Point Defiance Zoo’s Penguin Siblings Swim On-Exhibit

1_95A0268

The two juvenile Magellanic Penguin chicks, at Point Defiance Zoo & Aquarium, recently slipped into the water of their on-exhibit pool and excitedly darted from end to end.

Members of the adult Penguin colony stood watch on the rocks above, squawking loudly, acting as black-and-white sentries warily guarding their turf from these upstart juveniles. “That’s normal behavior,” staff biologist Amanda Shaffer said. “Eventually, the adults will welcome the younger Penguins into their midst.”

In just 12 weeks, the chicks have grown from fuzzy balls, weighing just under 6 ounces, to recognizable Penguins almost as large as the adults from whose eggs they hatched.

According to zoo staff, the chicks have been off exhibit for a few weeks, gaining strength, getting accustomed to feeding schedules, and growing the coarse feathers and stiff wings needed for swimming. Point Defiance zookeepers have kept careful watch over the brother-and-sister pair as they learned to swim.

The siblings are now on-exhibit daily in the Penguin Point habitat at the zoo.

ZooBorns eagerly shared news and adorable pics of the Penguin siblings when their birth was announced earlier in the summer: Point Defiance Zoo Welcomes Magellanic Penguin Chicks”.

The chicks broke out of their shells on May 23 and May 25 and are the first Magellanic Penguins to hatch at the zoo since 2006.

The little Penguins aren’t given names. They are known by the colors of the bands on their wings. These two are the offspring of mother “Pink” and father “Red.” The male chick is banded as “Red/White” and the female is “Pink/Black.”

Point Defiance Zoo’s Penguin colony now numbers a total of ten: five males and five females.

“I’m pleased with their progress,” said Shaffer, the zoo’s lead Penguin keeper. “They are healthy and they did great while learning to dive into the off-exhibit pool, swim and then pull themselves out.”

Gentoo Penguin Chick Has ‘Big’ Happy Feet

It may only weigh a few pounds, but two of the biggest features of the Tennessee Aquarium’s newest Gentoo Penguin chick have already earned it an unofficial nickname.

Born on June 5 to experienced parents Bug and Big T., the large feet of the newest addition to Penguins’ Rock immediately inspired the moniker “Big Foot.”

“Our animal trainer Holly Gibson chose that name, and it is very fitting,” says Senior Aviculturist Loribeth Lee. “Besides his belly, the feet are the biggest thing on this guy right now! Penguin chicks have almost comically large feet until they grow into them. Having big feet helps Penguins to balance while they are so oddly shaped.”

This nickname is just a placeholder. It will be replaced by an official name, chosen from a crop of keeper-selected alternatives, during a public contest on the Aquarium’s Facebook page later this year.

Aquarium staff began noticing signs that the new chick was breaking out of its egg, a process called “pipping,” at 8 a.m. on June 5. The baby Gentoo was fully hatched at 3:30 p.m., a faster-than-average pace, Lee says.

The chick’s gender will remain indeterminate until November, when it can be properly assessed by staff during the colony’s next round of semi-annual physical exams. A drop of the chick’s blood will be sent to a lab, and the DNA results will be available a few days later.

For now, the Aquarium’s Penguin experts are closely monitoring the chick’s growth and health, Lee says.

“The first four weeks of a chick’s life are the most concerning, as there are lots of obstacles to overcome,” she says. “We will continue to keep a close eye on this little bird, especially making sure the nest stays clean and the chick continues to get fed by both parents.”

Until the arrival of its waterproof adult feathers in six to seven weeks, the chick will remain safely corralled with its parents behind a clear, acrylic “play pen.” This barrier around the nest keeps nosey neighbors at flipper’s length away and prevents the baby Penguin from accidentally tumbling into the water.

Despite the uncertainty of this early period in its development, so far the chick has exhibited robust vitals and a healthy appetite. And it is gaining weight at a healthy rate, which indicates the chick’s body should start catching up with its enormous feet soon.

“We like to see the chicks on the higher end of the weight range, as if they do have a drop in weight at any point, then it is less critical than a bird who is on the low end of the weight range,” she says.

The chick’s parents, Bug and Big T., are one of the exhibit’s most prolific breeding pairs, having successfully hatched four chicks: Roxie, Bobber, Rodan and Terk. In all, the residents of Penguins’ Rock have hatched 20 chicks since 2009.

“Even after seeing over 20 chicks hatch here, it never gets old,” Lee says. “It’s so exciting to have a new young one in the group and watching our guests enjoy their progress! The best part of my job is seeing thriving birds in the exhibit, and this one seems to be doing well so far.”

The chick will reach its full, adult size when it is about 75 days old and its full adult weight a few months later after its swim muscles develop.

Point Defiance Zoo Welcomes Magellanic Penguin Chicks

1_170602_pdza_18

Point Defiance Zoo & Aquarium recently celebrated the hatchings of two Magellanic Penguin chicks. After their first well check examinations, veterinarians determined the pair is healthy and thriving. They are the first Penguin chicks to hatch at the Zoo since 2006.

The first of the new chicks arrived on May 23 and weighed 5.3 ounces at the first exam. The second chick hatched on May 25 and weighed 3.9 ounces, staff biologist Amanda Shaffer said. Each chick was tenderly placed on a towel in a lightweight container and weighed on a portable scale.

“They both look great and were quite active during their physical examinations,” said Zoo Veterinarian, Dr. Kadie Anderson, after the first well check exam. Anderson carefully examined each chick for overall body condition and energy and hydration levels to assess their health.

The hatchlings are the offspring of 7-year-old mother “Pink” and 7-year-old father “Red.” The Magellanic Penguins at Point Defiance Zoo & Aquarium are not named but rather are known by the colors of the identification bands on their wings.

“Pink and Red are attentive parents,” said Shaffer, the Zoo’s lead Penguin keeper. “Pink often keeps watch over the burrow while Red broods the chicks, keeping them warm with a special patch on his abdomen that allows them contact with his skin. The father also has exhibited protective behavior and vocalizations”, said Shaffer.

The new little family of four is currently on exhibit in the Penguin Point habitat at the Zoo, but spotting the chicks will take patience. They’re safely hidden under one of the parents while they’re being kept warm during the day, coming out occasionally for feeding. The parents feed the chicks a slurry of regurgitated fish after the adults have eaten herring and capelin.

Point Defiance Zoo & Aquarium now has four male-female pairs of adult Penguins, and all have been sitting on eggs.

Parents incubate the eggs in shifts; they generally hatch between 38 and 42 days after they’re laid.

Meet Pedro & Perdy the Penguins

Two penguin Chicks 2 - Paradise Park

Two rare Humboldt Penguin chicks named Pedro and Perdy are being reared by keepers at Paradise Park Wildlife Sanctuary.

Penguins typically lay two eggs a few days apart. When the first chick hatches, it receives all of mom and dad’s attention. Penguin chicks are very demanding and squeal loudly as they appeal for food, which is regurgitated by the parents.  By the time the second chick hatches a few days after its sibling, the older chick, which may have nearly doubled in size by now, continues to get all the attention and parents may ignore the younger chick. The younger chicks in penguin nests often do not survive in nature.

Because Humboldt Penguins are rare, keepers took the Pedro and Perdy, who were both second chicks, into their care to ensure the birds’ survival.

Keeper Bev Tanner explains, “Pedro and Perdy are being hand-reared as often in a nest with two chicks only one is successfully raised by the parents. As this is an endangered species it is very worthwhile for us to take the second chick and rear it to increase our flock.”   

When chicks are in the nest, they have fluffy grey down feathers. They remain in the nest for about three months, at which time they have developed the waterproof plumage needed for swimming. Juveniles are grey and white, developing the distinctive black-and-white adult plumage at one year old. The pattern of dark speckles on the adult’s lower chest is unique to each Penguin and helps to identify each individual.

Humboldt Penguins are native to the western coast of South America, where they fish in the cold Humboldt current for which they are named.  They are listed as Vulnerable by the International Union for Conservation of Nature.  Historically, Humboldt Penguins were threatened by extensive mining for their guano (accumulated droppings), which was used for fertilizer. Today, the main threats are habitat loss and competition with invasive species.

Endangered Penguins Hatch at Zoo Vienna

1_PA_Felsenpinguin1

Since mid-April, Zoo Vienna Tiergarten Schönbrunn has welcomed eleven Northern Rockhopper Penguin chicks!

After about 33 days of incubation, the hatchlings were greeted by caring penguin parents that have since been providing all the food and warmth they need.

The species is currently classified as “Endangered” on the IUCN Red List of Threatened Species. Therefore, conservation efforts in zoos around the world are important for their survival.

"The Northern Rockhopper Penguin breeds on the island group around Tristan da Cunha, in the southern Atlantic, and is strongly endangered. The main causes of its threat are the overfishing and pollution of the seas, as well as climate change," explains Animal Garden Director, Dagmar Schratter.

Currently, only 96 Northern Rockhopper Penguins live in European zoos. The largest colony, with 45 adults, can be found in Schönbrunn. The Tiergarten also runs the European Conservation Program (EEP) for this endangered and distinctive penguin. Since 2004, the Tiergarten has delivered 41 Rockhopper Penguins to other zoos.

Schratter continued, "Through our many years of experience in breeding, we would like to help build up colonies in other zoos..."

The Northern Rockhopper Penguin (Eudyptes moseleyi) is also known as “Moseley's Rockhopper Penguin”, or “Moseley's Penguin”.

More than 99% of them breed on Tristan da Cunha and Gough Island in the South Atlantic Ocean. Rockhopper Penguins have been considered to consist of two species: Northern and Southern Rockhopper (research published in 2006 demonstrated morphological, vocal, and genetic differences between the two populations).

In the wild, the Northern Rockhopper Penguin feeds on krill and other sea life such as crustaceans, squid, octopus and fish.

The species prefers to breed in colonies in a range of locations from sea level or on cliff sides, to sometimes inland. An interesting difference between the two subspecies is their mating ritual. They both use different songs and head ornaments in their mating signals. The reproductive isolation has led to not only physical difference but also behavioral. Adults feed their chicks lower trophic level prey than they themselves consume.

A study published in 2009 showed that the world population of the Northern Rockhopper had declined by 90% since the 1950s, possibly because of climate change, changes in marine ecosystems and overfishing for squid and octopus by humans. Other possible factors in the decline include: disturbance and pollution from ecotourism and fishing, egg harvesting, and predation and competition from sub Antarctic fur seals. Surveys show that the birds are also at risk of infection by goose barnacles. House mice (Mus musculus) have also been introduced into their environment by human sea expeditions, and the mice have proven to be invasive, consuming Northern Rockhopper eggs, as well as hunting their young.


London Zoo Celebrates Arrival of ‘Easter' Chicks

1_Easter penguin chicks (ZSL London Zoo) (5)

The first of two Penguin chicks timed its arrival perfectly, at ZSL London Zoo, by hatching on Easter Monday (April 17).

Followed two days later by its feathery sibling, both Humboldt Penguin chicks are now being hand-reared by keepers in the Zoo’s custom-built incubation room, after their parents were unable to care for them.

Covered in soft grey feathers, the tiny birds are weighed every morning and hand-fed three times a day by their keepers, and can be seen by visitors cozying up to a cuddly toy Penguin under the warming glow of a heat lamp.

ZSL’s Head of Birds, Adrian Walls, said, “While everyone was tucking into chocolate eggs over Easter, the first Penguin chick of the year was hatching at ZSL London Zoo. It was great timing!”

Keepers at ZSL London Zoo are taking turns looking after the youngsters, who aren’t shy about letting them know when they’re “peck-ish”.

“The chicks’ bodyweight increases by around 20 per cent every day, so they grow extremely quickly and are always eager for their next meal,” said Adrian. “They make sure we know it’s feeding time…they may be only weeks old but they’ve definitely perfected their squawks already.”

The feisty fish-lovers are being fed a special diet of blended fish, vitamins and minerals, referred to by ZSL London Zoo’s bird keepers as ‘penguin milkshake’. But as they grow bigger, they’ll also be given small portions of fresh fish to support their development.

The chicks are expected to stay in the incubation room until they reach 10-weeks-old, by which time they should have grown from around 70g at hatch to 3kg in weight.

They’ll then move into the Zoo’s specially-designed ‘penguin nursery’, which includes a shallow pool for their swimming lessons, before eventually being introduced to the other 70 Humboldt Penguins in the colony.

The Humboldt Penguin (Spheniscus humboldti), also known as the Chilean Penguin, Peruvian Penguin, or Patranca, is a South American species that breeds in coastal Chile and Peru. Its nearest relatives are the African Penguin, the Magellanic Penguin and the Galápagos Penguin. The Penguin is named after the cold water current it swims in, which is named after Alexander von Humboldt, an explorer.

Toronto Zoo Hatching a Plan to Save African Penguins

1_IMG_4077 (9)

Toronto Zoo is proud to announce the successful hatching of four African Penguin chicks!

The yet-to-be-named chicks will be viewable in their Indoor Viewing Area beginning Friday, April 14 from 11:00 am to 2:00 pm daily.

It was determined after hatching that three of the four chicks were female, which is good news for the North American zoo population, which is predominantly male. Male and female penguins look similar, so a DNA test was required to determine their sex.

A new breeding pair, Thandiwe and Matata, laid the first two chicks. The couple was recommended to breed by the Species Survival Plan (SSP), and although they bonded very quickly, they didn’t do well at incubating their eggs.

Their first egg was laid on January 5, 2017 and the Keeper team swiftly intervened and swapped the egg to be raised by surrogate parents Ziggy and DJ, who have been great penguin parents in the past. Thandiwe laid the second egg a few days later on January 8, 2017, and Keepers were initially delighted to see her sitting on the egg very tightly, however she had to sit on the egg for seven days in a row. In the wild, penguin parents trade off egg-sitting duties as they both need to hunt and drink, however, Matata was a first-time parent and did not participate in sitting on the egg. As a result, the second egg was also given to another set of surrogates and proven parents, Shaker and Flap.

The last two chicks hatched from eggs that were laid by another brand new SSP pair, Eldon and Chupa, who are viewed as genetically important. This pair got along very well, however, given their genetic importance, it was decided to also use surrogates for their first egg. In fact, since DJ and Ziggy were viewed as the most reliable parents, this egg replaced the first egg from the other pair, which in turn went to another proven pair: Squeak and Pedro. A few days later on January 25, 2017, Eldon laid a second egg, which was left with the new pair to raise on their own and they did a great job. Needless-to-say, managing penguin chicks is tricky business! The chicks hatched on February 12, February 15, February 27 and March 4, respectively.

Incubation by the parents occurs for just over a month, then the hatched chicks stay with their parents in the nest for another 3 weeks. By this point the chicks are large and mobile enough for the Penguin Keepers to hand-raise them.

Currently, Toronto Zoo Keepers are teaching the chicks to be hand-fed fish and to get on a scale for daily weigh-ins. Recently, the Keepers gave them their first swimming lesson. The Zoo’s hope is for them to be ready to “fledge” and join their colony at around 80 days.

The arrival of the four chicks signifies a great achievement for these new penguin parents and the Zoo’s African Savanna Wildlife Care staff. This breeding season the Zoo was able to reach 100% of their SSP pairing and breeding goals.

The Toronto Zoo penguins help draw attention to this imperiled species. Of the 18 penguin species around the world, the African Penguin (Spheniscus demersus) is one of the most endangered. They are officially classified as “Endangered” by the IUCN. The current population size in the wild for the African Penguin is less than half of what it was 40 years ago, which equals only about 3 generations for penguins. Factors still affecting their decline include lack of food (due to climate change and over-fishing), disease, predation, and pollution (mainly oil spills). Today, there are fewer than 20,000 breeding pairs left in South Africa.


Landmark Penguin Chick Hatches at Woodland Park

1_RS32573_2017_03_23 penguin chick #60-1-phi (1)

The 60th Humboldt Penguin has hatched at Woodland Park Zoo’s new penguin exhibit.

The Zoo’s first breeding season began in 2010, and the latest chick hatched on March 17. Although keepers don’t yet know the sex of the chick, a naming contest was organized.

The community has been invited to vote on one of the following Spanish names: Sesenta (means 60), Diamante (diamond = for 60th anniversary), and Amor (love). The poll began March 30 and voting concludes today, April 3. Vote through the end of today via the Zoo’s special facebook post: https://www.facebook.com/WoodlandParkZooSeattle/

The chick’s parents, 9-year-old dad, Mateo, and 4-year-old mom, Mini, have raised chicks with other mates but the new chick is the first offspring between the pair.

To date, a total of six chicks have been produced in the current breeding season, with a couple more chicks anticipated to hatch. All the chicks are off exhibit, in nesting burrows, where they are under the care of the parents. Staff minimizes intervention to allow the parents to raise their chicks and gain parental experience. To ensure the chicks are achieving growth milestones staff regularly weigh them as they develop.

Before new chicks reach fledging age and go outdoors on exhibit, they are removed from the nest so keepers can condition the birds to approach them for hand feeding and other animal care activities. Chicks also are given round-the-clock access to a shallow pool where they can swim in a more controlled and less crowded environment. New chicks join the colony in the outdoor exhibit sometime in early summer.

People do not usually think of penguins as a desert species. Unlike their ice and snow-dwelling Antarctic cousins, Humboldt Penguins (Spheniscus humboldti) inhabit hot, dry coastlines in Peru and Chile. They live on rocky mainland shores, especially near cliffs, or on coastal islands.

Humboldt Penguins have a body made to swim. Using their strong wings, they “fly” underwater, usually just below the surface, at speeds of up to 20 miles per hour. They steer with their feet and tail.

Classified as a “Vulnerable” species by the IUCN, approximately 30,000 to 40,000 Humboldt Penguins survive in their natural range.

Woodland Park Zoo is committed to conserving Humboldt Penguins by supporting the Humboldt Penguin Conservation Center at Punta San Juan, Peru*. They also help preserve the species by breeding the birds through the Species Survival Plan and by encouraging visitors to choose sustainable seafood options.

*Punta San Juan is home to 5,000 Humboldt Penguins, the largest colony in Peru.


Rockhopper Penguins Enjoy Playtime in a Playpen

1_IMG_9834

Two Rockhopper Penguin chicks recently went on display at Omaha’s Henry Doorly Zoo and Aquarium.

Visitors will notice that the chicks are currently in a ‘playpen’ in the Zoo’s Antarctic Penguin exhibit. The playpen gives the chicks an opportunity to acclimate to the other penguins and the exhibit. This time also allows its feathers to fully grow in as down feathers are not waterproof. The chicks will remain in the playpen for a few weeks or until all of their feathers are in. The sexes of the chicks have not yet been determined.

The fuzzy pair hatched on December 11 and December 13, 2016. They currently weigh 4.3 and 4.2 pounds. Full grown Rockhopper Penguins weigh between 4.4 and 5.9 pounds.

The two chicks were parent-reared in the Zoo’s penguin exhibit. The eggs were incubated on exhibit and hatched at 32-34 days. At 30 days of age, the chicks were taught to hand feed from keeper staff, and they are now eating whole fish, primarily capelin.

The penguins at Omaha’s Henry Doorly Zoo and Aquarium are Southern Rockhopper Penguins (Eudyptes chrysocome). They are found in subantarctic waters of the western Pacific and Indian Oceans, as well as around the southern coasts of South America. They are the smallest yellow-crested, black-and-white penguin in the genus Eudyptes.

Since 1998, 31 Rockhopper Penguins have hatched at Omaha. They are currently listed as “Vulnerable” on the IUCN Red List. This species is primarily affected by: fisheries, loss of habitat, and oil spills.

The Zoo has extended an invitation to the public to help name the chicks. The official entry box is located in front of the Antarctic Penguin display in the Scott Aquarium. Name submissions will be accepted at the location until Thursday, February 23. The chicks’ names will be selected by the keepers that care for them and will be announced on Wednesday, March 8 on the Zoo’s website and social media. The entrants of the winning names will receive a unique Omaha’s Henry Doorly Zoo and Aquarium gift basket. Both male and female names will be accepted.

Cheyenne Mountain Zoo Celebrates New Penguin Chick

1_DSC03754

Cheyenne Mountain Zoo recently celebrated the hatching of a healthy African Penguin chick on December 13.

When the new chick hatched, it weighed approximately 51 grams, or just shy of 2 ounces (about the same as two slices of bread). Thanks to successful care by its first-time parents, it has already grown to about 2.5 pounds, or 40 ounces, in just over a month. That means the chick has grown by 20 times its initial hatch weight in approximately 35 days.

“Even at just over 30 days old, it’s already pretty feisty,” said Patty Wallace, lead Aquatics animal keeper. “That’s a good sign, since it’s a natural defense mechanism for chicks in the wild.”

The chick is being cared for by its parents, Murphy and Joe, in an off-exhibit area for now and is not currently viewable to the public. Once the chick molts for the first time and grows its adult feathers, it will be safe for it to be socialized with the rest of the flock in the main exhibit. Until the adult feathers come in, the chick doesn’t have waterproof protection, so it needs to be kept away from the exhibit’s pool for safety.

Keepers named the chick “Penny”. Although they will not know the gender of the chick until DNA testing is conducted, this unisex name serves as a nod to Cheyenne Mountain Zoo’s founder, Spencer Penrose, and the fact that the Zoo considers the chick their “lucky Penny.”

Although the Zoo has had previous Penguin hatchlings, past chicks were, unfortunately, not viable past 10 days. However, the Zoo felt that it was still important to allow the birds to do what came naturally by laying eggs, and keepers saw the egg incubating experience as helpful to the adults in the flock.

Veterinarians and Penguin experts are not sure why the offspring have been unsuccessful until now. However, several theories trace back to the Zoo’s aging Hippo and Penguin exhibit that was built in 1959. The Zoo is currently working to address those concerns with a $10.4 million capital campaign called Making Waves, which will fund new state-of-the-art buildings for both Hippos and Penguins.
