Feathers can keep warm, waterproof, help birds fly, and have colorful hues How many interesting secrets does Little Feather still hold? Let's learn about it together today Get to know feathers Feathers, for birds, are not as simple as beautiful outerwear. They are important tools for maintaining body temperature, protecting the body, and communicating. Of course, the most important thing is still flying. Bird feathers can be divided into the following three categories based on their structure and function: The first type of feather: This is a large feather that covers the body of a bird, consisting of a feather shaft and feathers. The shape of the feathers is relatively large, with a hard and straight texture. They are the main flight feathers of birds and also serve as protective and thermal insulation. They are arranged closely, especially on bird wings, overlapping to provide the necessary lift and stability during flight. The second type of down feathers: down feathers, also known as golden feathers, are born below the main feathers and are most abundant in the chest and abdomen. Their feather axis is short, the feather branches are soft, clustered at the top of the feather axis, and the feather small branches are slender and do not have small hooks, and do not form feathers. The main function of feathers is to keep warm and protect the body. They are soft and slender, which can effectively lock in body temperature and maintain the stability of bird body temperature. The third type of feather: The feather shaft of the feather is…

Birds are one of the most widely distributed and vibrant animal groups in nature. Nowadays, the number of existing bird species in the world is still increasing, with over 10000 species living with us on this beautiful planet. Birds exhibit incredible diversity in behavior and appearance. Novelist Jonathan Franzen once said, "If you can see every bird in the world, then you will see the whole world" Geospiza difficilis When hunting, birds can be hunters, gatherers, or scavengers. The food of different birds varies: nectar, fruits, seeds, insects, amphibians, fish, small reptiles, mammals, other birds, carcasses, and even blood. The wide range of bird recipes is astonishing. Birds are masters of flight: some birds migrate thousands of miles every year: the Arctic Tern is the most migratory animal on Earth. According to a team of scientists, the migration distance of the Arctic Tern from the Farne Islands in Northumberland, UK is the longest in the world, from its breeding grounds to Antarctica and back, which takes 59650 miles, more than twice the circumference of the Earth. Some birds, such as ostriches and penguins, have completely lost their ability to fly. The rich diversity of birds makes them play a very important role in ecosystems. In many ecological evaluation projects, the number, species, and stability of birds in the system are very important indicators. A good ecosystem can enable humans to gain more benefits from nature, and birds are key participants in providing many of these benefits. The ecosystem services provided by birds can be roughly divided into four categories: Supply…

In nature, speed is a weapon used by many animals for hunting and also an advantage for many animals to escape from the pursuit of predators. Many animals, including birds, will either starve to death or become prey to predators if they are not fast enough. There are over 10000 species of birds in existence worldwide, and since most of them can fly, they are all very fast. However, among the strong, there will always be the strongest. Let's take a look at the top 10 fastest flying birds in the world: 10th place, grey headed albatross Gray headed albatross is one of the fastest migrating birds in the world, and I believe it should be ranked tenth. It mainly inhabits seabirds in the Southern Ocean.The Haiyan Peak on Macquarie Island is the only known grey headed albatross breeding ground in Australia.There is a breeding population of approximately 80 pairs of gray headed albatrosses living here. However, the area is already under serious threat from the rampant wild rabbits. From the name, the head of this bird is indeed gray. Its wingspan is 2.2 meters long and it can fly long distances at a speed of 127 kilometers per hour. Gray headed albatrosses spend most of their lives in seawater, so they have salt glands on their bodies to overcome excessive salt in their bodies. 9th place, Gyrfalcon Gyrfalcon is considered the largest species of falcon. Distributed on various islands in northern North America, Europe, and Asia. The color patterns on their wings are like marble, with black and white…
