10 Animals on the edge of extinction - you did not know about No.2

The Kākāpō ~ New Zealand's green teddy bear-parrot

The Kakapo is a bird mainly found in New Zealand. It is a rather curious creature, a pretty big, green, nocturnal parrot that cannot fly and looks like a mixture of a parrot, a penguin, an owl and a teddy bear. Kakapos are on the verge of extinction due to their peculiar breeding habits, predators, and hunters. They are flightless and nocturnal and are the biggest parrots in the world. They can also live for up to 120 years!

History

Like most living creatures, the number of Kakapos in New Zealand was healthy before humans arrived. They waddled across the islands like nothing else. However, when people came to New Zealand, they started hunting the Kakapo for its feathers, meat and skin. They also brought alien species such as rats, weasels or cats that posed a threat to which they were not accustomed to. Their survival "trick" (not really a new thing, maybe the Kakapos like it old-fashioned) is to freeze when they are in proximity to a predator, using their green plumage as camouflage. Their population decreased significantly, leaving them teetering on the brink of extinction. By 1995 only 51 Kakapos were left!

Diet

Kakapos are mainly herbivores (plant-eaters). They will feed on anything from fern roots and young shoots to fungi and fruit. But sometimes, they will also prey on bugs, larvae and even small reptiles! This varies depending on the time of year. For some reason, Kakapos are very keen on a specific fruit that grows on the rimu tree, a tree native to New Zealand. In fact, they love it so much that when the fruit is available, they won't eat anything else! So, I suppose it's a bit like chocolate!

Social structure and mating habits

Kakapos are solitary and territorial. They will only meet for mating. The males fight to attract a female, by making what is described as "booming" sounds. I listened to some recordings and would disagree with the naming, so feel free to make up your own opinion about it. After mating, the female leaves and the male continues trying to attract another mate. The female returns to her own territory and raises the chicks on her own in a kind of cave she digs underground. Interestingly, kakapos only breed during years when special trees called Pink Pine or Rimu bear a lot of fruit, however, they only bear fruits every 4-6 years! They do that as the fruit of these trees are full of nutrients that are essential for raising healthy chicks, but it results in a very slow increase of Kakapo numbers.


Kakapos are classified as critically endangered, however, their population is rising due to the Kakapo recovery programme that has been running since 1995. Scientists, rangers and volunteers have been working together, moving the Kakapos to predator-free islands, feeding them with nutrients so they breed more and supervising and checking on them. The population is increasing, however, it is a slow process. Recently, scientists sequenced their genomes so as to identify sequences that could lead to higher disease raites or chick mortality.

We hope you enjoyed this post - see you on Sunday!

The limits of the Earth - the planetary boundary model

Hi everyone, So today we're talking about a model that was introduced in 2009 and has offered a new perspective to thinking about environmental issues. The planetary boundary model has 9 boundaries, each has a safe zone. Once the safe zone is exceeded, the stable conditions on our planet are considered at risk, and there can be severe and possibly irreversible changes. The nine boundaries are considered separate however, they greatly affect each other. Novel Entities describes the introduction and accumulation of man-made novel chemical compounds. These include pesticides, nuclear waste and microplastics. Stratospheric Ozone Depletion refers to the depletion of the ozone layer which was a major problem in the 90s. Atmospheric Aerosol Loading is air particle pollution.  Ocean Acidification is self-explanatory. The boundary Biochemical Flows is composed of two separate boundaries; nitrogen and phosphorus. Both of the ele...

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...

Discussion || Should Everyone Switch To Electric Cars?

Hi Everyone! Thank you so much for joining me today, as I hop on the blog to discuss whether everyone switching to electric cars would really help the environment. In other words, should everyone switch to electric cars? This is the first part of a two-part series, discussing electric cars, so stay tuned for part two!! I would like to start this post by stating that I am by no means an expert. This is knowledge I have from my own experience, and from research I have done. If anything is incorrect please take it as it is and accept that this is a discussion and I am taking on board all opinions from reliable sources on this complex topic. Electric cars are a huge topic when it comes to sustainability and "saving our planet". There is no debating the fact that electric cars are better for the environment than diesel or petrol once they are on the road. But the production of them is often very polluting, with one study show...

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...

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 ...

July 2021 Factfile - some news from the past month, animals and plants!

Hi Everyone, July is over and August is here. This month we've divided the 'News' section into 'Good news' and 'Bad news'. This will hopefully make the post more structured and easier to navigate. News Good news: Pandas classified as vulnerable Giants pandas are now classified as vulnerable according to Chinese officials. They were originally classed as endangered , but now that numbers in the wild have gone over 1 800 they have been reclassified. This is due to hard conservation work in China and funds from volunteers all over the globe. However, they are still vulnerable so it is important that the good work continues. For all those who have supported giant pandas through websites or those who work actively with them: keep up the good work!    First baby beaver born on Exmoor in 400 years A baby beaver has been born on Exmoor, England, for the first time in 400 years! This is due to ...

Ecotourism: what it is, the advantages and the disadvantages

Hi Everyone! Today we wanted to talk about the idea of ecotourism, including the advantages and disadvantages of this concept. If you are looking to reduce your environmental and social impact when travelling, then this is the post for you! Ecotourism is a form of tourism which limits the damage to the environment and local community. It can involve helping in community projects such as planting trees, as well as taking part in local customs and festivals. It helps to keep the local culture alive, while preserving the natural environment.  The advantages are abundant. By helping in a project conserving the environment, tourists gain a new understanding and appreciation for the natural world and may be inspired to make changes in their "real" life to live more sustainably. It provides a valuable insight to a country and community, perhaps also inspiring more respect for different people and the lives they lead. The projects also provide sustainable income sources for locals, h...

Wildfires

Welcome back to Green World, In the last few months, wildfires have been raging across the globe. Hawaii, Canada, the USA, Spain, Portugal, Italy, Greece, Tunisia and countless more have been affected. But what are the environmental impacts of such a blaze? The USA has had an average of over 70 000 wildfires a year since 2000. In 2020, Californian wildfires emitted more than 90 million metric tons of carbon dioxide, which is more than the state's power industry emits per year. It is estimated that humans start 87% of wildfires. Around the world, 4 million squ. km are hit by wildfires every single year. This emits vast amounts of carbon dioxide, which fuels climate change . The smoke causes air pollution in the entire surrounding area and can lead to respiratory problems in humans. The air pollution also kills birds, including those migrating through the area. Studies also show that socially vulnerable populations are more at risk of harm...

19.07.2020: Animal of the week: Honey Bees

Hi everyone, This week's animal is the honey bee. Enjoy! General Information An average honeybee hive is made up of one queen, hundreds of male drones and thousands of female workers. If the queen bee dies then a new queen is created. The workers select a young larva and feed it with a special food called ‘royal jelly’. The ‘royal jelly’ makes the larva grow into a fertile queen. Queens live for several years but the workers only live for five or six weeks. An average worker will make a twelfth of a tee spoon of honey during her entire life. Drones are turned out of the hive and left to die in Autumn. In the summer months, the queen bee is very busy, she can lay up to 2500 eggs in a single day. How they affect the world around them Honey bees are very important for flowers, fruit and vegetables. This comes from the fact that they are pollinators. They help the plants by transferring pollen between male and female parts, meaning the plants can g...

Coral reefs
