What are songbirds and what are they?

“Some things can be songbirds instead of impressive singers,” said Audubon On-site editor Ken Kaufman. So, what if singing ability cannot make songbirds become songbirds? This problem is actually more complicated than it seems.

The public may use the term loosely, but for scientists, “Songbird” has a more detailed meaning: it refers to a specific suborder of birds. All songbirds are perching birds, a command called passerine birds, they have a unique arrangement of toes that help them grasp the branches.Passerines are divided into three suborders, the largest of which is sparrow. The birds are in sparrow The suborders are called oscines, or songbirds. This suborder includes more than 4,000 species, from the compact golden crown king to the larger common crow.

Although their sizes and musical talents are different, all songbirds have one thing in common: precise control of highly specialized vocal organs Called syrinxAlmost all birds use syrinx to make sounds, but oscines have a higher degree of mastery of them. “The biggest difference is not the syringe itself, but the muscles around it,” Kaufman said. “Oscines have a very complex set of muscles attached to the syrinx, which allows them to be better controlled.”

When a bird exhales, it activates the muscles that control the lumen Series filmWhen air flows through these membranes, they vibrate to produce a specific tone. Because songbirds can best control their vocal organs, they can create the most dramatic ballads.

Another feature that makes oscines unique is that although other birds inhabiting produce their songs by instinct, songbirds will learn them.research shows Songbirds hatch with rough templates of songs But you need an adult tutor to become a professional singer.Young songbird Start wiretapping Act as chicks to their parents and other adults. Some people only have a few months to learn their songs, while others, such as European Starlings, can be added to their playlists as adults. “Songbirds use this ability to learn songs to produce very complex and large-scale reports,” sDonald Crowesma, Retired ornithologist who studies bird song.OhBirds have only a few tracks for them to use.

In other words, birds don’tt always fits the neat category; Crosma Recent work show Three Weeping Bell Birds-Central American birds belonging to different suborders-may also rely on learning to hone their own tunes, which shows that song learning exists outside of oscines.

Although there is no authoritative definition of what constitutes a birds’ song and its screams or other noises, most experts agree Two key functions Birdsong: Defend the territory and courtship. The better the songbirds perform vocally, the more likely they are to achieve their goals. In the northern hemisphere, male songbirds are responsible for most of the singing.Tropical species Better matchBecause men and women often share Duet Performance.

Although most songbirds usually adhere to the same basic song template, individuals occasionally add extra notes or change the pitch. These changes may sound new and exciting, and help attract more partners. “ThereIt will be an innovation, which is obviously very attractive to women, and then this innovation will spread to the entire population like wildfire,” said Heather Williams, a biologist at Williams College. “Just like humans. Like any fashionable things in culture, they can pass things on from generation to generation, or for birds that continue to learn as adults, they can change between generations. ”

Therefore, the melody of songbirds is always evolving.Most diphtheria sparrows in western North America used to sing Oh sweet canada canada canada until A new song sounded In the past two decades.Now they sing Oh, sweet Kannakanaka.

On the other hand, some songbirds have no songs at all, Kroodsma said, he cited the example of an ordinary crow. “It belongs to the songbird taxa, but it really doesn’tThere is not a single song. “What’s more confusing is that some non-songbirds have complex sounds. “I heard the flycatcher do a lot of things that sound like songs to me,” he said.

So, to sum up, not all songbirds are talented singers or even singing, and not all singing birds are songbirds. However, if you want to impress your friends, you can tell them that real songbirds are also called oscines, and they have special control over special organs called syrinx. Or, just relax, don’t think too much, and enjoy the symphony of nature.
