Brevard Zoo Keepers Raising Rare Oryx Calf

1_170330008

On February 28, Brevard Zoo welcomed its second Scimitar-horned Oryx calf of the year!

Unfortunately, first-time mother, Kitcha, displayed no interest in the female newborn. Tests performed the day after birth showed the calf had not yet nursed, and a decision was made to pull her from the exhibit. She is now living in an area where she can see and smell the rest of the herd, and she is currently being hand-reared by the Zoo’s dedicated animal care staff.

“She was quite small as a newborn, so we are monitoring her weight and food intake,” said Michelle Smurl, the Zoo’s director of animal programs. “For the first four days, she was eating every four hours. As her weight increases, we increase her food intake and she is now eating three times a day.”

Mom, Kitcha, was born at Brevard Zoo in 2009. The new calf’s father, Nuri, came from Smithsonian’s National Zoo and now lives at Lion Country Safari. Nuri also fathered the male calf born at Brevard on February 3.

The Scimitar-horned Oryx (Oryx dammah) is also known as the Sahara Oryx. It is a straight-horned antelope that stands just over 1 m (3.3 ft) at the shoulder. Both sexes have horns, but those of the females are more slender.

They are social and prefer to travel in herds. Their habitat in the wild was steppe and desert, where they ate foliage, grass, herbs, shrubs, succulent plants, legumes, juicy roots, buds, and fruit. They can survive without water for nine to ten months because their kidneys prevent water loss from urination (an adaptation to desert habitats). They can also get water from water-rich plants.

Both males and females reach sexual maturity at 1.5 to 2 years of age. Gestation lasts about nine months, after which a single calf is born, weighing 20 to 33 pounds (9.1 to 15.0 kg). Twin births are very rare. Both mother and calf will return to the main herd within hours of the birth. The female separates herself from the herd for a few hours while she nurses the calf. Weaning starts at 3.5 months, and the young become fully independent at around 14 weeks old.

Tiny Orphaned Dik-dik Hand-reared at Chester Zoo

Keepers step in to hand-rear orphaned baby dik dik antelope at Chester Zoo (17)
A tiny Dik-dik is making a big impression at Chester Zoo. The little Antelope is being cared for by zoo staff after its mother passed away soon after giving birth.

Standing only about 8 inches tall at the shoulders, the tiny Kirk’s Dik-dik is being bottle fed by staff five times a day. He will continue to receive a helping hand until he is old enough to eat by himself.

Assistant team manager Kim Wood and keeper Barbara Dreyer have both been caring for the new arrival, who is currently so light he doesn’t register a weight on the zoo’s set of antelope scales.

Kim said, “The youngster is beginning to find his feet now and is really starting to hold his own. We’re hopeful that, in a few months’ time, we’ll be able to introduce him to some of the other members of our group of Dik-diks.  He may be tiny but he is certainly making a big impression on everyone at the zoo.”   

Kirk’s Dik-diks grow to a maximum size of just 16 inches tall at the shoulders, making them one of the smallest species of Antelope in the world.

The species takes its name from Sir John Kirk, a 19th century Scottish naturalist, as well as the alarm calls made by female Dik-diks.  

Kirk’s Dik-diks are native to northeastern Africa and conservationists say they mark their territory with fluid from glands between their toes and just under their eyes, not dissimilar to tears. Populations in the wild are stable.

Visitors Watch Blesbok Give Birth

2BIOPARC Valencia - blesbok recién nacido - sept 2016 (2)Visitors to Spain’s BIOPARC Valencia on September 20 got a big surprise when a Blesbok gave birth to a calf in its zoo habitat.

Zoo guests watched the entire natural birthing process as the female Blesbok paced during her labor, then lay down to deliver the calf.

The little calf was alert from the moment it was delivered and positioned itself perfectly so mom could clean it off.  After a few unsuccessful attempts, the calf finally stood on wobbly legs.  The whole process was over in just a few minutes.

Because the delivery went smoothly, zoo staff members saw no need to intervene or assist with the birth.

In nature, these antelope live on South Africa’s grassy plains.  A prolonged labor and delivery could leave the mother open to predation by lions or hyenas.  The same is true for a newborn Blesbok calf – it must be able to walk and follow its mother within a few minutes of birth or be targeted by a predator.

Blesbok nearly became extinct about 150 years ago due to overhunting.  New hunting regulations allowed Blesbok numbers to increase, and the species is no longer threatened with extinction. 


Doubling-Up on Cuteness at The Maryland Zoo

The Maryland Zoo in Baltimore released news of two of its newest babies: a male Lesser Kudu calf (born June 18th) and a male Sitatunga calf (born June 25th).

The Kudu calf was born to six-year-old Lemon and sired by five-year-old Ritter. He currently weighs almost 19 pounds and has been named Jalopy.

The Sitatunga calf, named Chopper, weighed 13.1 pounds at his first health check. His mother is six-year-old Lela, and the father is eight-year-old Lou.

“The calves are being well cared for by their mothers inside their barns,” noted Margaret Inness, assistant general curator at the Zoo. “We like to give them time and space to bond during their early days and keep them as relaxed as possible for the health and wellbeing of all.”

Both calves now have limited access to the outdoor areas for a few weeks as they become acclimated to the yards and zoo visitors.

The Lesser Kudu calf had a few complications at birth, including a heart murmur discovered by veterinarians during his first health check. “This little guy had a bit of a rough start, but he’s nursing well and gaining weight as he should,” continued Innes. “Lemon is taking great care of him and we are pleased with his progress so far.”

Lesser Kudu (Tragelaphus imberbis australis) are one of eight species of African Spiral-horned Antelope. Male Lesser Kudu horns can grow to be 72 inches long, with 2 ½ twists. In the wild, they live in dry, densely thicketed scrub and woodlands of northern east Africa. Interestingly, they rarely drink water, apparently getting enough liquid from the plants that they eat.

At The Maryland Zoo, the Lesser Kudu herd of five can be found in the African Watering Hole exhibit, along with Addra Gazelle and Saddle-billed Storks.

The Sitatunga (Tragelaphus spekii) is a species of antelope native to Central Africa. They live in semi-aquatic swamps, marshes and flood plains. Outside of protected areas, Sitatunga are vulnerable to over-hunting and habitat loss, as people drain and develop swampland. Currently, however, Sitatunga are not classified as threatened or endangered.

The Maryland Zoo’s Sitatunga herd is made up of ten animals, including the new calf, and can be found in two exhibit spaces along the boardwalk in the African Journey section of the Zoo.

Both of the calves’ births are the result of a recommendation from the Species Survival Plan (SSP) for each species, coordinated by the Association of Zoos and Aquariums (AZA). SSPs provide breeding recommendations to maximize genetic diversity, with the goal of ensuring health of the individual animal, as well as the long-term survival of the species population to help save animals from extinction.

When a baby Blesbok born this summer at Spain's Bioparc Valencia wasn't able to get enough milk from its mother, zoo keepers stepped in to offer bottle-feedings to get the calf off to a strong start.

The little calf gulps down his bottles quickly and cooperates well at feeding time.

Blesbok are a type of antelope that live on the plains and grasslands of South Africa, preferably near water.  They live in herds, grazing on grasses and following the seasonal rains. 

Centuries ago, Blesbok herds stretched for miles across the grasslands, but they were hunted to near extinction in the late 1800s.  After hunting regulations were enacted, Blesbok numbers strongly rebounded and they are no longer threatened with extinction.

The name “Blesbok” is derived from the Afrikaans word for “blazed antelope,” a reference to the prominent white blaze on the faces of adults.

Impala Calves Leap Into Action

BIOPARC Valencia - Cría de impala saltando en la Sabana
The savannah at Spain’s BIOPARC Valencia is full of activity now that three Impala calves are running and playing with each other.

Born just a few weeks apart this spring, the Impala calves are part of the zoo’s small herd which mimics the social conditions these antelopes would experience in the wild.  Pregnant females separate themselves from the herd before giving birth. Calves are usually born at midday, and when the calves are a few weeks old, they rejoin the herd.  Young Impalas are grouped into nurseries, where they are watched over by adults.

Impala are native to eastern and southern Africa, where they inhabit woodlands and the edges of savannahs, often near water sources.  Only the males have the distinctive lyre-shaped, spiral horns, which are used during disputes with other males over territorial boundaries and mating rights. Impalas are generally active during the day, feeding on vegetation.

Impalas are not currently under threat, although like all wild animals, their habitat is slowly being encroached upon by growing human activity.  Fortunately, about a quarter of all Impalas live within protected parks and reserves in Africa.

See more photos of the calves below.

Three New Antelope Calves for the Maryland Zoo

1_Lesser kudu Meringue & calf Kaiser_JFB6906

The Maryland Zoo, in Baltimore, recently welcomed a male Lesser Kudu on December 18, 2015…the first Lesser Kudu to be born at the Zoo!

The Zoo also welcomed two more members of the genus Tragelaphus, female Sitatunga calves born on December 7 and Christmas Day, 2015. The girls are the third and fourth Sitatunga calves born this season at the Zoo, joining males Riri and Carl (born in April and June respectively).

The first of the female Sitatunga calves was born to two-year-old Remy and has been named Jess by zookeepers. She currently weighs approximately 21 pounds. The second female calf, named Noel, weighed almost 15 pounds at her last health check. Her mother is two-year-old Mousse. Eight-year-old Lou sired both girls.

“Both calves are healthy and are being well cared for by their mothers, inside the warmth of the Africa Barn,” stated Carey Ricciardone, Mammal Collection and Conservation Manager at the Zoo. “As a first time dam, Mousse is very protective of Noel, but Remy is a much more relaxed mother.”

Both calves will remain behind the scenes in the barn until warm weather returns.

The male Lesser Kudu calf, Kaiser, was born to two-year-old Meringue and sired by five-year-old Ritter. “This little guy has long, spindly legs and huge ears right now; he’s adorable,” continued Ricciardone. “Meringue is taking great care of him and we are pleased with his progress so far.”

Kaiser stands about three-feet-tall and weighs in at 26 pounds. He will also remain off exhibit with his mother until spring.

Yellow-backed Duiker Born at Virginia Zoo

1_VAZoo_YellowbackedDuiker2

There is more news to report from the Virginia Zoo. A Yellow-backed Duiker was born there last week! The female calf was welcomed by mother, Dot, and father, Dash, and weighed 11.4 pounds at birth.

Dot arrived at the Virginia Zoo in early 2013 (via the Houston Zoo) and recently turned 5 years old. Dash is her younger-man at 2 years old, and he came from the Metro Richmond Zoo in 2014.

So far, Zoo staff have observed Dot nursing, cleaning and caring for her baby… all evidence she’s doing a great job. The family is currently being kept indoors, which gives them time to establish the needed familial bonds; and it allows the baby to stay warm in these cold winter days.

The Yellow-backed Duiker (Cephalophus silvicultor) is a forest dwelling antelope found mainly in Central and Western Africa.

At maturity, they weigh a max of about 60-80 kg (132-176 lbs.). They feed selectively on plants, but their main diet is fruits.

Yellow-backed Duikers are the largest of all the duikers (primitive antelope which diverged early in bovid history). Both males and females have short cylindrical horns, which are ribbed at the base, and reddish-brown hair sits between the horns.

The species is listed as “Least Concern” on the IUCN Red List of Threatened Species, with a total population estimated at more than 150,000. According to the IUCN: “In much of its range, especially outside protected areas, it has been reduced to low numbers or eliminated by forest destruction, and encroachment of human settlements, coupled with uncontrolled hunting for bushmeat. The species was formerly subject to strict taboos that once protected it in some parts of its range, and it is still considered a non-preferred game species in some areas; however, many of these taboos have broken down.”


Rare Antelope Calf Born at Taronga Zoo

Bongo Calf (8)Taronga Zoo is celebrating the arrival of an Eastern Bongo calf, one of the rarest antelope species in the world.

Born in the early hours on February 8th, the calf has had time to bond with its mother, off display, before coming out onto exhibit for the first time.

Keepers are yet to determine the sex of the calf, which is the third born to mother, ‘Djembe’, and father, ‘Ekundu’.

“Djembe is a fantastic, protective mother and cleaned the calf as soon as it was born. The calf has already learnt to follow its mother around and was very curious and energetic when exploring its exhibit for the first time,” said Ungulate Keeper, Tracy Roberts.

Tracy said the new calf was an important addition to the Australasian breeding program, helping to save the critically endangered species from extinction.

“Every birth of a healthy calf is important, with fewer than 100 of these gentle animals left in the wild. Sadly Eastern Bongo numbers have collapsed due to poaching, disease and destruction of their native habitat in Kenya’s highlands,” she said.

Taronga is also helping to protect Bongos in the wild through its support of the Bongo Surveillance Project in the highlands of central Kenya. The project monitors herds and individual Bongo movements using visual signs, camera traps and GPS equipment and also combats poaching activities by removing illegal traps and snares.

Nyala Calf Gets Her Shots at Zoo Miami

Nyala Baby B“This won’t hurt a bit!”  That's what the veterinarian might have said to Zoo Miami’s week-old Nyala calf on vaccination day.  The female calf, born on February 5, endured her shots and was proclaimed in good health after her neonatal exam.

The newborn Nyala weighed about 13 pounds and has a lot of growing to do.  These antelope, which are native to southern Africa, weigh between 120-300 pounds as adults.  Males are larger than females and sport spiral-shaped horns, which are used in ritual fights for dominance during mating season. 

Nyala populations in Africa are relatively stable, though habitat loss and competition with domestic cattle pose some threat.  These antelope prefer woodlands and dense thickets that offer cover from predators like Lions and Leopards.  About 80% of Nyalas live in protected areas and parks, but mature male Nyalas are sought as game trophies.
