The most feathered bird in the world
6. Swan
Physical features: The swan is a large white bird with the most feathers, more than 25,000.
Habits and behavior: Swans are winter migratory birds that prefer to live in groups in lakes and swamps, feeding mainly on aquatic plants. Swans behave loyally, socially, and are able to form strong partnerships throughout life.
Habitat and distribution: Swans are widely distributed, mainly in the Northern Hemisphere, including Europe, Asia and North America.
Conservation status: Swans are currently assessed as least concern globally, but in some areas, such as China, they still face threats such as habitat destruction and illegal hunting.
The smallest bird in the world
7. Hummingbird
Physical characteristics: The hummingbird is the smallest bird in the world, with a length of about 5.6~6.5 cm, smaller than a fly, with an average weight of only 2 grams, and the length of the mouth and tail feathers accounts for a large part of the entire length.
Habits and behavior: Hummingbirds feed mainly on nectar, and their slender beaks are particularly suitable for feeding on long tubular flowers. It can eat 1500 flowers in a day, and is an important pollinator of tropical flowers.
Habitat and distribution: The hummingbird is found only on the islands of Cuba in Central America and is endemic to Cuba.
Conservation status: Due to habitat destruction and overfeeding, the number of honey-sucking hummingbirds is gradually decreasing and is currently listed as endangered.
The fastest sprinting bird in the world
8. Peregrine falcon
Physical characteristics: Peregrine falcon is relatively large, with a body length of 38-50 cm, a wingspan of 95-115 cm, and a weight of 647-825 grams. They have sharp claws and curved beaks.
Habits and behavior: Peregrine falcons usually fly at a level speed of only 50-100 kilometers per hour, but the fastest dive speed can reach more than 300 kilometers per hour. They feed on other birds and are highly skilled at hunting.
Habitat and distribution: Peregrine falcons have a wide range of ranges, including North America, Europe, Asia and Africa. They inhabit open plains, grasslands and desert areas.
Conservation status: Peregrine falcons are currently listed as least concern, but habitat destruction and human hunting still threaten their numbers and survival.
The fastest swimming bird in the world
9. Penguins
Physical characteristics: Penguins are seabirds, although they cannot fly, but their swimming skills are super among birds. There are 18 separate species, the largest of which is the emperor penguin, averaging about 1.1 meters tall and weighing more than 35 kilograms. The smallest penguin species is the little blue penguin, which is 40 cm tall and weighs 1 kg.
Habits and behavior: Penguins feed mainly on fish, which swim like flight in the water with their wings. Penguins are very interesting when walking on land, leaning forward, staggering and sometimes gliding.
Habitat and distribution: Penguins are mainly found in marine areas of Antarctica and the Southern Hemisphere, including South Africa, South America and Australia.
Conservation status: Penguin populations are declining due to climate change and the effects of human activities, and some species are currently listed as vulnerable or endangered.
The slowest flying bird in the world
10. Hill sandpiper
Physical characteristics: The hill sandpiper is a small and medium-sized wading bird, generally 35 cm long, obese, gray-brown coat, with markings. The two legs of the sandpiper are relatively short, but the beak is long and straight.
Habits and behaviour: The snipe is the slowest flying bird in the world, at just 8 km/h. They feed mainly on dipteroptera insects and small invertebrates such as earthworms and snails, and sometimes plant roots and berries.
Habitat and distribution: The hillless sandpiper has a wide range, with the largest population in Eurasia, preferring to inhabit dark and moist woodland, sometimes in forest swamps and wet meadows.
Conservation status: Snipe populations are not currently threatened, but their habitat is gradually being destroyed and polluted and needs better protection.
