First, spread pollen.
Some birds can pollinate flowers, which is beneficial to plant reproduction. Flowers that are open to birds are called bird-borne flowers, which are plants that rely on birds to spread pollen. Birds usually pass flowers mainly in red, and the smell is not obvious. Nectar is usually secreted in the early morning or evening, and the amount of nectar is relatively large. Moreover, many species bloom at low temperature, and there are fewer insects at this time, so the characteristics suitable for birds to spread pollen have evolved. For example: hummingbirds, sunbirds, embroidered birds, woodpeckers, honeyeaters, and parrots.
Second, catch mice. ?
Some birds can catch mice, such as red-bellied eagle and red-bellied eagle. They mainly prey on birds, rodents, insects, frogs, lizards and other foods. Birds will use the speed of diving from high places to prey, like to act alone and have strong territorial nature. It has the habit of spitting "food pills", and its vegetarian diet has digestive ability. Food is often swallowed whole, and indigestible residues such as bones, feathers, hair and chitin are integrated into small balls and spit out through the esophagus and mouth, which is called food pill, also called vomiting.
Third, help fishing and hunting.
Birds can help people to fish and hunt. For example, cormorants are masters of fishing. It has superb fishing ability. It can quickly dive into the water and then fish with its hook. Long-term domestication and fishing can catch 1400 Jin of fish a year. ?
Fourth, preying on pests.
Birds can help people catch pests. For example: swallows, woodpeckers, blackbirds, shrikes, starlings, etc. Swallow: One of the most flexible birds, it feeds on insects such as mosquitoes and flies. Woodpecker: The main food is insects, such as Cerambycidae, Coptera, smelly bedbugs, etc. Thrushcross: The main food is larvae, ants, freshwater snails, cockroaches, locusts, meadow moths, cutworms, beetles, ladybugs and other insects.
Five, inspired the wisdom of mankind. ?
Birds also have a special function, which is to inspire human wisdom and provide principles and blueprints for human beings to explore ideal technical devices or vehicles. By studying the flight of birds, scientists invented airplanes. The unique physiological structure and function of birds provide bionic scientific research topics for the innovation of mechanical systems, instruments and equipment, building structures and technological processes. Such as "pigeon eye radar system", "eagle eye system missile" and so on. ?
Summary:
Birds bring us many benefits. In addition, people will also use homing pigeons to convey information, domesticate geese, chickens and ducks, and become the chickens, ducks and geese we usually eat. ? Wild birds are tender, nutritious and delicious. We will buy pigeons from the market to make soup and chickens to make black-bone chicken rice noodles for nourishment. We can keep a bird in our spare time, listen to its melodious and crisp singing, appreciate its bright and dazzling feathers and dexterous manner, so that people can have a positive rest after work, which not only enriches their feelings, but also enriches their lives.
