Friends, nest friends, hello, today is a good day, not only march 8 women's day, but also the second day of the lunar calendar "dragon up", here to wish the majority of goddesses happy holiday, and male compatriots are a good time to show their own performance.
At the same time, when the dragon looks up, the male compatriots can go to get a haircut, because the lunar dragon looks up and the folk tradition of this man's haircut is rumored to be quite good all year round.
Let's move on to the topic of swiftlets.
We know that bird's nests are nests made by swiftlets of the Swift family Swift family from their saliva and impurities such as down feathers and seaweed. Today we will take a look at the characteristics and habits of swiftlets, as well as the status of swiftlets among birds.
When we usually say swiftlets, we mostly refer to the genus swiftlet and its relatives are more closely related to the genus of dwarf swiftlets, which is a small type of bird. They are also suborder ornithopods, Swifts, Swifts, and resident birds. Ornithopods are divided into two suborders, the Paleoornithidae and the Present Ornithopods, and the existing ornithischia can be divided into the three general orders of the suborder Avians: the General Order of the Ancient Jaw, the General Order of Wedgewing, and the General Order of the Present Jaw. The surviving birds in China belong to the general order of present jaws.
The present jaw order is the main trunk of birds, there are 21 main orders, including the vast majority of birds, due to the well-developed keel process attached to the flight muscle, also known as the "protohorax general order". Most of the birds of the order Tomagnatis can fly, are distributed in all corners of the world, and can adapt to a variety of different living environments.
Introducing the swiftlets:
As mentioned earlier, there are a total of 21 orders of birds in the general order of the jaw, including: goose,chicken,submersible, swift, rat, Dharma monk, finch, and so on.
Swifts are one of the orders Ornithopods, and birds such as Swifts are also known as "Swifts".
Swifts are small climbing birds with hermaphroditic and shiny plumage. The skull is sparrow-palate or split-palate; the beak is flattened, with a slightly curved tip, a broad base, and no whiskers; the wing is pointed long, with 10 long primary flight feathers and a short set of secondary flight feathers, the fifth flight feather is present or absent; the caudal shape is variable, mostly forked, with 10 tail feathers; and the salivary glands are developed.
Swift birds predominate in groups, nesting in caves and crevices in buildings. The nests of birds of this order are mostly bonded with saliva, so that the nests can be fixed to buildings or rock walls. They are capable of flying, fast and agile, hovering, and preying on insects and other foods in flight.
Swift birds are found all over the world, mostly in the tropics, such as the coastal countries of Southeast Asia.
