The life of ... an emperor penguin

Hello,

Today, we're looking at the fascinating lives of emperor penguins. These incredible creatures have adapted to survive in the extreme conditions of Antarctica, and in this post, we'll explore their incredible lives.

In late May to early June just before the Antarctic winter sets in, female emperor penguins lay a single egg. They then leave the colony and go on a two month hunt. The male rests the egg on his feet and covers it with warm, feathered skin called the brood pouch. He will eat nothing for these two months. The chick hatches in August and the female returned to take over. She has spent two months feeding and now regurgitates some food for the newly-hatched chick. The male leaves to feed himself as he has been living off his fat reserves for the past two months.

The female keeps the chick in her brood pouch until the sea ice close to the breeding site breaks up as the temperatures warm. The chick is now strong enough to learn how to swim and hunt for themselves. They will return in 5 years to rear their own chicks. Interestingly, 15% of adults will find the same partner from the previous year. We don't know how they recognise them, because there isn't a permanant nest or specific place for them to return to.

Emperor penguins survive the chilling Antarctic winds by standing close together in huddles. They take it in turns to be in the middle before moving back to the outside to allow another individual to warm up. Emperor penguins are amazing swimmers. In fact, they are the deepest-diving birds in the world, reaching depths of over 500m and staying under water for over 20 minutes. They feed on squid, krill and fish.

Emperors are classified as near threatened however, they face a couple of threats. They are eaten by orcas and leopard seals. However a much bigger and long term threat is climate change. As with most species in the Antarctic, climate change is a massive problem. Most of the food chain in Antarctica, relies on the sea ice. The sea ice that is now being rapidly reduced. Just this week, an article in ScienceDaily came out warning about a "Catastrophic Breeding Failure in Emperor Penguins", due to the loss of sea ice. Warmer water temperatures cause problems in fish migration and could lead to thousands of chicks starving each year or the females being too weak to produce eggs that actually have a chance to survive. So, as with all animals, humans are pushing a pretty stable and well adapted population ever closer to extinction.

November Top Tips | sustainable activities and hobbies

Hello everyone, So this week, we are going to be talking about sustainable free time activities. This area can quite big when it comes to environmental impact, so here are some things that you can do in your free time, that are more sustainable. 1. Reading So reading is one of our favourite things to do. However, books are made of paper and the paper industry isn't great. Some ways you can get around this is by reading online (for example, on a kindle), or through borrowing books from a library or using book boxes. If there aren't any in your area then at least try to support independent bookshops! 2. Running If you love being active then this one is for you. Running is probably one of the most sustainable forms of sport. All you need are some running shoes and somewhere to run. There is obviously more high-tech gear but that isn't really necessary if it's just a hobby. 3. Gardening If you've got a small area of land o...

16.08.2020 Animal of the week: Elephant

Hello. On the 12th of August it was International Elephant Day, so we decided that this week's post should be about elephants. Elephants are the largest living land mammals. There are three types of elephant; the African bush elephant; the African forest elephant and the Asian elephant. African elephants have larger ears, whereas Asian elephants have smaller ears. Elephants use their trunks to breath, bring food and drink to their mouths and to grasp objects. Elephants' legs are like pillars. They carry the Elephant's massive weight. African bush elephants weigh 6000kg, Asian elephants weigh 4000kg and African forest elephants weigh 2700kg. Basically, they are very heavy.Elephants eat grasses, small plants, bushes, fruit, twigs, tree bark, and roots. Elephants can live up to 70 years old in the wild. They communicate by sight, touch and smell. Sadly, these wonderful mammals are in danger. African elephants are listed as vulne...

The life of ... a koala

Hello everyone, Today we're talking about koalas. Also known as koala bears, koalas are marsupials. So they're actually not bears. Koalas, phascolarctos cinereus , are tree dwelling and probably best known for spending most of the day sleeping. They live for up to 15 years in the wild although captive koalas generally live for longer. Koalas have a stout, gray body and a cream-coloured chest. They have a broad face, small yellow eyes and big fluffy ears. In adaptation to climbing, their feet are strong and clawed. Adult individuals in South Australia weigh 14kg and are 60-84cm big. Their Eastern cousins are considerably smaller. Koalas are found in Eastern and Southern Australia, where they live in eucalyptus trees. They feed on the leaves of these eucalyptus trees, eating up to 1.3kg a day. With a body weight of up to 14kg, this means they eat just under 10% of their body weight every single day. However, the le...

I can't wait to see what 2024 brings us. Fr...

Maldives - the direct impacts of climate change

Welcome back, Today we’re looking at the direct impacts of the climate crisis . The main reason why people don’t believe in climate change is that they can’t see it with their own eyes. So, we’re going to have a look at the Maldives where the effects of climate change become more obvious with every passing year. Maldives The full name of the Maldives is The Republic of the Maldives. It is an independent country made up of about 1 200 islands in the North Indian Ocean. The northernmost island is situated 370 miles away from the mainland (India). The islands are actually the tips of an ancient volcanic mountain range that is now almost completely submerged. In fact, the highest point is 1.8m-2.4m above sea level with the average elevation being 1m above sea level. The islands have a large tourism industry, due to the stunning nature found on and around the islands. 500 000 - 1 500 000 tourists visit the islands each year. This is mainly 'nature to...

August 2021 Factfile - some news, animals and a plant

Welcome to our August factfile, News Bad news :( Fires in and around Athens Athens has been under siege this month, but not by any army. The forests all around the capital and in other parts of Greece and Turkey have gone up in flames. Houses have been destroyed and thousands have been evacuated. The reason is, of course, climate change . “It’s been crazy over here. Between the extreme heat and the wildfires, it feels apocalyptic,” Eleni Myrivili wrote in an email on Thursday as the army was deployed to assist firefighters. “Ash is raining down on us here in Athens.” England's lake district in peril Lake District, a popular holiday resort in the north of England, is now eroding faster as a result of climate change and an increased amount of walkers due to the pandemic. Paths that were once two meters wide are now at least 12 meters wide on some walks. Also visitors tend to walk off the path, endangering local wildlife. With...

January 2021 Factfile - a bit of news from the past month and more!

Hi Everyone! Welcome to the first monthly fact file! We are going to share a news article from last month as well as animals and more! News You might have heard that the UK has authorised the use of a pesticide harmful to bees. It has been authorised for use on sugar beet with their excuse being to do with the virus yellows disease. But bees are in serious decline and this is not going to help. It is authorised for emergency use and only in specific conditions but, in our eyes, that doesn't make it okay. Farmers need bees to pollinate crops and now they are killing them with a horrible pesticide. What do you think? We would love your opinions below! For more information on bees in our honey bee post click here . We have also found an article about some Indonesian monkeys from the island of Bali who steal anything expensive, that tourists have because they know they will get a reward! They know which items have the most value and wi...

Pollination

Hello everyone, Today we're talking about pollination and its importance in the world's ecosystems. First a bit of basic plant biology. To reproduce most plants do have a differentiation into male and female, but not in the same way that we see in mammals. Both male and female reproductive organs can be found on the same plant, although not in the same place. Male gametes are produced in the stamens and are then found in pollen. On the other hand, female reproductive organs are called pistils and egg cells are found in the ovule (normally in the flower heads). Pollination describes the process of transporting the pollen to the egg cells, making it an essential part of the reproduction of plants. Nearly all seed plants worldwide require pollination to reproduce. Cone bearing trees also need pollination. Pollination is almost always assisted by other organisms such as insects, birds and mammals to transport the pollen. In some species wind ...

June Top Tips | Fast Fashion and Consumerism

Happy June everyone! This month you'll get introduced to the topic of fast fashion. It is a big thing, not only because of environmental reasons but also touches on topics such as child labour and exploitation. We know this sounds pretty grave once again, but here is some good news (surprise, surprise!): You can do something! Read on to learn about what fast fashion is, where the problems are and what you can do better. 1) What is fast fashion?! Fast fashion is a term for the ever-changing demand and supply loop of the clothing industry. Every season people want to wear different things, and different clothes are in style. That leads to people buying clothes, wearing them as long as everyone else thinks they're great and then jumping to the next wave of clothes. The demand of the masses changes quickly and the clothing industry has to react just a step ahead of them to make money. The goal is to produce the wanted clothes as quickly, as chea...

Evolution

Hi, So today, I am going to talk about evolution. We have mentioned this before in our Galapagos Ecosystem series but we’ve never gone over exactly what it is. So before Charles Darwin thought of his theory of evolution, the majority of people in Europe thought that all species were unrelated and that humans were not related to animals. This was mostly based on Christianity. Darwin studied hundreds of different species and on the Galápagos Islands , he first started to form his theory of evolution. Darwin's theory of evolution by natural selection, as it was later called, is best explained by the example of the giraffe. Let's assume that giraffes have short necks (as they did many centuries ago). Now a mother has two children. By chance, one has a slightly longer neck. This is a coincidence. As the giraffes feed on the lower leaves of the trees, these slower disappear. There aren't enough leaves for the giraffes. Thus the giraffe wi...
