First Porcupine Twins for Cotswold Wildlife Park

1_Porcupettes 8

Cotswold Wildlife Park is celebrating the birth of the first Porcupine twins in the Park’s forty-seven-year history!

The as-yet-unnamed and unsexed twins were born recently to first-time mother, Stempu, and father, Prickle. The newborns are currently on show in the enclosure they share with a trio of inquisitive Dwarf Mongooses.

According to Cotswold staff, the twins are perfect miniature versions of the adults, even born with a full set of quills, which begs the question visitors have been keen to ask keepers: “How does the female give birth without injury?” After a gestation period of approximately one hundred and twelve days (the longest gestation period of any rodent), the female gives birth to offspring covered in soft, moist and flexible quills, enclosed in a thin placental sac. Immediately after birth, the quills quickly harden in the air and become prickly. The babies, also known as Porcupettes, are also born relatively well developed, with eyes open and teeth present.

African Crested Porcupines (Hystrix cristata) are the largest of the twenty-five Porcupine species. They are also the third largest rodent in the world, behind the Beaver and Capybara.

Their Latin name means, “quill pig”. Porcupines possess a spiny defense that is unique among rodents: approximately thirty thousand sharp quills adorn their back. Contrary to popular belief, they cannot fire their quills at enemies, but the slightest touch can lodge dozens of barbed quills into a predator’s body. Quills are modified hairs made of keratin (the same material as human hair, fingernails and the horn of a Rhino). Each quill can boast up to eight hundred barbs. If threatened, Porcupines reverse charge into a predator, stabbing the enemy with its sharp quills. The resulting wound can disable or even kill predators including Lions, Leopards and Hyenas.

Pair of Porcupettes Born at Utica Zoo

Utica Zoo is excited to announce the birth of two African Crested Porcupines. The delightful pair of “porcupettes” were discovered on May 1 with their parents, Kutarna and Darius. At their neonatal vet exam, they were determined to be a male and a female.

Mom Kutarna is 7-years-old and has been at the Zoo since 2010. Dad Darius is 6-years-old and has been at Utica for about the same time. Although the two have lived and bred with each other for about 4 years, they have never produced young until now.

The species has a gestation period of 93 to 94 days, after which one to three young are born, just 300 to 350 grams and about 6 inches long.

“When I came in that morning and discovered two new adorable faces snuggled in with their parents I was so excited” said Kristy Bussard, one of the Porcupines’ zookeepers.

The Association of Zoos and Aquariums’ (AZA) Species Survival Plan (SSP) encouraged the breeding of Kutarna and Darius. The SSP works to promote genetically diverse populations of African Crested Porcupines. These are the first offspring for this pair, although Darius sired another porcupette with a different female 5-years-ago. That animal, known as Joey, is one of the Zoo’s ambassador animals in the Education Department.

Porcupettes are born with soft quills that slowly become stiffer, more sharp, and longer with time. Once Porcupines have their armor and size, they have very few natural enemies.

“They are born so vulnerable, so we wanted to hold off on their public debut until we were more certain they had their natural defenses in place”, added Pearl Yusuf, Director of Animal Operations. “Because of their size and no protective quills, they could easily fall prey to native raptors like hawks that fly over the exhibit.”


First Prehensile-tailed Porcupine Birth for Zoo

The El Paso Zoo welcomed a new baby into their South American Pavilion exhibit. A Prehensile-tailed Porcupine was born on September 16 to mom, Flower, and dad, Vito.

This is first offspring for the parents and the first baby Prehensile-tailed Porcupine born at the Zoo.

El Paso Zoo keepers are waiting to name the baby porcupine (or porcupette) as soon as the sex is determined in a few weeks.

“Animal care staff were excited getting ready for the first Prehensile-tailed Porcupine birth at the Zoo since they confirmed the pregnancy,” said Collections Supervisor, Tammy Sundquist. “It’s always a joy getting to watch a baby grow and the animal care staff is monitoring Flower and baby closely.”

Flower and her baby are bonding behind the scenes and will be on exhibit next month.

The Prehensile-tailed Porcupines (Coendou prehensilis) are native to Central and South America. They are closely related to the other Neotropical tree porcupines (genera Echinoprocta and Sphiggurus).

Among their most notable features is the prehensile tail. The front and hind feet are also modified for grasping. These limbs all contribute to making this species an adept climber, an adaptation to living most of their lives in trees.

Prehensile-tailed Porcupines fee on leaves, shoots, fruits, bark, roots, and buds. Because of their dietary preferences, they can be pests of plantation crops.

They make a distinctive "baby-like" sound to communicate in the wild.

Very little is known about how these porcupines court each other, and they also have no regular breeding season.

A female usually gives birth to a single offspring. The baby is hairy, reddish-orange, and weighs about 14 ounces at birth. They are born with eyes open and can climb almost immediately. The spines will harden within about one week of birth, and in time, the baby porcupine will change color.

Females nurse their young until about 3 months of age. The young will reach adult size in less than a year and will reach sexual maturity in less than two years.

Adults are slow moving and will roll into a ball when threatened on the ground. The record longevity is 27 years old.

This birth is part of a breeding recommendation from the Association of Zoos and Aquariums (AZA) Species Survival Plan® (SSP) to aid in the species’ conservation. Prehensile Tailed Porcupines are not listed as threatened or endangered, but they are pressured by habitat loss and killed in parts of their range by hunters.

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.


Binghamton Zoo Has a Lucky 'Clover'

1_2016_porcupine_baby4

The Binghamton Zoo at Ross Park, in New York, is proud to announce the birth of a Prehensile-tailed Porcupine on March 17 to second-time parents Mattie and Zoey.

In honor of its day of birth, St. Patrick’s Day, the porcupette has been named Clover!

This birth is a major success for the Prehensile-tailed Porcupine’s Species Survival Plan. Mattie arrived at the Binghamton Zoo in November 2014, under recommendations from the SSP as a breeding candidate for Zoey. Mattie and Zoey successfully had Norwan on Father’s Day 2015 and now are caring for their newest addition.

Each SSP carefully manages the breeding of a species to maintain a healthy and self-sustaining captive population that is both genetically diverse and demographically stable. The Binghamton Zoo is proud to be a contributor to the captive population and is eager to continue participating in the program.

Zoo officials have been monitoring the progress of the porcupine and its parents. Weighing in at 410 grams, the baby has progressively gained weight since birth. The porcupine will not be sexed for several more weeks.

Porcupines are not born with sharp or barbed quills. Instead, the quills are soft and bendable, gradually hardening in the first few days after birth. Their quills will reach maturity after ten weeks. They are dependent on mother for nutrition the first four weeks after birth, eventually foraging for other food sources and will then be completely weaned at 15 weeks.

Prehensile-tailed Porcupines are found in South America. They feed on the bark of trees, buds, fruits, roots, stems, leaves, blossoms, seeds, and crops like corn and bananas.

The new porcupine is currently on exhibit with parents, Zoey and Mattie, and sister Norwan-- in the New World Tropics building.


Meet the National Zoo's Newest (and Prickliest) Baby

On October 5, Smithsonian’s National Zoo welcomed its newest (and prickliest) baby: Charlotte, the Prehensile-tailed Porcupine!

Whenever the zoo welcomes a baby animal, keepers work closely with veterinarians and nutrition staff to ensure newborns are healthy. For Charlotte, this meant regular weigh-ins to ensure that she was nursing and gaining weight. Vets gave her a clean bill of health during her first wellness exam, but then she began to lose weight. The animal care team determined that Charlotte was not able to nurse properly and was therefore not receiving enough milk.

The zoo’s nutrition staff created a formula using a mixture of puppy milk replacer, exotic milk replacer,  and egg whites, which resembled the composition of North American Porcupine milk. Once they were able to express milk from Charlotte’s mother, nutrition staff compared it to the formula to ensure Charlotte was getting the nutrition she needed.

To manage Charlotte’s dietary and medical needs, zoo vets surgically inserted an esophagostomy tube and fed her formula every three hours, around the clock, for five days. The feeding tube was removed on November 11 because Charlotte was consistently eating all of her diet by mouth. Today, at 2.8 pounds, Charlotte is healthy and developing normally.

Native to the forests of South America, Prehensile-tailed Porcupines feed on leaves, flowers, and tree bark.  Their prehensile (grasping) tails are not covered in spines and help these animals climb about in trees.  When threatened, these rodents curl into a ball, erecting their spines to appear larger and more intimidating.  They cannot shoot their spines (nor can any Porcupine), but the spines are loosely attached and can become painfully embedded in an attacker.

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 birth of this porcupine is a major success for the Prehensile-Tailed Porcupine’s Species Survival Plan. The father, Mattie, came to the Binghamton Zoo in November 2014, under recommendations from the SSP as a breeding candidate for Zoey. Each SSP carefully manages the breeding of a species to maintain a healthy and self-sustaining captive population that is both genetically diverse and demographically stable.

Baby porcupines (also known as porcupettes) are not born with sharp or barbed quills. Instead, the porcupette’s quills are soft and bendable, gradually hardening in the first few days after birth. Their quills will reach maturity after 10 weeks. They are dependent on the mother for nutrition the first 4 weeks after birth, eventually foraging for other food sources. They are completely weaned at 15 weeks.

These porcupines have a prehensile tail that allows them to grasp branches for balance. They also have long, curved claws that enable excellent climbing abilities. They spend most of their time in trees and will den in tree nests, rock crevices, brush, logs, and tangled tree roots.

Prehensile-Tailed Porcupines are native to South America. They feed on the bark of trees, buds, fruits, roots, stems, leaves, blossoms, seeds, and crops like corn and bananas. At the zoo, the porcupines’ diet consists of yams, carrots, greens, and leaf eater biscuits.

The porcupette is currently on exhibit with its parents, Zoey and Mattie, in the New World Tropics building.


Turtle Back Zoo Welcomes Baby Porcupine Just in Time for Mother’s Day

Turtle Back Zoo Porcupine Baby

The Turtle Back Zoo, in West Orange, NJ has some exciting news to announce! Mommy Porcupine Becky has given birth to a baby Porcupine- otherwise known as a porcupette! Born on April 16, 2015 both mother and baby are now officially on exhibit, just in time for Mother's Day.

While their Latin name technically means “quill pig,” Porcupines are actually rodents. These sharp dressed mammals are covered with soft hair as well as quills, which are really modified hairs that stand up when a Porcupine feels threatened. Not only does this make the Porcupine look larger, but it also delivers a prickly poke to a predator who gets too close. Sharp, strong teeth allow these herbivores to crack open nuts and eat barks, roots, fruits and leaves. There are about 12 different porcupine species, and they can be found in North, Central and South America; Southern Europe; Asia; and regions of Africa.

New Guy at Staten Island Zoo ‘Gets to the Point’

The male was born in early January and was donated to Staten Island Zoo by the Bright’s Zoo, in Tennessee, on recommendation of the Association of Zoos and Aquariums (AZA) Species Survival Plan (SSP) Program.  The new guy has been given the African name, ‘Bintu’, which means “precious/beautiful one”.

The African Crested Porcupine is the largest rodent in Africa. It lives in hilly, rocky habitats in sub-Saharan Africa, North Africa and Italy. “Porcupine” comes from the Latin ‘porcus’ for pig and ‘spina’ for spine. The name was given based on their appearance, as porcupines are not related to pigs.

Porcupines primarily eat roots, tubers, bark and fallen fruit. They are also known to eat cultivated root crops, and they are considered agricultural pests in some areas.

Wild predators include owls, leopards, and pythons. The porcupine warns predators to retreat by stamping their feet, clicking teeth, growling or hissing, and raising their quills and vibrating them to produce a rattling sound. If the predator doesn't retreat, the porcupine will run backwards and ram their attacker with the quills. Scales on the quill tips lodge in the skin of the predators, much like a fishhook, and become difficult to remove.

Crested Porcupines are terrestrial. They seldom climb trees, but they are able to swim. They are also nocturnal and monogamous. Porcupines prefer to reside, solitarily, among roots and rocks, and will often inhabit holes made by other animals. They reserve the use of burrows for larger family units.

Female Crested Porcupines will, generally, have only one litter per year. After a gestation period of about 66 days, one or two well developed young will be born in a chamber within a family burrow. The young weigh about 1,000 grams (2.2 lbs), at birth. They will leave the den, under adult supervision, about one week, after birth. Crested Porcupines reach adult weight (13-27 kg or 29-60 lbs.) at one to two years of age, and they are often sexually mature just before then.

They are currently classified as “Least Concern” on the IUCN Red List.
