A Wolf Pup for Zoo Zurich!

Wolf n mom

A Mongolian wolf pup was born April 25th, 2013, at Zoo Zurich in Switzerland. Zoo keepers had prepared a den (with a hidden camera) for the first time wolf mother, but she used it for only several days. She soon took her pup to different dens the wolves had burrowed themselves. According to keepers, the small female pup has an independent streak, preferring at times to wander around alone. As she grows older, she'll learn to adjust to life within the pack.

The mating season for wolves is approximately from December to January, starting when wolves reach maturity at two years of age. Gestation takes about 65 days and often produces 4-7 offspring in a litter. Wolves can live up to 20 years.

The Grey Wolf and its subspecies, such as this pup, once ranged over most of North America, Europe, and Asia, but have been pushed to the northern boundaries of most of these continents by habitat destruction and eradication efforts. These wolves share a common ancestry with domestic dogs and live in packs. Group life requires a versatile and precise language. Members of a Wolf pack communicate with visible signals such as ear position, baring teeth, fur bristling, and tail position. But there are also olfactory signals, such as urine or feces; audible signals, such as growling, whining, and howling; and tactile signals like snout poking.

White Canadian Wolf Parents Have a Play Day with Their Five Pups

Wolves parents

Whose little feet are those? They belong to one of the new White Canadian Wolf pups born at Berlin Zoo. On April 29, keepers noticed that the four-year-old Ava, who had been pregnant, emerged from the wolf cave looking considerably leaner. It was not long before five pups ventured out to be seen by staff and visitors alike. They sport their puppy coat of brownish spotted fur, but in time will come to have the magnificent white coat of their parents.

The Arctic or White Wolf inhabits the Canadian Arctic and the islands, parts of Alaska and northern parts of Greenland. All wolves in Canada are members of the species Gray Wolf (Canis lupus). Like those in the U.S., Canadian wolves can range from coal black to off-white in color, but most have a creamy white coat. The white hair shafts have more air pockets than those with pigmentation, therefore providing better insulation in a climate that at best is cool in mid-summer but can become absolutely frigid in the dark of their long winter.

Canadian wolves are usually larger than their counterparts in the United States, an adaptation that came about because the north has much larger prey, like caribou and moose, compared to the US wolves who feed on smaller mammals. Wolf packs tend to be larger in Alaska and Canada - up to 10 or even 20 animals per pack.

Knuthenborg Park Welcomes Five White Arctic Wolf Pups for the Second Year in a Row

  Mom and pup

A big event happened at Knuthenborg Safari Park at the end of April, for the second year in a row: five White Arctic Wolf pups were born to the park's four-year-old female Wolf after a gestation of 63 days. The pups have been found to be healthy and all are thriving. The sex of each pup is still unknown. Head animal keeper Lisbeth Høgh said, "This time we did not know she was pregnant when we never saw any mating."

They have just begun to emerge from the den but have come out more and for longer periods of time each day to play and nurse. It will be awhile yet before they begin to eat with the rest of the pack. The pups will develop long canine teeth for killing and eating prey.

In the wild, Arctic Wolves, also known as Snow or White Wolves are found in the Canadian Arctic, Alaska and the northern parts of Greenland. They are the only subspecies of the Gray Wolf that still can be found across its original range, because they rarely encounter human beings in their harsh, remote habitat. Not much has therefore been learned about their habits. However, this has been of benefit to them, as they are fairly safe from the encroachment of man, whether that takes the form of hunting or habitat destruction. As a result, the Arctic Wolf is also the only subspecies of wolf which is not threatened.

Endangered Mexican Gray Wolf Pup Pair Hand Reared at Mesker Park Zoo

Wolf 7 days old FB2

A litter of Mexican Gray Wolves, the most Endangered wolf species in the world, came to the Mesker Park Zoo & Botanic Garden -- and not by conventional means. They arrived on a LightHawk* flight at Tri-State Aero, Inc. and were immediately given into the care of zoo staff. The pups are doing well.

Born on May 8 at the Wolf Conservation Center in New York, the pups were pulled within hours of their birth with the goal of being in the care of the Mesker Park Zoo within 24 hours. There they have experienced Wolf parents standing by. The plan is for the pups to be partially hand reared and then, within a few months, be fostered by the resident Wolf parents. This is considered their best chance for surviving and contributing to the genetics of this Endangered species.

Although their genetically important birth mother was successful with one litter in her lifetime, her other litters have been totally lost or large portions of her litters lost within the first few weeks of life. The reasons behind these deaths are not known, so the arriving litter is considered fragile by the U.S. Fish and Wildlife Service (USFWS) and Mesker staff. The decision was made to pull any pups she produced this year and foster them via an experienced pair was reached in July by the USFWS and the Mexican Gray Wolf Species Survival Plan in consultation with Dr. Susan Lyndaker Lindsey, Animal Curator at Mesker Park Zoo & Botanic Garden and Behavioral and Husbandry Advisor to the USFWS Mexican Gray Wolf Recovery Program and the Species Survival Plan.

Dr. Lindsey has previous experience rearing wolf pup litters that are not socialized to humans and fostering them to adult wolves to form packs.

Selection of the initial wolf parents for Mesker Park Zoo & Botanic Garden was based upon the need for an experienced pair of wolves and the unique conservation contribution that Mesker Park Zoo & Botanic Garden could offer to the future of this critically Endangered wolf. The male Wolf, Nagual, was born on May 4, 2005 at Wild Canid Survival and Research Center in MO. On May 22, 2009, he was transferred to a USFWS Sevilleta Wolf Management Center, Sevilleta National Wildlife Refuge, NM. Dr. Lindsey fostered two orphan wild born pups to this male later that year. The female was born on April 22, 2007 at the California Wolf Center near Julian, CA. She was transferred to the USFWS Sevilleta Wolf Management Center, Sevilleta National Wildlife Refuge, NM on Nov. 23, 2009 and later placed with Nagual.

This pair had pups in 2010 and 2011 and raised them all successfully in a large pack. They have proven to be excellent parents.

There are only approximately 300 Mexican Gray Wolves in captivity and 60 to 70 in the wild in Arizona and New Mexico. These wolves have also been recently released in Mexico.

Red Wolf Pups Saved from Deadly Virus at Jackson Zoo

When an aggressive virus strikes, there’s often little that can be done. Fortunately, Jackson Zoo’s dedicated animal care team was able to give the medical attention needed to rescue a litter of Red Wolf pups from a virus that had been transmitted by the pups' mother, Taladu.  

The five pups, Jackson Zoo's first litter of this critically endangered species, were born on April 22nd. The three surviving pups are male and thriving under the care of zoo veterinarian, Dr. Michael Holifield. They are growing quickly and taking two to three ounces of formula at three-hour intervals. At three weeks old, two cubs weighed in at 2.3 lbs and one weighed in at 3 lbs. 

Because the virus was transmitted by their mother, they will continue to be hand-raised by Dr. Holifield for a few more weeks before they return to their nursery at the zoo.

Critically Endangered Red Wolf Pup Gets a Wild Foster Mom

Red wolf

In late April, a Red Wolf pup was born at the U. S. Fish & Wildlife Service’s Red Wolf Recovery Program facility in Alligator River National Wildlife Refuge, North Carolina. Born in captivity, the little female was the only surviving pup of her litter. The Red Wolf Recovery Program has taken this opportunity to introduce the pup to a wild litter of pups.

Since 2002, the Red Wolf Recovery Program has been successfully fostering pups into wild litters to help increase the genetic diversity of this critically endangered species. The attempts have been a great success: no wild wolf mother has ever been known to reject a foster pup. The survival rates of fostered pups also seem to be the same as their wild-born littermates’.

The captive-born pup was introduced into a litter of two females. Conservationists worked quickly and carefully to remove all pups from the den while the mother was away. They collected blood samples to keep track of parentage and implanted a microchip in each pup. When the wolves are older, they will be captured for a radio-collar fitting, and a quick scan of the microchip will allow USF&W to identify the wolf without temporarily holding it in captivity. Once the foster pup was masked with the scent of her littermates’ urine, all three were returned to the den to wait for their mother’s return.

There are several factors that can determine the likelihood of successful fostering. Ideally, the pups need to be no older than two-weeks of age at the time of the fostering.  During this time, the strong maternal instinct of the mother decreases the likelihood of pup rejection. The pups have limited mobility at this age as well, which ensures they will stay in or nearby the den site and the mother.  All the pups need to be similar in age, to reduce any one-sided competition for food.  Lastly, a good potential foster mother usually has a relatively low number of pups in her litter, ensuring that she will be able to care for the new addition.

Once common throughout the eastern and south-central United States, Red Wolf populations were decimated by the early part of the 20th century as a result of intensive predator control programs and the degradation and alteration of the species' habitat. The red wolf was designated an endangered species in 1967, and shortly thereafter the U.S. Fish and Wildlife Service initiated efforts to conserve the species. Today, more than 100 red wolves roam their native habitats in eastern North Carolina, and nearly 200 red wolves are maintained in captive breeding facilities throughout the United States.


Wolf Pup Gets a New Home in Colorado

Kenyi, a British Columbian Tundra Wolf pup, has a new home after traveling across the country to the Colorado Wolf and Wildlife Center.  Born in Florida, Kenyi and his two siblings were unplanned, so there was not enough room for them to remain at their birthplace.

The sanctuary’s staff has already started introducing Kenyi to some of its resident wolves, albeit through the safety of a fence. 

The Colorado Wolf and Wildlife Center is a sanctuary for a variety of canids, including Timber Wolves, Alaskan Wolves, Arctic Wolves, Mexican Grey Wolves, Swift Foxes, and Coyotes.  The sanctuary is accredited by the Association of Zoos & Aquariums (AZA). 

As an AZA facility, the center supports conservation efforts by participating in Species Survival Plan programs for Mexican Grey Wolves and Swift Foxes.

 

UPDATE: Maned Wolf Pups Come Out of Hiding to Visit the Vet

Two Maned Wolf Pups born at the Czech Republic’s Zoo Liberec on January 10 had their first visit to the veterinarian this week to receive vaccinations and determine their gender.  The pair, a male and a female, was proclaimed in excellent health by the veterinary staff. 

The pups, who were profiled on ZooBorns last month, weighed only about a pound (.5 kg) at birth, but they have rapidly gained weight.  At the exam, each weighed more than six pounds (2.8 kg). The pups are the first Maned Wolves ever born at Zoo Liberec.

Native to South America, Maned Wolves are unique among canids.  They are distinguished by long legs, a bushy mane which is erected when the Wolf is threatened, and a skunk-like odor.  Maned Wolves live solitary lives roaming the grasslands of central South America.  They eat small mammals as well as tubers, fruits, and sugarcane.

Maned Wolves are listed as Near Threatened by the International Union for Conservation of Nature (IUCN), but in some parts of their range, notably in Uruguay, this species may be nearly extirpated (locally extinct). 

 


Wolf Quints Make Their Debut

Five furry European Grey Wolf pups made their debut last week at Scotland’s Highland Wildlife Park.  Born on May 25 to mum Elara and dad Puika, the still-shy six-week-old pups are starting to explore their forested habitat, aptly named Wolf Wood.   It’s been 12 years since Wolves were born at the park.

The pups’ genders are not yet known, but park officials have already decided to name one of the pups “Forty,” in honor of the park’s 40th anniversary.   

 “The pups, especially one particularly bold individual, are now beginning to wander around the large wooded enclosure, which does seem to cause their mother some anxiety,” said Douglas Richardson, Animal Collection Manager.  “The Park is visited by quite a number of people with a special interest in Wolves and it is hoped that this latest breeding success will generate further interest in this much-maligned species, especially as it is an animal that formerly roamed over most of the country.”

Wolves were once common throughout Europe, but in the 1800s, they were eliminated in most of central and northern Europe.  Since then, Wolves have been reestablished in some parts of the region, despite threats from overhunting and poaching.  Today, the largest wild European Grey Wolf populations are in the eastern European countries of Poland and Romania, and in the Balkans.

Artic Wolf Pups Emerge at Knuthenborg Safari Park

Yip

They were born on May 7, but these Arctic Wolf pups were just seen coming out of their cave by keepers for the first time at Knuthenborg Safaripark in Denmark.

Just three puppies were spotted peeking their heads out at the edge of their den... but then came two more fuzzy little heads. "We are really happy", says Animal and Dissemination Manager for Knuthenborg Safari Park, Lisbeth Hoegh. "We had, at best, hoped for three pups, but there are five! Unusually large broods indicate a wolf-mother who works well in her role."

The Arctic Wolf is also called the Polar or White Wolf, and lives in the northernmost regions of Canada and Greenland. They are related to the Gray Wolf. They are considered endangered, due to being hunted for their beautifully colored soft pelts, among other reasons. In the wild they are very scarce, and there are even fewer in captivity.
