In fact, birds of the order Shearlands are masters of air currents and often fly with the help of the power of strong winds.
There are about 20 species in 8 genera of petrels, which are most abundant in the Pacific Ocean, less common in the Atlantic Ocean, and not in the northern Indian Ocean. There are 2 genera and 4 species in China.
It is an echinoderm belonging to the class Starfish. What we usually call starfish includes two species: the sea disk car and the petrel. The difference between the Haipan car and the Haiyan is that there is a clear separation between the wrists and the middle disc of the Haipan car, while the various wrists of the Haiyan are not separated from the middle disk.
From a professional point of view, the name starfish is the name of the class, while the sea pan car and petrel are the names of the species.

The Swan is a champion flyer, flying up to 9 kilometers and flying over the world's highest mountain, Mount Everest.
The swan is a winter migratory bird that prefers to live in groups in lakes and marshes, and feeds mainly on aquatic plants.
In China, they fly in large groups from the south to the north every month to lay eggs and breed in the northern border provinces of China. The female swans lay their eggs in May each year, and then the female hatches her eggs, and the male goose guards her side and does not leave for a moment. After October, they move south in groups.
Wintering in warmer climates in the south and recuperating. During the breeding season, it mainly inhabits open lakes, ponds, swamps, slow-flowing rivers and adjacent tundra lowlands and tundra swamps, and in winter it mainly inhabits large lakes, reservoirs, ponds and river bays with many reeds, cattails and other aquatic plants, but also in wet meadows and flooded plains, swamps, beaches and estuaries, and sometimes even in agricultural fields. More than 20 of them formed a small group, lined up in a line of "one" or "people", and sang while flying.
It migrates south in mid-September every year, and covers spring in the north often from June to August.

The black and white vulture generally flies at an altitude of 6,000 meters and is the highest known bird, capable of flying at an altitude of 11,000 meters. Their hemoglobin-d subunit has a high affinity for oxygen, allowing them to inhale oxygen more efficiently at low pressure in the high troposphere. In 1973, they were sucked into the aircraft's jet engines at an altitude of 11,000 meters.
Black and white vultures live in the arid, mountainous areas of Africa, such as semi-deserts and desert edges. They are highly social birds and live in large groups. They can fly at speeds of up to 35 kilometers per hour to forage for food up to 150 kilometers away from the nest.
Their nests are built on rocky reefs or in acacia trees. When the thermals rise two hours after sunrise, they leave the nest and forage for food on the plains. They can wait for days for the predator to leave the carcass.
Sometimes they also hunt live prey. They are generally very quiet and will only make calls when they are inside a nest or next to a dead body.

The highest birds to fly are: black and white vultures, gray cranes, alpine vultures, bar-headed geese, whooper swans.
1. Black and white vultures
Known to be the world's tallest flying bird, can reach an altitude of 11,000 meters. Due to the thinning of oxygen at this height, the bird's blood has a special hemoglobin that absorbs oxygen more efficiently.
2. Gray crane
This bird has different habitats in summer and winter, in summer they live in Northern Europe and Asia, and in winter they migrate to North Africa and fly over the Himalayas, where they can fly up to 10,000 meters above sea level.
3. Alpine vultures
The alpine vulture is one of the world's tallest birds, often soaring at an altitude of 6,000 meters, reaching up to more than 9,000 meters and flying over Mount Everest. Moreover, the alpine vulture has a large body and large, wide wings, which is very suitable for long, long-distance flights.
4. Bar-headed geese
It is a migratory bird that lives in Central Asia and migrates south during the winter months. They can even fly up to 8,800 meters above sea level, and they have a lot of red blood cells that can absorb oxygen even at low concentrations.
5. Whooper swan
These large migratory birds usually appear in southern Eurasia during the summer months and then migrate to the west to breed in the winter. Although they usually fly at an altitude of around 2,400 meters, the highest altitude they have ever flown has reached 8,200 meters.

Sometimes they also hunt live prey. It is mainly found in south-central Africa, including the southern part of the Arabian Peninsula and the entire African continent south of the Sahara Desert (Tropic of Capricorn).
It's a bit of a no-brainer, because the most advanced and highest are completely different things, should I be the most advanced plane or the highest flying plane? The most advanced upstairs has already been said, let's just say the highest, the highest flying plane. >>>More
