainforests and deciduous forests. The common name commemorates the German naturalist, Karl Hoffmann.

The species is often confused with its relation, the Linnaeus’s Two-Toed Sloth, which it closely resembles. The primary difference between the two species relate to subtle skeletal features; for example, Hoffmann’s Two-Toed Sloth has three foramina in the upper forward part of the interpterygoid space, rather than just two, and often has fewer cervical vertebrae.

Hoffmann’s Two-Toed Sloths have large hooked claws that help the species hang from treetops in the canopies of tropical rainforests. On average, these sloths weigh around 12 pounds and can reach 27 inches in length and spend nearly all of their time upside down in treetops.

Meet the New Rookie Chicago Cubs

Kovler Lion House, at Lincoln Park Zoo, is home to an important pair of siblings. Born June 26, the Red Panda cubs are the first of their kind born at Lincoln Park Zoo. The male and female are the offspring of first-time dad, Phoenix, and experienced mom, Leafa.

The endangered duo currently isn’t visible to the public, nor will they be for some time. Instead, they’re cuddled up in a behind-the-scenes den with mom Leafa, as is typical for the species. They can remain in this cozy space for up to three months, with mom periodically leaving to feed or tend to other needs.

Thanks to a special camera in the den, though, staff can keep an eye on the tiny new arrivals. Red Panda cubs weigh 4-5 ounces at birth and are fully furred, although their coat is yellow as opposed to the bright red of adults. The little ones’ eyes are closed for the first 18 days of life, meaning they’re totally dependent on mom in the crucial early weeks.

The tiny Red Pandas were recently given names in honor of their hometown, Chicago. Wrigley Field, home of the Chicago Cubs baseball franchise, is located at the iconic intersection of the streets Clark and Addison. It seemed fitting to name Chicago's other cubs (Red Panda- that is) in honor of the legendary American team. Lincoln Park Zoo's new male cub has been named Clark, and his sister is now known as Addison.

Sharon Zackfia, a committed supporter of Chicago’s free zoo, selected the city-centric names. “As a longtime lover of Red Pandas, I could not be more excited to have the honor of naming Lincoln Park Zoo’s first-ever Red Panda cubs,” she notes. “I am so proud to be a supporter of an institution that has brought so much joy and knowledge to the families of Chicago.”

The cubs themselves continue to do well in their behind-the-scenes den. Curator of Mammals, Mark Kamhout, reports that Clark and Addison are receiving great care from mom Leafa and continuing to hit new milestones. “Their eyes are open now, which is a big development for Red Panda cubs, and it looks like they’ve doubled in size since their physical last week.”

The baby, named ‘Bella’, is staying tucked close to her mother and appears to be doing well. Gorilla mom, ‘Bahati’, age 27, is experiencing motherhood for the third time. Her last pregnancy occurred in 2004, and her two adult offspring now reside in other Association of Zoos and Aquariums (AZA) accredited zoos. ‘Kwan’, age 25, the new infant’s father, and silverback of the family group, continues to keep a watchful eye on mom and baby.

“As with any birth, we are cautiously optimistic about the latest arrival. Bahati is an experienced mother whose maternal instincts are what we would hope to see with a newborn gorilla,” said Maureen Leahy, Curator of Primates.

The new baby joins a troop of six individuals, including two-year-old half-sisters ‘Nayembi’ and ‘Patty’ who were born at Lincoln Park Zoo in fall 2012.

“It’s really amazing to see this family group grow and adapt,” said Leahy. “Between the family group and bachelor troop, the gorillas at Regenstein Center for African Apes are a great representation of the species from newborn baby to fully mature silverback and several stages in-between.”

Kwan and Bahati were recommended to breed as a part of the Western Lowland Gorilla Species Survival Plan (SSP).

Eleven Ornate Box Turtles hatched at Lincoln Park Zoo, in Chicago, this week! The hatchlings are part of an effort to restore the native populations of turtles to their natural sand prairie habitat in Western Illinois, where they will return next summer. The hatchlings come from three different clutches provided by the U.S. Fish & Wildlife Service (USFWS).

“Every single hatchling is a success for the population,” said Diane Mulkerin, Lincoln Park Zoo curator. “Each animal represents being one step closer to restoring the natural grasslands and prairies in Illinois, which is necessary for the ecosystem to flourish.”

The turtles will remain at the zoo for the next several months where they can thrive without the threat of predation or disease. Once the animals grow both in size and strength, they will be re-introduced into grasslands and sand prairies protected by the Upper Mississippi National Wildlife and Fish Refuge in Savannah, Ill.

Lincoln Park Zoo participates in re-introduction programs for Smooth Green Snakes, Meadow-Jumping Mice in Illinois as well as Red Wolves, Trumpeter Swans, Guam Rails and other threatened and endangered species across the U.S.

Keepers Raise Tiny Antelope at Lincoln Park Zoo

1 klipspringer

There's a new baby Klipspringer at Lincoln Park Zoo in Chicago! Klipspingers (Afrikaans for 'rock jumper') are dwarf antelopes so tiny that an adult can fit all four of their hooves on a Canadian dollar coin, approximately 36 mm in diameter.

Born March 30, the female Klipspringer calf is the second offspring of mom Triumph and dad Dash, who were recommended as a breeding pair as a part of the Klipspringer Species Survival Program. The female calf joins her sister Arya, who also resides at the zoo.

See video of the baby Klipspringer:

 

“The Klipspringer calf is healthy and eating well and, as a result, has almost doubled her weight since birth,” said Curator of Mammals Mark Kamhout. “Currently, the calf is being hand-reared by our animal care staff after the mother was unable to provide adequate care.”

According to Kamhout, there are many factors that go into the decision to hand-rear an animal including medical condition, maternal care and proper habitat. After observation, the zoo’s animal care staff decided hand-rearing the calf was in the best interest of the animal.

“The calf will continue to receive around-the-clock care behind-the-scenes until she is able to fully navigate the vertical elements of her new habitat in Regenstein African Journey,” said Kamhout.

Lincoln Park Zoo Hand-raises a Wee Klipspringer

1 klipspringer

A Klipspringer —a tiny antelope native to Central and Eastern Africa—was born in early August at Lincoln Park Zoo in Illinois. Unfortunately, the baby’s mother didn’t display proper maternal care, and so the little one had to be removed to be hand-reared.  Animal care staff have done an excellent job nurturing the baby and it continues to grow behind-the-scenes at the zoo. Even at full size, the dwarf antelope will only measure 20 inches (51 cm) in height and weigh about 24 pounds (11 kg).

This common antelope species prefers rocky habitats, such as mountains and river gorges.  Klipspringers' hooves have a rubbery texture in the center that helps them grip rock, and the tough, sharp outer edges keep them firmly planted. They eat grasses, leaves, buds and fruits.

Klipspringers typically live in small family groups composed of a breeding pair and their young offspring. They are territorial, marking their territories with small scent-producing glands located on the face. Males can use their pointy, four-inch-long (10 cm) horns to wrestle for mates. After breeding, the female bears her young in a rocky alcove, where the offspring will remain for two-three months to be protected against predators.


Lincoln Park Zoo Celebrates Birth of Endangered Eastern Black Rhino

1 rhino

60 pounds, 30 inches (27 kg, 76 cm): Not your average measurements for a newborn.  But when you’re dealing with a baby Eastern Black Rhino, it’s fair to expect things to be a bit outsized. The 'little' rhino, a boy, was born August 26 at Lincoln Park Zoo in Illinois. He’s the first offspring for 8-year-old mom Kapuki and 27-year-old dad Maku and the first rhinoceros born at the zoo since 1989. Right now he’s growing behind the scenes, where animal care staff are keeping a close watch as the baby bonds with mom.

“Mother and baby are both doing wonderfully,” says Curator of Mammals Mark Kamhout. “The calf divides his time between nursing, following mom around, and napping, and that is exactly what a baby rhino should be doing.”

The new arrival is a welcome addition for a species that’s facing a conservation crisis in the wild. Black Rhinos are critically endangered and were nearly driven to extinction in the 1990s. Their wild population is currently estimated at 5,055 individuals. Although these creatures are protected, they are still killed illegally for their horns, which are used in folk medicines. 

Rhinos are naturally solitary—and territorial—animals, coming together only for brief intervals to breed. Introductions need to be carefully timed to the female's estrus so that she will be receptive to the male’s approach. The pairing of Kapuki with Maku was recommended by the Rhinoceros Species Survival Plan (SSP), a cooperative breeding and management strategy overseen by the Association of Zoos and Aquariums.

“This birth is cause for great celebration here at Lincoln Park Zoo and has been much anticipated,” says Kamhout. “The gestational period for rhinos is 15-16 months, and they have incredibly small windows for conception. Together with the zoo’s endocrinologists, we worked to pinpoint the exact window for Kapuki and Maku to get together for breeding. The whole zoo family is delighted at this successful outcome.”

So, how exactly do you pinpoint the right time? See and read more after the fold!

Tiny Takin Twosome Named at Lincoln Park Zoo

Tak duo 1

Not just one, but two baby Sichuan Takins have been born at Chicago’s Lincoln Park Zoo, arriving on January 31 and February 9 respectively. Both are males. Just yesterday it was announced that the babies have been named Xing Fu, meaning happy good fortune, and Mengyao, meaning superior handsomeness! Last week Lincoln Park Zoo's animal care experts picked six Mandarin names to honor the species’ roots, and put them out for a public vote.

The species is native to China and surrounding mountain ranges, where they graze on shrubs and grasses. They’re Vulnerable in the wild, a consequence of hunting and habitat loss. Lincoln Park Zoo manages the species in partnership with other zoos through the Sichuan Takin Species Survival Plan (SSP)®, a shared conservation effort managed by the Zoo’s general curator, Dave Bernier.

The addition of these two babies brings the Zoo’s Sichuan Takin herd  to five animals, along with their father, Quanli, who arrived from Montgomery Zoo in 2011 as part of an SSP breeding recommendation, and both moms, Jinse and Mei Li, a first-time mom who was born at the zoo herself in 2007. The herd will be on exhibit in the Antelope & Zebra area from 10 a.m.–2 p.m. for the next couple weeks as they adjust to life with the little ones.

All eyes are on newborn Gorilla at Lincoln Park Zoo

Gorilla 1

On October 11, a healthy baby Western Lowland Gorilla was born at the Lincoln Park Zoo – an important addition to this critically endangered species.

The baby has yet to be sexed or named and appears to be doing well. Mother Bana, 17, is showing appropriate maternal instincts, while dad Kwan, a 23-year-old silverback, is watchful over the mom and baby pair.

“We are cautiously optimistic about the new arrival. So far, Bana and the baby are showing all the signs of a happy, healthy mom-and-baby pair,” said Curator of Primates Maureen Leahy.

The new baby joins a troop of six individuals, all of whom are curious about the new arrival but maintaining a respectful distance as Bana and her offspring bond. According to animal care staff, the new mom is already establishing routines.

“Bana has been nesting in a quiet corner of the enclosure where she can nurture her infant,” said Leahy. “The baby is nursing regularly and demonstrating positive behaviors like reaching and gripping tightly.”

Zookeepers and vets will closely monitor Bana and her baby to ensure they continue to do well, as the first few weeks are critical in the survival of newborn Gorillas.

This Gorilla birth is the 51st in Lincoln Park Zoo’s proud history working with the species. It came about thanks to a recommendation from the Gorilla Species Survival Plan®, a shared management effort by zoos throughout the Association of Zoos and Aquariums.

It provides a welcome boost for a species that’s critically endangered due to habitat loss and hunting. In addition to work at the zoo, Lincoln Park Zoo also conserves Gorillas in the wild through the Goualougo Triangle Ape Project.

Rare Snakes hatched at Lincoln Park Zoo return to Illinois’ wild prairies

Snake3

Eighteen of the cutest creepy crawlers in Chicagoland were released into the wild on August 29 as part of a joint conservation effort by Lincoln Park Zoo and the Lake County Forest Preserve District that seeks to restore the Smooth Green Snake to its native prairie home.

Categorized as an Illinois Species in Greatest Need of Conservation, these tiny, jewel-colored snakes have drastically dwindled in population over the past few decades.

“Snakes need champions too,” said Lincoln Park Zoo Reintroduction Biologist Allison Sacerdote, Ph.D. “People like the warm and fuzzy animals, but it is important that conservation stretches across the entire ecosystem.”

After years of development across Illinois, the Prairie State has less than one percent of its original prairie intact.

“Our wildlife monitoring program revealed, that even in areas with the suitable habitat, Smooth Green Snakes were absent or extremely rare despite our habitat restoration efforts,” said Gary Glowacki, Wildlife Biologist of the Lake County Forest Preserve District. “The decline we have seen is largely due to habitat loss as prairies were converted into agriculture, urbanization, and the widespread use of pesticides.”

Essentially, the grasslands and the critters that call them home need all the help they can get.  In the case of the Smooth Green Snake, the help begins with a “head start” at the zoo. Animal care staffers provide optimum conditions for hatching and development so the snakes have a fighting chance when they are released.
