Why one baby king penguin is Sea Life's new social media star

<p>A baby king penguin at Sea Life Melbourne has become the aquarium's newest celebrity for one massive reason: his size. </p> <p>Pesto the king penguin is just nine months old and 22.5 kilogram, which is already bigger than his parents. </p> <p>Photos of Pesto, who is just 90 centimetres tall, towering over his parents have gone viral online, with thousands of people shocked at the animal's whopping size. </p> <p>When Pesto was born, he broke the record of being the biggest chick ever born at Sea Life. </p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-permalink="https://www.instagram.com/reel/C-Crh17SzVD/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/reel/C-Crh17SzVD/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Herald Sun (@heraldsunphoto)</a></p> </div> </blockquote> <p>"I think he's always going to be a big boy," says Sea Life penguin keeper Michaela Smale.

World famous gay penguin dies

<p>One half of the world famous gay penguin couple at Sydney's SEA LIFE Aquarium has died. </p> <p>In 2018, Gentoo penguin Sphen made international headlines when he coupled up with another male gentoo penguin, Magic.</p> <p>Shortly after meeting, the two male penguins began making a nest together out of pebbles ahead of breeding season, so the aquarium staff gave them a foster egg to care for.</p> <p>Sphen and Magic raised two foster chicks, Sphengic (Lara) in 2018 and Clancy in 2020, and are among the most strongly bonded gentoo penguin pairs at the aquarium.</p> <p>The penguins have inspired books, documentaries, new studies in the NSW syllabus and even featured on a float at the Sydney Mardi Gras parade. </p> <p>Earlier in August, Sphen passed away at the age of 12, which is considered a long life for a gentoo penguin. </p> <p>In order to help process the loss, the aquarium staff took Magic to see his partner's body to help with the understanding that Sphen would not be returning.</p> <p>He immediately started singing, which was reciprocated by the colony.</p> <p>"The loss of Sphen is heartbreaking to the penguin colony, the team and everyone who has been inspired or positively impacted by Sphen and Magic's story," SEA LIFE Sydney Aquarium's general manager, Richard Dilly, said in a statement.</p> <p>"Sphen and Magic's love story captivated the world and it's been an honour to welcome local and international fans, some of which travelled long distances to see them in real life."</p> <p>"The team's focus is now on Magic, who will soon prepare for his first breeding season without Sphen."</p> <p><em>Image credits: SEA LIFE Aquarium Sydney </em></p>

15 facts (and pictures!) that prove penguins are the world’s most adorable animals

<p>Every day is a good day to appreciate these tuxedo-wearing birds.</p> <p><strong>Nearly all penguins live in the southern hemisphere</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2022/11/01-can-penguins-Shutterstuck-770.jpg" alt="" width="700" height="454" /></strong></p> <p>Contrary to media representations of the North Pole, no penguins live up there. The 17 penguin species (some scientists say there are 20) are spread out between Antarctica, Argentina, Australia, Chile, New Zealand, and South Africa. The only exception is the Galapagos penguins, who live close to the equator on the Galapagos Islands and occasionally venture into northern hemisphere waters.</p> <p><strong>Penguins have been around for a long time</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2022/11/02-emperor-penguins-Shutterstock-770.jpg" alt="" width="700" height="454" /></strong></p> <p>An amateur fossil hunter discovered the bone of an extinct penguin ancestor, and scientists say it’s 61 million years old. That means it probably outlived the dinosaurs that went extinct 65.5 million years ago. Fossils also suggest that this prehistoric bird could fly and could grow up to 150 centimetres tall.</p> <p><strong>They eat a lot</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2022/11/03-penguin-eating-Shutterstock-770.jpg" alt="" width="700" height="454" /></strong></p> <p>Penguins are carnivores, and their diets consist of fish, krill, crabs, squid, and other sea creatures. According to Smithsonian Magazine, they can eat over one kilogram of food every day during summer months, but eat only a third of that during the winter.</p> <p><strong>They sneeze</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2022/11/04-sneeze-penguin-Shutterstock-770.jpg" alt="" width="700" height="454" /></strong></p> <p>Their sneezes serve an important purpose, though. Because they eat so much seafood, penguins also consume a lot of saltwater. To get rid of all that salt, their supraorbital glands above their eyes filter it out of the bloodstream, and then, the penguins excrete it through their bills or their sneezes.</p> <p><strong>The littlest penguin may be the cutest</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2022/11/05-little-penguin-wildlife-park-Shutterstock-770.jpg" alt="" width="700" height="454" /></strong></p> <p>Little blue penguins (also called fairy penguins) really are little. They only grow to be 33-38 centimetres tall, and adults only weigh one kilogram.</p> <p><strong>Emperor penguins are the largest species</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2022/11/06-emperor-penguins-sliding-Shutterstock-770.jpg" alt="" width="700" height="454" /></strong></p> <p>They’re around 120 centimetres feet tall and can weigh up to 40 kilograms.</p> <p><strong>Penguins are expert swimmers</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2022/11/07-swimming-penguin-Shutterstock-770.jpg" alt="" width="700" height="454" /></strong></p> <p>No, these adorable birds can’t fly. Instead, they use their wings to fly through the water (so to speak) at speeds up to 40 kilometres per hour.</p> <p><strong>They can’t help but waddle</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2022/11/08-gentoo-penguin-Shutterstock-770.jpg" alt="" width="700" height="454" /></strong></p> <p>Penguins’ bodies are shaped to easily glide through water, with a long body and short legs. So when they walk, the result is a clumsy-looking waddle. Penguins also get around on land by hopping and tobogganing, where they glide on their bellies and use their feet and wings to gain speed.</p> <p><strong>They spend most of their time in the water</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2022/11/09-gentoo-penguins-Shutterstock-770.jpg" alt="" width="700" height="454" /></strong></p> <p>According to Ocean Conservancy, penguins spend about 75 per cent of their lives in water. They go on land to mate, lay eggs, and raise their babies.</p> <p><strong>Speaking of penguin babies…</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2022/11/10-emperor-penguin-chicks-Shuttersetock-770.jpg" alt="" width="700" height="454" /></strong></p> <p>They’re called chicks or nestlings. They form little groups called crèches to look out for predators and keep each other warm while their parents look for food.</p> <p><strong>Penguins are romantic</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2022/11/11-shutterstock_516711187-Shutterstock-770.jpg" alt="" width="700" height="454" /></strong></p> <p>Some penguin species mate for life, like the macaroni penguin. These guys and gals show their affection by performing an ‘ecstatic display,’ in which they swing their heads back and forth and cackle loudly.</p> <p><strong>Birds of a feather mate together</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2022/11/12-king-penguins-Shutterstock-770.jpg" alt="" width="700" height="454" /></strong></p> <p>Most penguin species breed in large groups called colonies (only two species don’t) for protection. Those groups can range from a couple hundred to hundreds of thousands of penguins!</p> <p><strong>Daddy penguins keep their eggs warm</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2022/11/13-dad-penguins-incubate-eggs-Shutterstock-770.jpg" alt="" width="700" height="454" /></strong></p> <p>At least, male emperor penguins do, but not by sitting on them. These dads balance the eggs on their feet and cover them with feathered skin called a brood pouch. They stay like this for two months – without food and with no protection from the Antarctica weather – until the mums come back with food for the young ones. Talk about parents of the year!</p> <p><strong>Their feathers keep them camouflaged</strong></p> <p><strong><img src="https://oversixtydev.blob.core.windows.net/media/2022/11/14-king-penguins-1-Shutterstock-770.jpg" alt="" width="700" height="454" /></strong></p> <p>When penguins swim, their black backs keep them invisible from predators up above, and their white bellies blend into the bright sunlight coming through the waves. We bet your tuxedo can’t do that.</p> <p><strong>Feathers also keep them warm</strong></p> <p><img src="https://oversixtydev.blob.core.windows.net/media/2022/11/15-imperial-penguins-colony-Shutterstock-770.jpg" alt="" width="700" height="454" /></p> <p>Penguins don’t have blubber like other sea animals, but their many feathers serve the same purpose. (In particular, emperor penguins have 100 feathers per six square centimetres). The feathers trap a layer of warm air next to their skin, and their surface feathers get colder than the surrounding air to keep their bodies warm.</p> <p><em><span id="docs-internal-guid-d01c285d-7fff-1863-8624-cd52bd052f15">Written by Claire Nowak.

Why the penguins are out in record-breaking numbers

<p dir="ltr">Australia’s Phillip Island, home to the world’s smallest penguins, has been the site of a record-breaking “penguin parade”, with over 5,200 birds crossing the beach in a single night.</p> <p dir="ltr">Every day at dusk, some of these penguins make the trip to their nesting grounds on-shore after hunting for fish, squid, kill and small crustaceans in the ocean in an event that regularly draws large numbers of tourists.</p> <p dir="ltr">“Penguin viewing has occurred at the same location for over 50 years and the birds have been habituated to nightly activity over time,” Paula Wasiak, a Phillip Island Nature Parks field researcher, told <em><a href="https://www.livescience.com/record-breaking-penguin-parade-australia" target="_blank" rel="noopener">Live Science</a></em>.</p> <p dir="ltr">On May 3, 5,219 of the 40-centimetre-tall penguins stormed the beach toward their burrows in less than an hour.</p> <p dir="ltr">“We couldn’t believe our eyes when more than 5,000 penguins came out of the water in less than an hour,” Wasiak said in a <a href="https://www.penguins.org.au/about/media/latest-news/new-news-page-36/" target="_blank" rel="noopener">statement</a>.</p> <p dir="ltr">The penguin extravaganza comes just a week after the record for the island’s largest penguin parade was broken, when 4,592 penguins came ashore all at one on April 29 according to Wasiak.</p> <p dir="ltr">Overall, May has seen multiple parades with surprisingly high numbers, with 3,000 to 5,000 birds marching each night.</p> <p dir="ltr">“It’s been a penguin party night after night, which is unusual for this time of year, let alone in record numbers like we are seeing now,” Wasiak said.</p> <p dir="ltr">Historically, the larger parades tend to take place in November and December during peak breeding season, according to the Penguin Foundation.</p> <p dir="ltr">As for why they’re coming together in such large numbers lately, it might be to do with this year’s La Niña event.</p> <p dir="ltr">Little penguins primarily eat small fish, such as anchovies, which can only live in a narrow temperature range, according to Wasiak.</p> <p dir="ltr">“It suggests that during La Niña years, the ocean conditions around Phillip Island are often ideal for an abundant supply of fish/food close to shore,” she told Live Science.</p> <p dir="ltr">But, Wasiak said the turnout could also be related to another phenomenon called the “autumn breeding attempt”, where older penguins attempt to breed outside of mating season and results in more penguins heading out to forage, or improvements in the island’s habitat.</p> <p dir="ltr">“One of the main areas we’re seeing an increase in penguin attendance is to the east of the colony. In the past, poor habitat erosion in this area meant penguins had difficulty accessing and nesting there,” she explained.</p> <p dir="ltr">“A lot of work has gone into improving dune structure, creating penguin pathways and restoring habitat, which is now paying off.”</p> <p dir="ltr">If you can’t make it to the island for the nightly parades, you can also watch livestreams on <a href="https://www.facebook.com/phillipislandnatureparks" target="_blank" rel="noopener">Facebook</a> and <a href="https://www.youtube.com/user/pipenguinparade" target="_blank" rel="noopener">YouTube</a>.</p> <p><span id="docs-internal-guid-34818260-7fff-38dc-9520-442a4219e3ca"></span></p> <p dir="ltr"><em>Image: Phillip Island Nature Parks</em></p>

This is the most remote place on Earth

<p><span style="font-weight: 400;">One of the most remote places on Earth is covered in glaciers, mountains, and fjords.

Genetics reveal that Antarctica was once too cold for penguins

<p>Emperor penguins are truly remarkable birds – they thrive in the coldest environment on Earth and live year-round on the ice. Breeding colonies congregate on sea ice during the Antarctic winter and must withstand temperatures that regularly drop below -30C.</p> <p>In fact, emperor penguins are so adapted to cold conditions that they become heat stressed when temperatures climb above 0C. Emperor penguins are therefore particularly threatened by climate change, and their numbers are expected to <a href="http://www.nature.com/nclimate/journal/v4/n8/full/nclimate2280.html">decline</a> in the coming decades.</p> <p>However a <a href="http://dx.doi.org/10.1111/gcb.12882">new study</a>, published today in Global Change Biology, shows that it was once too cold even for emperor penguins.</p> <p><strong>Penguins past and present</strong></p> <p>In our study of how changing climate has affected emperor penguins over the past 30,000 years we found that, during the last ice age, emperor penguins were roughly seven times less common than today. What’s more, it appears that only three populations survived the last ice age. The Ross Sea was a refuge for one of these populations.</p> <p>In the first continental-scale genetic study of emperor penguins, we examined genetic diversity of penguins modern and ancient to find out how they’re related. We collected genetic samples from eight breeding colonies – no easy feat given that emperor penguins live in some of the remotest places on Earth in conditions that would send most people running for a roaring fire and a hot cup of tea.</p> <p><a href="https://images.theconversation.com/files/72856/original/image-20150224-32209-815vrd.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/72856/original/image-20150224-32209-815vrd.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="" /></a> <span class="caption">A rookery near Mawson station.</span> <span class="attribution"><span class="source">Chris Wilson/Australian Antarctic Division</span>, <span class="license">Author provided</span></span></p> <p>Reaching the colonies involved weeks on the notoriously wild Southern Ocean (and considerable seasickness), helicopter journeys over pristine expanses of sea ice, and long snow shoe and ski traverses. The “A” (for Antarctic) factor was a constant presence, with delays caused by heavy sea ice that trapped ships for days at a time and blizzards that grounded helicopters.</p> <p>Nevertheless, the effort paid off. Analyses of genetic data allowed us to reconstruct the population history of penguins, and correlate it with environmental conditions inferred from ice core data. The findings indicate that approximately 12,000 years ago, after the ice age ended and temperatures began to rise and sea ice around Antarctica decreased, emperor penguin numbers began to climb.</p> <p><strong>Goldilocks penguins</strong></p> <p>The emperor penguin’s relationship with sea ice can be described as a Goldilocks phenomenon.</p> <p>The penguins need stable sea ice to stand on during their breeding season. If the sea ice extent is too great then the journey between the colony and their feeding grounds in the ocean may prove too costly in terms of energy reserves.</p> <p>If there is too little sea ice or if the sea ice is not stable enough, then the penguins cannot establish successful breeding colonies. The duration of the sea ice season is also important – if the season is too short for the chicks to adequately mature, then they may not have time to grow their adult, waterproof feathers and will not survive at sea.</p> <p>During the last ice age there was about twice as much ice as there is today. Emperor penguins were probably unable to breed in more than a few locations around Antarctica. The distances from the open ocean, where the penguins feed, to the stable sea ice where they breed was probably too great in most of their modern breeding locations.</p> <p>The three populations that did manage to survive the ice age may have done so by breeding near polynyas – areas of ocean that are kept free of sea ice by wind and currents. One of the most important of these polynyas was located in the Ross Sea.</p> <p><strong>Uncertain future</strong></p> <p>Because of this Goldilocks relationship emperor penguins are facing an uncertain future.

“We’re losing our penguins”: Stricter penalties demanded after a spate of dog attacks

<p><span>Calls have been renewed to increase the penalties for the owners of dogs which injured other animals in Tasmania after a spate of attacks on little penguins.</span></p> <p><span>Last Thursday, an attack in Wynyard saw 42 little penguins being mauled to death, sparking community outrage and an investigation by the Parks and Wildlife Service.</span></p> <p><span>According to the <em><a href="https://www.abc.net.au/news/2019-09-04/penguins-numbers-in-tasmania-dip-after-dog-attack-spate/11473906?pfmredir=sm">ABC</a></em>, this is the seventh attack on little penguin colonies in the past year, with the death toll reaching more than 170. </span></p> <p><span>“It just seems that we barely forget about one dog attack and then there’s another one that happens almost straight away,” said Birdlife Tasmania convenor Eric Woehler.</span></p> <p><span>“The Tasmanian community clearly has had enough … [Yet] we don’t see any real response in terms of changes on the ground.”</span></p> <p><span>Wynyard Mayor Robby Walsh said he was devastated by the deaths, and that he could not do much aside from pushing for increased surveillance. </span></p> <p><span>“We need physical patrols from rangers and community groups,” Walsh said. </span></p> <p><span>“Whilst we want to help, we can’t interfere. It falls within the jurisdiction of the Department of Primary Industries, Parks, Water and Environment.</span></p> <p><span>“It’s a serious thing and I think the Parks and Wildlife need to work in some sort of assistance.”</span></p> <p><span>Walsh also ruled out the possibility of installing dog-proof fences. “Once they get a taste of them, they’ll be back... even an elephant fence wouldn’t stop them,” he said.</span></p> <p><span>“We can’t fence off the coast. The responsibility lies with the owners.”</span></p> <p><span>Penguin Rehab and Release president Kathy Grieveson said more solutions, such as clearer exclusionary zones and fines, should be considered to help protect penguin sanctuaries from dogs.</span></p> <p>“Every time we go down to the colony there are dog tracks all through them,” Grieveson told <em><a href="https://www.theadvocate.com.au/story/6357956/pet-owner-crackdown-on-the-cards-following-penguin-attack/">The Advocate</a></em>.  </p> <p>“If it means fining owners then... that seems to be the only thing that people take notice of – if it hits the back pocket.”</p> <p><span>Under the current Dog Control Act, the owner of a dog which attacks a person or an animal to cause minor injuries can be fined up to $650. Serious injuries may attract a fine of up to $2,600.</span></p> <p><span>Woehler said the penalty should be harsher. “Let’s make it about $1,000 as a starting point. We’re talking about $40,000 for what we’ve just seen on the last weekend,” he said. “We’re losing our penguins in Tasmania.”</span></p> <p><span>In June, the Tasmanian Government said it would review and strengthen the laws, with more rangers being deployed to the danger areas.</span></p>

How do penguins stay warm in the freezing cold waters of Antarctica?

<p><strong><em>How can penguins and polar bears stay warm in the freezing cold waters of Antarctica? - Riley, age 8, Clarksville, Tennessee USA.</em></strong></p> <p>Thanks for your question, Riley. The first thing I should probably say is that while a lot of people think polar bears and penguins live together, in fact they live at opposite ends of the Earth. Polar bears live in the northern hemisphere and penguins live in the southern hemisphere.</p> <p>I’m a penguin researcher so I’m going to explain here how penguins can stay warm in Antarctica.</p> <p>There are four species of penguins that live in Antarctica: emperors, gentoos, chinstraps, and Adélies.</p> <p>All these penguins have special adaptations to keep them warm, but emperor penguins might be the most extreme birds in the world. These amazing animals dive up to <a href="https://academic.oup.com/condor/article-abstract/97/2/536/5126161">500 metres</a> below the surface of the ocean to catch their prey, withstanding crushing pressures and water temperatures as low as <a href="https://nsidc.org/cryosphere/seaice/index.html">-1.8℃</a>.</p> <p>But their most incredible feat takes place not in the ocean, but on the sea ice above it.</p> <p><strong>Surviving on the ice</strong></p> <p>Emperor penguin chicks must hatch in spring so they can be ready to go to sea during the warmest time of year. For this timing to work, emperors gather in large groups on sea ice to begin their breeding in April, lay their eggs in May, and then the males protect the eggs for four months throughout the harsh Antarctic winter.</p> <p>It’s dark, windy, and cold. Air temperatures regularly fall below -30℃, and occasionally drop to -60℃ during blizzards. These temperatures could easily kill a human in minutes. But emperor penguins endure it, to give their chicks the best start in life.</p> <p><strong>A body “too big” for its head</strong></p> <p>Emperor penguins have four layers of overlapping feathers that provide excellent protection from wind, and thick layers of fat that trap heat inside the body.</p> <p>Have you ever noticed that an emperor penguin’s body looks too big for its head and feet? This is another adaptation to keep them warm.</p> <p>The first place that you feel cold is your hands and feet, because these parts are furthest from your main body and so lose heat easily.</p> <p>This is the same for penguins, so they have evolved a <a href="https://www.journals.uchicago.edu/doi/pdfplus/10.1086/653666">small beak</a>, small flippers, and small legs and feet, so that less heat can be lost from these areas.</p> <p>They also have specially arranged veins and arteries in these body parts, which helps recycle their body warmth. For example, in their <a href="https://onlinelibrary.wiley.com/doi/pdf/10.1111/j.1469-7998.1975.tb01398.x">nasal passages</a> (inside their noses), blood vessels are arranged so they can regain most of the heat that would be lost by breathing.</p> <p><strong>Huddle time</strong></p> <p>Male emperor penguins gather close together in big groups called “huddles” to minimise how much of their body surface is exposed to cold air while they are incubating eggs.</p> <p>This can cut heat loss in half and keep penguins’ core temperature at about <a href="https://www.physiology.org/doi/full/10.1152/ajpregu.00912.2005">37℃</a> even while the air outside the huddle is below -30℃.</p> <p>The biggest huddles ever observed had about 5,000 penguins! Penguins take turns to be on the outer edge of the huddle, protecting those on the inside from the wind.</p> <p>Incredibly, during this four-month period of egg incubation the male penguins don’t eat anything and must rely on their existing fat stores. This long fast would be impossible unless they worked together.</p> <p><strong>Changing habitats</strong></p> <p>Emperor penguins are uniquely adapted to their Antarctic home. As temperatures rise and sea ice disappears, emperors will face new challenges. If it becomes too warm they will get heat-stressed, and if the sea ice vanishes they will have nowhere to breed. Sadly, these incredible animals may <a href="https://www.nature.com/articles/nclimate2280">face extinction</a> in the future. The best thing we can do for emperor penguins is to <a href="https://theconversation.com/2040-hope-and-action-in-the-climate-crisis-117422">take action</a> on climate change now.</p> <p><em>Written by Jane Younger.

Scientists make huge discovery in penguin colony

<p>Australian, French and Japanese scientists <a href="http://www.oversixty.com.au/travel/cruising/2017/03/cruise-experiences-everyone-needs-to-have-once/"><span style="text-decoration: underline;"><strong>working in East Antarctica</strong></span></a> have made a huge discovery regarding the number of Adelie penguins in the region.  </p> <p>Working across a region around 5000km in size, scientists used surveys, tagging data and images to estimate there are around <a href="http://www.oversixty.com.au/news/news/2016/06/amputee-penguin-gets-new-prosthetic-foot/"><span style="text-decoration: underline;"><strong>six million birds</strong></span></a> in the area. Previous estimates had suggested there were only 3.6 million inhabiting the region.</p> <p>Seabird ecologist Dr Louise Emmerson said, “Non-breeding birds are harder to count because they are out foraging at sea, rather than nesting in colonies on land.</p> <p>“However, our study in East Antarctica, has shown that non-breeding Adélie penguins may be as, or more, abundant than the breeders.</p> <p>“These birds are an important reservoir of future breeders and estimating their numbers ensures we better understand the entire population’s foraging needs.”</p> <p>How cute?

Oddball, the Warrnambool penguin protector, has died aged 15

<p>One of Australia’s most famous – and hard-working – dogs ever, Oddball, the Maremma sheepdog employed to protect a penguin colony on Warrnambool’s Middle Island, has passed away at the age of 15 – or 105 in dog years.</p> <p>“Old Oddball has gone to the big chook run in the sky and will rest in peace,” the Middle Island Maremma Project posted on Facebook yesterday.</p> <p>Oddball was enlisted back in 2006 to protect the island’s fairy penguin colony from foxes, who had culled the population of the birds to less than 10 in 2005. While she only stayed on the island for three weeks before becoming lonely and swimming back to shore, her role as penguin protector inspired a new training program, teaching other Maremma dogs to follow in Oddball’s footsteps. And, in the ten years since the program began, the number of penguins has risen to an impressive 130. There are currently two dogs, Eudy and Tula, who spend five days a week during the penguins’ breeding season to protect the colony.</p> <p>For the last few years, Oddball has lived on her owner Allan “Swampy” Marsh’s farm in Dennington due to a heart condition which slowed her down. It was there where she peacefully passed away last week.</p> <p>Rest in peace, Oddball.</p> <p><strong>Related links:</strong></p> <p><a href="/news/news/2017/02/man-stops-traffic-to-help-a-swan-get-back-home/"><strong><em><span style="text-decoration: underline;">Man stops traffic to help a swan get back home</span></em></strong></a></p> <p><a href="/news/news/2017/02/distracted-beagle-steals-hearts-at-westminster-dog-show/"><span style="text-decoration: underline;"><em><strong>Adorably distracted beagle steals hearts at Westminster Dog Show</strong></em></span></a></p> <p><a href="/news/news/2017/02/students-raise-600-dollars-in-single-night-for-dogs-surgery/"><span style="text-decoration: underline;"><em><strong>Students raise $600 in a single night for dog’s surgery</strong></em></span></a></p>

Amputee penguin gets new prosthetic foot

<p>A penguin named Bagpipes had his foot amputated years ago after he was found back in 2007 with a fishing line wrapped around his leg.</p> <p>Bagpipes, who's currently under the care of the International Antarctic Centre, has been waddling around on his stump. Recently, his life changed for the better when he was fitted for a 3-D printed prosthetic foot.</p> <p>Senior lecturer at the University of Canterbury's mechanical engineering department Don Clucas, who is behind the prosthetic, designed and printed the prosthetic all for free.</p> <p>"It's designed to level him out a bit and make life a bit more comfortable for him," penguin keeper Mal Hackett said in an interview with Stuff.co.nz. “Hopefully the prosthetic will make Bagpipes' life a little easier.”</p> <p>Until now, the penguin, whose leg has been supported by foam beer bottle holders fitted around his foot, has experienced some trouble with infection. Now, the team at the centre is hoping that his new foot will alleviate his pain and help him learn how to walk and swim properly. Apparently, his trial run went “better than expected”.</p> <p>Watch the video above to see the heart-warming progress of little Bagpipes.</p> <p>Do you have an animal rescue story to share with us?
