Penguin encounters: Exhibit opens at Ripley's Aquarium, features 18 animals


GATLINBURG - It was a nose-to-beak Tuesday at Ripley's Aquarium of the Smokies as the attraction opened its $5 million Penguin Playhouse exhibit.

People stared at penguins.

Penguins - often just a step away - stared back.

The aquarium marked 10 years in Gatlinburg by officially opening the 4,000-square-foot permanent addition featuring African black-foot penguins. Located where the aquarium's Veranda Restaurant was, the natural habitat is the aquarium's biggest and most expensive change.

The 18 penguins living in the exhibit belong to the Species Survival Plan of the Association of Zoos and Aquariums, which oversees the animals' location and reproduction. Another dozen birds will join the exhibit in coming weeks.

Designed like a rocky beach, Penguin Playhouse encompasses a 30,000-gallon, 59-degree saltwater tank and multiple above-water and underwater views for visitors. A clear acrylic window in the aquarium floor allows visitors to watch the birds swim through an underwater tunnel between the indoor and outside sections of their home.

But the habitat also gives visitors willing to get on their hands and knees an in-exhibit advantage point. Two clear acrylic underwater tunnels are part of the habitat's indoor section. They bend up into an acrylic, above-water bubble that overlooks the penguin's fabricated rock bench.

On Tuesday the more children who crawled through the tunnel and up to the bubble, the more penguins congregated around the bubble to watch the humans. But no bird was still for long. The penguins glided through the water, circled manmade rocks and dived to the habitat's bottom.

"This is really a perfect fit," Aquarium General Manager Ryan DeSear said. "I guarantee you nobody will come out of there (the exhibit) that's not smiling."

A Satellite Census for Penguins

For Penguins, a Satellite Census

Biologists Count Hard-to-Find Birds With Photos Supplied by Intelligence Agency

[PENGUIN1] Minden
Emperor penguin colonies, like this one on Cape Roget, are widely spaced in Antarctica, making it difficult to conduct a census of the birds.

MCMURDO, Antarctica—Bird-watcher Philip Trathan is counting the emperor penguins here—from space.
In the first complete census of these well-known birds, the British wildlife ecologist and his colleagues are scanning high-resolution satellite photos of Antarctica for penguins, like military analysts searching for Iranian rocket sites. In fact, their precision imagery comes from the U.S. National Geospatial Intelligence Agency. The photos are part of the roughly $25 million of commercial satellite images the agency buys every month for use by the Central Intelligence Agency and the Defense Department.

Tracking Penguins in Antarctica from 400 Miles Up

3:32
Researchers are using satellite data to track penguins and seals across the coldest region on earth without disturbing them - and without leaving home. WSJ's Robert Lee Hotz reports.

"You can count individual birds," said Dr. Trathan, a penguin ecologist at the British Antarctic Survey, who is part of an international census team.

Their penguin census, which will be completed later this year, is the latest application of satellite mapping techniques that are transforming perceptions of Antarctica, where millions of square miles of ice blend into a wilderness of white, and only penguins are truly at home. In many ways, this shifting snowscape is as uncharted as the day explorers first sighted its mainland almost 200 years ago.

"Until last year, we had better maps of Mars than of Antarctica," said Paul Morin, director of the University of Minnesota's Antarctic Geospatial Information Center, which is funded by the U.S. National Science Foundation to use the unclassified intelligence imagery in science projects like the penguin survey. "We can now see one of the most inaccessible places on Earth, on demand," Mr. Morin said.

With the newest high-resolution imagery, researchers can detect anything on the continent larger than an end table. At that scale, a four-foot-tall, 90-pound emperor penguin is just large enough to show up in a single pixel. Dressed by nature in darkly formal feather-wear, an emperor penguin stands out in high contrast against the ice, even when viewed by a camera moving at four miles a second in an orbit 423 miles overhead.

Still, the emperor penguins complicate the count by huddling together for warmth. On an especially cold day, as many as 10 of them can cram together on a square meter of ice—a space slightly larger than a single pixel. "If you have so many pixels of penguins," said mapping expert Peter Fretwell at the British Antarctic Survey, "you have to decide how many penguins per pixel." Wildlife biologists estimate the count will turn up between 200,000 and 400,000 breeding pairs.

Living across the continent's 5.4 million square miles of polar ice, the emperor penguins are a bellwether that can help researchers detect subtle changes in climate and ocean conditions affecting all of Antarctica. Other penguin species wax and wane in response to changing regional winds, temperature trends and commercial fishing. But so far, no one knows how emperor penguins have responded to the changes, because there has been no easy way to find them all.

"Emperors are a really tricky species to get a handle on," said Dr. Trathan. "At the moment, nobody really knows how threatened emperor penguins really are."
It's no wonder. The birds make themselves at home in two of Earth's most inaccessible environments. No other bird dives deeper underwater, as far as 1,500 feet. No other creature breeds on the sea ice during Antarctica's winter darkness, when temperatures drop to 80 degrees below zero and winds top 100 mph.

Penguins Under Pressure

Robert Lee Hotz/The Wall Street Journal
An international team of scientists is researching how Adélie penguins in Antarctica are coping with rapidly changing ice conditions and commercial fishing.
For years, field biologists based here at the U.S. McMurdo Station have tracked meandering emperors, bobbing like off-balance bowling pins, as they slip, slide and belly-flop over ridges of wind-rippled snow.
They have stood on stepladders to count the birds in congested formations, and hung cameras from helium-filled balloons to record their numbers more reliably.

They have bugged penguins with radio transmitters and shadowed them by jet with airborne infrared sensors that could detect a birds' body heat at a distance. Such techniques proved too intrusive and expensive for a systematic census.

The new census is not the first time penguin watchers have tried satellites. By chance, researchers last year discovered they could detect vast stains of penguin excrement on the ice using older low-resolution satellite images. That revealed the locations of 38 emperor colonies, 10 of them never seen before, Dr. Trathan and his colleagues reported last June in the journal Global Ecology and Biogeography.

Still, they couldn't actually see any penguins until they gained access to the newest images, which the intelligence agency buys from commercial satellite operators DigitalGlobe Inc. in Longmont, Colo., and GeoEye Inc. in Dulles, Va..

Scientists hope the newest images will allow them to study emperor penguins without disturbing them—and without leaving their home laboratories.

"If you can do it from space," said Dr. Trathan, "you can do it from your desk."

Widowed emperor penguin moving to Taipei for mates

Widowed emperor penguin moving to Taipei for mates

TAIPEI, Taiwan -- The widowed emperor penguin in the National Museum of Marine Biology & Aquarium (NMOMBA) in Pingtung will be moved to Taipei Zoo at the end of March, so that the penguin can mate with other emperor penguins in the Taipei Zoo.
 NMOMBA originally had a pair of emperor penguins. Since the female penguin died two years ago, the male penguin became the zoo's sole emperor penguin and has been living with the other penguin species in the zoo.
In the mating season last year, seeing all the other penguins mating and laying eggs, the penguin found an egg-shaped stone and incubated it. People at the NMOMBA do not want the penguin to bear loneliness any longer. They have decided to send their only emperor penguin to the Taipei Zoo so that it can have some company.

Li Jan-Jung, spokesperson of NMOMBA, said since the female emperor penguin died, they had wanted to import another mate for the male penguin from Russia. After the H1N1 outbreak, however, there were many more restrictions on importing birds. Knowing that the Taipei Zoo is very experienced in penguins, and that they already have some emperor penguins, they have decided to move the penguin there.

The future offspring of the male emperor penguin will be divided by the two zoos. The first one will stay at Taipei Zoo, the second one will go to NMOMBA.

Emperor penguin is the tallest and heaviest of the living penguin species and is endemic to Antarctica. They are serially monogamous. They stay faithful to only one mate each year. After the females lay the eggs, they transfer the egg to the males for incubation for 64 consecutive days.

New Wichita Penguins

Penguin chicks debut at Wichita zoo

Associated Press - April 17, 2010 3:54 PM ET
WICHITA, Kan. (AP) - Sedgwick County Zoo officials are showing off the latest addition to their flock, a pair of Humboldt penguin chicks.
The birds, named Chick 1 and Chick 2, were shown off this past week to the media in Wichita. They are the first Humboldt penguins to be born at the zoo.
There are 14 adult penguins at the zoo's Cessna Penguin Cove in addition to the two chicks. Within a few weeks, there is a chance that two more penguins may hatch.
Sedgwick County Zoo officials have been planning for the new arrivals for two years, determining which adult pair was best suited for parenthood.
The chicks hatched within days of each other in late March.

Sedgwick County Zoo welcomes two Humboldt chicks

BY BECCY TANNER»


If you go: World Penguin Day
  • When: 10 a.m. to 4 p.m. April 24
  • Where: Sedgwick County Zoo, 5555 W. Zoo Blvd.
  • What: Activities celebrating World Penguin Day, including keeper chats for zoo visitors interested in learning more about the penguins.
  • For more information, go to www.scz.org
For now, they are known as Chick 1 and Chick 2. If all goes well, they may soon be joined by Chick 3 and Chick 4. Chick 1 and Chick 2 are the first Humboldt penguins hatched at the Sedgwick County Zoo.
On Thursday, during their media debut, the two chicks refused to come out for the cameras, standing firmly behind Mom and Dad, offering only downy, shadowy glimpses of themselves.
"There is a lot of drama in our penguins," said Joe Barkowski, the zoo's curator of birds.
The zoo's Cessna Penguin Cove currently has 14 adult penguins — plus the two babies. Within a few weeks, there is a strong possibility two more penguins may hatch, Barkowski said.
Sedgwick County Zoo participates with other zoos in species survival plans, which are monitored by the Association of Zoos and Aquariums.
Sedgwick County Zoo officials began planning more than a year ago which penguin parents would be the most suitable to reproduce.
"The SSPs give us guidance on genetic and demographic pairings and which are the best to breed," Barkowski said.
One pair of the zoo's penguins who mated this winter were placed low on the reproduction priority list.
"Their offspring wouldn't be beneficial to the species' survival," Barkowski said.
So, their eggs were taken from them and replaced with fake eggs.
Another couple of penguins placed high in desirability, he said. One of their eggs was given to the first couple to raise.
"We were hedging our bets that they would each hatch one and put all their energy into one chick to increase the survivability of both chicks," he said.
On March 21, Chick 1 was hatched. But the foster parents didn't know what to do.
"Both pairs of penguins had never raised chicks before," Barkowski said. "Mom and Dad just didn't get it. They were protective. They incubated. They did everything right. They just were not giving the chick enough food."
So, zoo staff stepped in and gave the tiny chick enough food to keep it strong and active. Within a few days, Mom and Dad became more confident in their parenting.
In the meantime, Chick 2 hatched. From its birth, it ate and ate and ate.
The two chicks now weigh about 2 1/2 pounds. When fully grown, they will weigh closer to 8 pounds.
Barkowski said that as the chicks mature, they will begin to explore the exhibit and the public should be able to catch more glimpses of them.
The public may notice that none of the adult penguins are swimming much in their pool, he said. That's because they are nesting.
The adult penguins will occasionally come and take dips in the pool — and with them, perhaps there will be a sighting of a baby penguin.

Adoptive Parents Save Endangered Penguin Chick

Adoptive Parents Save Endangered Penguin Chick

Quick thinking and action by staff at Denver Zoo and Pueblo Zoo probably saved the life of an African penguin chick. On March 20, four days past its due date, the chick was assisted with emerging from its shell by Pueblo Zoo Animal Care Coordinator Melanie Pococke. Pococke then sought help from Denver Zoo staff in caring for the tiny bird, when the hatchling’s biological parents at Pueblo Zoo were unable to care for it.

Zookeepers from each zoo met halfway to bring the chick to Denver Zoo where it was placed under the care of experienced parents. The chick’s surrogate father, Durban, and mother, Spencer, are now taking excellent care of their adopted youngster.

Zookeepers always prefer animals are raised by their parents or surrogates of the same species. This helps ensure they have the skills to raise their own young. Upon receiving the chick, Durban and Spencer immediately began “brooding” the chick by covering it with their bodies and wings for protection and quickly began feeding it. Penguinchick_gh_7084l

“It has been a great collaboration. We are fortunate to have such a strong network of experienced bird caretakers within our Colorado Zoos,” says Pococke, who has been involved with raising 47 penguin chicks in her 20-year career at the Pueblo Zoo.

“We had to act quickly in order for this to be a success,” says Area Supervisor of Birds Mary Jo Willis. “We’re so pleased to be able to help Pueblo Zoo on this project. We’re thrilled that the surrogate parents took to the chick so quickly.”

The chick will continue to be brooded and fed by the surrogate parents for about 3 months while the chick is covered in soft insulating feathers.  During this time it is not visible to the public. Even in the wild, newly hatched penguins chicks don’t venture near water because they are covered with soft, downy feathers that provide good insulation on land, but would get soaked in the water. Eventually, though young penguins molt and grow in stiffer water repellant plumage.

African penguins are found in southern Africa. Although most people associate penguins with frigid temperatures, African penguins enjoy warmer weather. Even they have their limits, though. In the wild are mostly crepuscular – meaning, they are most active at dawn and dusk when temperatures are more comfortable in their warm weather climate.

They grow to more than two-feet-tall and can weigh around 10 pounds. Their black and white patterns are unique to each penguin, like fingerprints on humans. More important, though the patterns serve as camouflage from predators in the wild as they are swimming. Seen from above, their dark backs blend in with the water. Seen from below, their white bellies blend in with the sky above.

The African penguin is listed as vulnerable by the International Union for the Conservation of Nature and Natural Resources (IUCN). They nearly faced extinction because their eggs were harvested for food and their droppings, guano, are an important burrowing material, but is often used by humans for fertilizer.

They have also been subjected to oil spills from tankers rounding the South African coastline, which have wiped out entire colonies of this species. In the past, Denver Zoo has sent staff to Cape Town, South Africa to assist with a world wide effort following the “Treasure” oil spill that affected over 40,000 penguins in 2000. Staff helped rehabilitate penguins by cleaning oil off their bodies and monitoring their health through lab and blood work. Of the penguins brought in for rehabilitation more than 95 percent were saved!

Penguin couple adopt baby African penguin born at another zoo

Cooperation between two zoos in Colorado has helped save a newborn African penguin, a species that is classified as "vulnerable" to a high risk of extinction in the wild, according to the International Union for Conservation of Nature and Natural Resources (IUCN).
On March 20 at the Pueblo Zoo, the African penguin chick finally emerged from its shell -- four days past its due date, reports the Denver Post. When the tiny bird's biological parents couldn't care for it, Pueblo Zoo Animal Care Coordinator Melanie Pococke contacted the Denver Zoo.
"Zookeepers from each zoo met halfway to bring the chick to Denver Zoo where it was placed under the care of experienced parents," says the Denver Zoo in a statement. "The chick’s surrogate father, Durban, and mother, Spencer, are now taking excellent care of their adopted youngster."
The adoptive parents immediately began caring for the newborn by “brooding” the chick by covering it with their bodies and wings for protection and quickly began feeding it, says the Denver Zoo.
The chick will stay out of the public eye for the next three months as it "continues to be brooded and fed by the surrogate parents while the chick is covered in soft insulating feathers," according to the Denver Zoo. "Even in the wild, newly hatched penguins chicks don’t venture near water because they are covered with soft, downy feathers that provide good insulation on land, but would get soaked in the water," states the Denver Zoo. "Eventually, though young penguins molt and grow in stiffer water-repellent plumage."
In the wild, African penguins can be found in their native habitat, described as "24 islands and three mainland sites between Hollamsbird Island, Namibia, and Bird Island, Algoa Bay, South Africa," according to IUCN.
Over the last century, the population of wild African penguins have plummeted and is now 10% of what it used to be at the beginning of the 20th century, states the IUCN. "In the late 1970s, the population was estimated at 222,000 adults," states the IUCN. As of 2007, that number has dwindled to 72,000, and will continue decreasing at a rate of 17 to 51% over the next 20 years if there is no continuing rehabilitation, says the IUCN.
What's to account for African penguin's sharp decline in the wild? "Harvesting of eggs, reduction in the penguin’s food, removal of guano used by the penguins for burrowing sites and oil pollution from oil tankers," states the Denver Zoo.
Two oil spills in 1994 and 2000 are blamed for the killing of 30,000 African penguins. "Mortality from oilspills is serious and may increase if proposed development of harbours close to [African penguin] colonies proceeds," states the IUCN. "Most of the population is confined to just two areas, both near to major shipping ports."
African penguins are black and white in color, as are most penguins, but are distinguished by the pattern of their coloring, described as "a white stripe encircling a black cheek and throat and a black horseshoe-shaped stripe across the chest," as well as "featherless pink areas around their eyes."
They are also known as the Black-Footed Penguin, or more colorfully, as the Jackass Penguin because they make "donkey-like braying" noises during courtship
