The colony of Little Penguins (Eudyptula minor) that debuted in 2015, as a new species at WCS’s (Wildlife Conservation Society) Bronx Zoo, has successfully produced a chick that is now on exhibit with the rest of the colony.

The chick hatched May 10, and this is the first time this species has bred at the Bronx Zoo, in the zoo’s 120-plus year history.

Known for their small size and characteristic bluish hue, Little Penguins are also known as Blue Penguins, Little Blue Penguins, and Fairy Penguins. Adults are only about 13 inches tall and weigh around 2 to 3 pounds. They are the smallest of the 18 penguin species and native to coastal southern Australia and New Zealand.

Little Penguins lay their eggs in burrows dug in sand, natural cavities, or under thick vegetation. They may even nest under man-made structures. Both parents care for and incubate the egg. Newly hatched chicks weigh just 25g. The chicks lose their downy plumage at about 50 days of age when it is replaced with waterproof feathers.

With the exception of the new chick, all of the birds in the Bronx Zoo colony were hatched at the Taronga Zoo in Sydney, Australia and brought to the Bronx Zoo as part of a breeding program. Approximately 15 penguins a year hatch at Taronga, making it the most successful Little Penguin breeding program in the world. The Bronx Zoo penguins will help ensure continued genetic diversity in the Little Penguin populations in the U.S.

The species occurs in temperate marine waters and feeds on fish, cephalopods and crustaceans. They nest, colonially, in burrows on sand dunes or rocky beach areas. Like other penguin species, they use a wide range of vocalizations to communicate with each other. In the wild, their populations are threatened by climate change and human activities.

Turkmenian Flare-horned Markhor at WCS’s Bronx Zoo

1_Julie Larsen Maher_5483_Markhor and Kids_WAS_BZ_06 09 16

A herd of Turkmenian Flare-horned Markhor (Capra falconeri hepterni) roams the rocky terrain in their expansive habitat along the Wild Asia Monorail at WCS’s (Wildlife Conservation Society) Bronx Zoo.

The herd consists of eleven males (easily identified by their huge spiraled horns and distinct coats), ten females (which are smaller than the males and have much shorter horns), and their offspring, which includes eight kids born this year.

The Markhor is a unique species of goat found in the mountains of Afghanistan, India, Pakistan, Tajikistan, and Uzbekistan. They inhabit upper elevations, with vegetation as their food source. They are skilled climbers and will scale steep rocky terrain to escape predators such as snow leopards and wolves.

The Bronx Zoo’s Markhor live with a herd of Himalayan Tahr, another species of Asiatic mountain goat found in areas of China, Tibet, Nepal, and northern India.

Wild Markhor are threatened by human activity in the ranges where they live. Their impressive twisted horns and thick fur make them a target for trophy hunters and poachers. They are also susceptible to habitat loss from expansion of land used for domestic livestock, and from disease spread from the growing livestock population.

With support from US Ambassador Fund, Columbus Zoo Conservation Fund, and other supporters, WCS has been working to save wild Markhor in the mountains of northern Pakistan since 1997. Now working with 65 communities, WCS has seen a 70 percent increase in Markhor populations in the last decade, with estimates placed at 1,700 wild Markhor in this landscape—a significant proportion of the global population of this endangered mountain goat.

The WCS Pakistan Program’s recovery of Markhor in Pakistan has helped lead to the recent, nearly unprecedented two-stage down-listing of Markhor by the International Union for Conservation of Nature (IUCN) from an “Endangered” classification, passing the status of “Vulnerable”, to now being known as “Near Threatened”.

A North American Porcupine was born April 24 at WCS’s (Wildlife Conservation Society) Bronx Zoo and is now on exhibit with his family in the newly renovated Children’s Zoo.

The male porcupette was born to mother, Alice, and father, Patrick, and this is the pair’s fourth offspring.

The North American Porcupine (Erethizon dorsatum), also known as the Canadian Porcupine or Common Porcupine, is a large rodent in the New World Porcupine family. The beaver is the only rodent in North America that is larger than the North American Porcupine.

The Porcupine’s most recognizable physical characteristic is its spiky quills. They can have as many as 30,000 quills covering their bodies and use them as a defense against predators. Despite popular belief, Porcupines cannot shoot their quills. The quills of the North American Porcupine have a tiny barb on the tip that, when hooked in flesh, pull the quill from the Porcupine’s skin and painfully imbed it in a predator’s face, paws or body.

Gestation lasts for 202 days. Porcupines give birth to a single young. At birth, they weigh about 450 g, which increases to nearly 1 kg after the first two weeks. They do not gain full adult weight until about two years old.

At birth, the quills are very soft. They begin to harden a few hours after birth and continue to harden and grow as the baby matures.

Female Porcupines provide all the maternal care. For the first two weeks, the young rely on their mother for sustenance. After this, they learn to climb trees and start to forage. They continue to nurse for up to four months, which coincides with the fall mating season. They stay close to their mothers.

The North American Porcupine is listed as “Least Concern” on the IUCN Red List. It is common throughout its range, except in some U.S. states in the southeast part of its range. However, they are threatened by hunting and habitat loss. As of 1994, it was listed as an endangered species in Mexico.


Take a Peek at Bronx Zoo's Otter Pup

An Asian Small-clawed Otter pup made its public debut at the Wildlife Conservation Society’s Bronx Zoo in late April.

Born this spring, the pup is already dipping its toes in the family’s watery exhibit.

Like all Otters, the species is well adapted for a semi-aquatic life. Their elongated bodies and webbed feet make it easy for them to propel through the water. They have dexterous paws that aid in finding and consuming food, and their fur is extremely dense and waterproof for temperature regulation.

Asian Small-clawed Otters have a vast but shrinking Southeast Asian range that spans from India to the Philippines, Taiwan, and parts of southern China. The species is classified as Vulnerable by the International Union for Conservation of Nature and is threatened by habitat loss and exploitation.

 


Two Lemur Species Debut Offspring at Bronx Zoo

1_Julie Larsen Maher_5710_Ring-tailed Lemur and Baby_MAD_BZ_04 05 16_hr

The Madagascar! exhibit at WCS’s (Wildlife Conservation Society) Bronx Zoo is now home to three new Lemur babies.

Two Ring-tailed Lemurs (Lemur catta) and one Brown Collared Lemur (Eulemur collaris) were born in late March and have made their public debut. Both species live in a naturalistic habitat depicting the Malagasy Spiny Forest along with critically endangered Radiated Tortoises and several bird species including Vasa Parrots, Red Fodies, Grey-headed Lovebirds, and Ground Doves.

Guests hoping to catch a glimpse of the new additions will have to observe closely as young Lemurs cling to their mothers and nestle in their fur.

The Bronx Zoo has had tremendous success breeding Lemurs as part of Species Survival Plans, cooperative breeding programs designed to enhance the genetic viability of animal populations in zoos accredited by the Association of Zoos and Aquariums (AZA).

WCS works to save Lemurs and their disappearing habitat in the African island nation of Madagascar – the only place in the world where Lemurs are found in the wild.

Brown Collared Lemurs are native to the tropical forests of southeastern Madagascar. Ring-tailed Lemurs are native to the forests and bush in the south and southwestern portions of the island. Their habitats are being destroyed by human activity including charcoal production and slash-and-burn agriculture.

Ring-tailed Lemurs are very social and live in large matriarchal groups that often contain several breeding females. They are capable climbers, but spend much of their time on the ground. Newborns will ride on their mothers’ chest and back for the first few weeks and will begin move around on their own within two-to-four weeks, but still stay close to their mother.

Collared Lemurs use their long tails to balance when leaping through the forest canopy. They live in groups of males and females but are not matriarchal like many other Lemur species. The young ride on their mother’s back hiding in her fur for the first few months of their lives.

All Lemur species are in trouble due to devastating loss of suitable habitat. The International Union for Conservation of Nature (IUCN) classifies both Ring-tailed Lemurs and Brown Collared Lemurs as “Endangered” in the wild.

Otter Pup Ready for Fun at the Bronx Zoo

1_Julie Larsen Maher _3566_Asian Small-clawed Otters and Pup_JUN_BZ_09 04 ...

Monty, the Asian Small-clawed Otter pup, has been eagerly exploring his exhibit at the Bronx Zoo. In an effort to keep his curiosity from getting the better of him, mom and dad are never far behind.

It has been several years since a new otter pup has inhabited the Bronx Zoo’s Jungle World. Eleven-year-old mom, Jasmine, and nine-year-old dad, Gyan, are first time parents. So far, they have been doing an outstanding job with little Monty. Keepers have been giving them plenty of privacy and time to bond, only interrupting for quick weigh-ins to check the pup’s growth.

3_Julie Larsen Maher _3630_Asian Small-clawed Otters and Pup_JUN_BZ_09 04 ...Photo Credits: Julie Larsen Maher / WCSAside from his new desire to explore, Monty has started to eat solids and is getting better at swimming.  His parents take their jobs seriously. Jasmine continues to keep his nest in order, and dad has started bringing him bits of fish.

The Asian Small-clawed Otter (Amblonyx cinerea), also known as the Oriental Small-clawed Otter, is the smallest otter species in the world. Weighing less than 5.4 kg (11.9 lbs.), the species lives in mangrove swamps and freshwater wetlands of Bangladesh, Burma, India, southern China, Laos, Malaysia, Indonesia, Singapore, the Philippines, Thailand, and Vietnam.

The otter’s paws are its distinctive feature. The claws don’t extend beyond the fleshy end pads of its partially webbed fingers and toes, giving it a high degree of manual dexterity for feeding on mollusks, crabs and other aquatic animals.

Asian Small-clawed Otters form monogamous pairs for life. The mates can have two litters of one to six young per year, and their gestation period is about 60 days. Newborn pups are immobile, and their eyes are closed.  The pups remain in their birthing dens, nursing and sleeping, for the first few weeks. They open their eyes after 40 days and are fully weaned at 14 weeks. Within 40 days, the young start to eat solid food and can swim at three months. Young otters will stay with their mother until the next litter is born. Males assist females in nest building and food procurement.

The Asian Small-clawed Otter is classified as “Vulnerable” on the IUCN Red List. Threats to their existence in the wild are: habitat loss, pollution, and hunting. 


Bronx Zoo Announces Birth of Porcupette

The North American Porcupine (Erethizon dorsatum) is a large rodent whose most recognizable physical characteristic are its spiky quills. They can have as many as 30,000 quills covering their bodies. The quills are modified hairs that are sharp, barbed hollow spines. They are used primarily for defense but also serve to insulate the body during winter. Despite popular belief, porcupines cannot shoot their quills, but when threatened, the porcupine contracts the muscles near the skin which causes the quills to stand up and out. The quills have a tiny barb on the tip that, when hooked in flesh, pull the quill from the porcupine’s skin and painfully imbed in the predators skin.

Porcupines are herbivores and eat leaves, twigs, and green plants. In winter, they may also eat tree bark.

Female porcupines are solitary, except during the fall breeding season. They have a long gestation period that lasts for 202 days and typically give birth to just one offspring. Baby porcupines (porcupette) weigh about 450 grams at birth. At birth, the quills are very soft but begin to harden a few hours after birth. The quills continue to harden and grow as the baby matures.

The Bronx Zoo has a successful history breeding Gorillas as part of the Species Survival Plan, a cooperative breeding program designed to enhance the genetic viability of animal populations in zoos accredited by the Association of Zoos and Aquariums. These are the 16th and 17th Gorillas born at Congo Gorilla Forest; there have been 52 Gorillas born at the Bronx Zoo since 1972.

Layla (16 years old) gave birth on January 17, and Kumi (also 16 years old) had her baby on January 19. Ernie (32 years old) is the father of both babies. The gender of the infants is not yet known.  The babies join 17 other Gorlllas at the zoo.  

Gorillas are the world’s largest primates. Weighing only about 4 to 5 pounds at birth, adult males weigh between 350-450 pounds and when standing upright can be up to six feet tall. Adult females weigh between 150-250 pounds and are up to four feet tall. 

Western lowland Gorillas are designated as Critically Endangered by the International Union for Conservation of Nature. Their natural range spans tropical and subtropical forests in equatorial Africa. WCS works throughout Central Africa to protect Gorillas from habitat loss and illegal hunting.


Two Boys from the Bronx

Both cubs are male and were born May 6th to first-time parents. They are on exhibit, with their mother, in the 'Himalayan Highlands', which received the Association of Zoos and Aquariums Exhibit Award for outstanding design in 1987.

Snow Leopards are classified as “Endangered” on the IUCN Red List. They are among the world’s most endangered big cats, with only an estimated 3,500 to 7,500 remaining in the wild. Their range is limited to remote mountains of Central Asia and parts of China, Mongolia, Russia, India and Bhutan.

WCS’s Bronx Zoo is a world leader in Snow Leopard husbandry and participates in the Species Survival Plan, a cooperative breeding program designed to enhance the genetic viability of animal populations in zoos accredited by the Association of Zoos and Aquariums. The Bronx Zoo has had more Snow Leopard births (over 70) than any other zoo in North America and was the first zoo in the United States to exhibit the big cats in 1903.

WCS has worked for decades on Snow Leopard conservation programs in the field with current projects in Pakistan, Afghanistan, and western China. Past projects have also included work with Snow Leopards in Kyrgyzstan and Mongolia.

In Pakistan, WCS has been implementing a community-based conservation program since 1997 to help protect the Snow Leopard and other wildlife. The program includes education, training, and institution building for community resource management. WCS has helped create over 60 natural resource committees and trained over 100 community rangers to monitor Snow Leopards and other wildlife, in an effort to stop deforestation and poaching that threaten these species.


Orphaned Tigers Cubs Rescued in Russian Wilderness

Gallery_tiger_cub

Three orphaned Siberian Tiger cubs, alone in the snowy Russian Far East, were rescued from certain death last fall by the Wildlife Conservation Society (WCS), which operates the Bronx Zoo.  The capture and rehabilitation of the cubs – who are part of a rapidly vanishing species – illustrate the challenges of saving Tigers, one animal at a time.  Fewer than 500 Siberian Tigers, which are the largest of all Tiger subspecies, survive in the wild, including 330-390 adults.  Worldwide, only about 3,200 Tigers exist in the wild, and they face poaching, a reduction in prey species, and habitat loss.

WCS assisted Russian wildlife officials by deploying two of their staff members, brothers Kolya and Sasha Rybin, who are expert Tiger trackers. The cubs were seen stalking a dog near a small village, so the team knew where to start.  Fresh tracks led the team to the forest, where they found the cubs staring curiously at them from the middle of a road.  Moments later, the cubs vanished into the forest, but the team was able to capture the smallest cub, which weighed only 35 pounds.  The cubs were determined to be about four months old.

Researchers believe that the cubs’ mother was likely killed by poachers.  A 20-year WCS project determined that poaching accounts for nearly 75% of adult Tiger deaths.  Bones and body parts from a single adult Tiger can fetch up to $5,000 for the poacher alone, and once processed for use in traditional Asian medicine, far more.  Female Tigers with cubs seem to be the most vulnerable, because they will defend their cubs rather than flee.

These three cubs probably remained in the spot where their mother was killed, leaving only when they became too hungry to wait any longer.

The team was unable to capture the two remaining cubs for several days.  One was followed for 13 kilometers, yet managed to avoid capture until it ventured onto a military base.

The third cub eluded the team for two more days.  Weak and struggling to walk in the deep snow, the dehydrated animal was captured, warmed, and given fluids and food before making the four-hour trip to the rehabilitation center to meet his siblings.

Over the next seven to eight months, the Tiger cubs will have very limited interactions with people to avoid associating humans with food.  This spring, small prey will be introduced so that the cubs can learn to hunt. They will eventually be released in a remote part of Siberia – three living, breathing symbols of hope for this imperiled species.
