Hummingbirds

Hello,
Today, we're talking about an amazing group of birds that are known for their colours and the speed they beat their wings. That's right: hummingbirds!

General

Hummingbirds live in North and South America. They are some of the smallest and most colourful birds in the world. There are about 330 different kinds.

Their name comes from the humming sound that their wings make. They eat nectar and insects using their long bills. Some species migrate during the winter.

Flight

The wings of a hummingbird beat so fast that the hummingbird can hover in one place and can fly forwards, backwards or sideways. Small hummingbirds beat their wings about 70-80 times per second. During courtship displays or when chasing rivals, their wings can beat up to 200 times per second.

Feeding

Hummingbirds eat the nectar from the insides of flowers. They hover in front of a flower and put their long and slender bills inside to suck up the nectar. This provides them with enough energy to power their fast-moving wings.

Nests

The eggs of a hummingbird are the size of a pea. They are laid in a small nest made of moss bark and leaves. These materials are held together by the silk from a spider’s web and blend in with their surroundings, which keeps the nest and eggs safe from predators.

I hope you enjoyed reading about these incredible animals!

The life of ... an alcon blue butterfly

Hi everyone, Today we are going to be looking into the life of an alcon blue butterfly (Phengaris alcon). After mating, the females lay their eggs on marsh gentian, a blue-coloured wildflower. The eggs can only be laid on these flowers, as this is what the newly hatched caterpillars will eat. Although in some alp regions, they can also be found on willow gentians, a close relative of the marsh gentian. Once the caterpillars have hatched from the eggs, their main predator and danger are the ants that swarm below. But high on their plant homes, the caterpillars are safe. However, this isn't where the alcon blue caterpillars are going to stay forever. Eventually, they drop down to the ground using silk strings. With no protection, they are soon dragged off by the ants. The most amazing part is, the alcon blue caterpillars give off the same scent and chemicals as the ant larvae. So the ants take the caterpillars back to their brood chamber, wher...

Ozone layer

Hi everyone, What even is ozone? And the ozone layer? Where does the hole in the ozone layer come from and what does it mean? Is it dangerous? What can be done? Often the ozone-talk can be complicated and confusing, keeping an overview is hard and understanding all the problems always difficult. Let us break it down a bit for you: What is the ozone layer? We'll start with the basics: The ozone layer is part of the stratosphere, which is the second layer of the Earth's atmosphere, between 10 and 50 km above the Earth's surface and made up of protective gases. One of these protective gases is ozone. There is not much ozone in the atmosphere, only 0.3 molecule of ozone per 1 million molecules of air. This is because ozone is chemically unstable and only forms when ultra violet radiation (UV light) hits oxygen and breaks the bonds between the atoms. It fact it is so unstable that even when it has formed, it breaks down again relatively quickly. This leads to ozone turning back ...

Some info, resources & solutions to the plastic crisis

Hello Everyone, Plastic was once a miracle material but now it is the enemy. And we are the last generations who can do anything about it. If we want future generations to experience the world in all its amazing beauty like we have: we have to make a difference. We have the power to change the world for the better or for the worst. There will always be people who don't care about the environment but we do and so we need to do what we think is right. So join the campaign and fight for a better future. For our planet to return to its natural way with incredible biodiversity and amazing ecosystems. We have to make a difference now because all around the world animals are suffocating, drowning, and dying because of humans. You may think it isn't your problem but ultimately you are human and humans make plastic. Honestly, I can't believe that it has gotten to this point. We just have to change something because there is obviously something we ...

Coral reefs

Hello! We would love to introduce you to the topic of coral reefs and especially coral reef bleaching, as it is a greatly ignored but certainly significant topic. Have fun! 5 coral reef facts 1. The Great Barrier Reef is the largest living structure on the planet and is 2300 km long! 2. Less than 0.1% of the world's ocean surface is covered in coral reefs. 3. At least 25% of all marine animals live there. 4. Coral reefs are often known as the rainforests of the ocean. 5. In 1 square kilometre of coral reef, up to 35 tons of fish can be 'produced'. The 5 biggest coral reefs in the world 1. Great Barrier Reef (near Australia) 2. Red Sea Coral Reef (near Egypt, Israel and Djibouti) 3. New Caledonia Reef (Pacific Ocean near New Caledonia) 4. The Mesoamerican Barrier Reef (near Mexico, Belize, Guatemala and Honduras) 5. Florida Reef (Atlantic Ocean/Gulf of Mexico near Florida) What is coral? Coral is actually made up of small anim...

10 Animals on the Edge of Extinction No. 10- The Javan Rhino

The Javan rhino is listed as the 1st animal on WWF’s list of the 10 world’s most endangered animals, and I for my part, had never heard of it! If you hadn’t either, we’re changing that now. A bit about the rhino’s lifestyle The Javan rhinos are now exclusively found on the island of Java in Indonesia, but were once found in vast regions of northeast india and Southeast Asia. They have a dark grey colour which looks almost black when wet, and their (often pink) skin folds look a bit like plated armor. Both males and females have lower incisors which resemble tusks that they use to fight. Males have one relatively short horn of about 25 cm (10 inches). Javan Rhinos live in tropical forests, marshy areas and in the thick bush. They are mainly browsers and eat over 100 plants species they find in the forest, weigh between 900 and 2300 kg (1984-5071 pounds) and are between 3 and 3.2 meters (10- 10.5 feet) long. How endangered are we talking? Javan rhinos are the most ...

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 ...

Animals 11-15 in our '50 incredible animals' series

Hello, We have another five amazing animals for you today. Enjoy! 11. Dhole This is a dog species which looks rather like a red fox . They are difficult to put into any of the dog subfamilies. They aren't foxes, nor wolves, nor domestic dogs. Dholes are fast runners and live in packs of 5-12 individuals. Although sometimes, different packs will join forces to become a pack of 30 or more individuals! However, these super packs are broken up after a successful hunt. The different packs rarely attack each other as neighbouring packs are often closely related. Dhole packs live in burrows with multiple entrances. They can be found in eastern and southern Asia. They eat wild berries, insects and lizards and as a pack hunt deer, rodents and other wild mammals. Interestingly, unlike other dogs, they rarely kill by biting at the throat. They are also good swimmers! 12. Irrawaddy dolphin The Irrawaddy dolphin can be found in coastal areas of south a...

How has the COVID-19 pandemic affected the environment?

Hello and welcome back to another post! The pandemic has affected us all in many ways but what about the environment. How has it been affected? Today we'll be going into that. How did it start? So COVID-19 broke out in late 2019 in China but how it started is still a greatly controversial topic. Prof Stephan Turner told The Guardian in an online article in April: [...] says what’s most likely is that virus originated in bats. However, how it transferred to humans still isn't 100% certain. Scientists mostly agree that it didn't come directly from a bat, but instead was transferred through another animal. Regardless of how it reached humans, the main idea is that it came from a live animal, either in a food market or in the meat industry . Either way, it was our mistreatment of animals that lead to this disastrous pandemic that has claimed the lives of over 6.5 million people! Emissions When many businesses, industries and...
