According to the classification system of the International Union of Ornithologists, there are currently 11,093 species of birds. Keeping wild birds as pets has a long history in China, and various categories have developed. These are mainly divided into two types: those for listening to their songs and those for playing with them. Birds for listening to their songs primarily include songbirds of the order Passeriformes, such as tits, larks, thrushes, mynas, and common mynas. Birds kept for playing with mainly include some birds of the families Finchidae and Shrikeidae within the order Passeriformes, as well as birds of prey of the order Falconiformes, such as the black-headed hawfinch, the hawfinch, and various other birds of prey. Birds are not only among the most beautiful animals in the world, but their songs are also among the most melodious.

Do you know which birds in the world have the most beautiful songs? Today, we'll introduce you to ten of the most beautiful-sounding birds: Lark, Thrush, Indigo Robin, Nightingale, Canary, Leiothrix, Lyrebird, Flying Thrush, Red-breasted Robin, Black-naped Oriole, and Yellow-browed Warbler. The Lark is known as the "singer of birds" because its song is loud and can last for a long time, with a melodious and beautiful tone. So what other beautiful songs do other birds have? Let's take a look.

1. Lark
The lark is a well-known "singer among birds," possessing an exceptional learning ability to mimic the sounds of other birds and small animals. Its call is loud, sustained, beautiful, and can even travel high into the sky. Even when caged, the lark can still display its singing and dancing talents. With proper training, a typical lark can produce more than a dozen different sounds and can continue singing while spreading its wings.
There are many kinds of larks, the most famous of which is the song lark. Song larks are relatively large, with beautiful plumage, and their calls are powerful and adept at imitating the sounds of other animals.

2. Eyebrow drawing
The Chinese thrush is a bird endemic to China. It is not only an important beneficial bird for agriculture and forestry, but also has a melodious and pleasant song, and can imitate the calls of other birds, making it a traditionally kept cage bird for ornamental purposes. The breeding season for thrushes is from the Qingming Festival to the Summer Solstice in the lunar calendar. A pair of thrushes can typically breed 1-2 times a year. In the warm spring months, when the earth is warm and flowers are in full bloom, the male thrush initiates its mating activities, singing loudly to express its affection for the female. Perched on a branch, it sings a song of vows, warning potential rivals against infringing on its mate's bond. The thrush has a highly developed auditory system, is extremely sensitive to sound vibrations, and has a rapid reaction time.
During the breeding season, male thrushes are particularly adept at singing high-pitched and passionate songs, especially at dawn and dusk. Their songs are high-pitched and passionate, with varied melodies, long and continuous, full of captivating musical charm, and intoxicating to the listener. When they sing rapidly, their voices are vigorous and unrestrained, like pearls falling on a jade plate; while when they sing slowly, they are like flowing clouds and water. Especially their long and continuous singing is truly refreshing and awe-inspiring. Therefore, some people call them "singers of the forest" or "bird singers."

3. Indigo chin
The Red-throated Indigo Bird is one of China's four famous birds, widely popular for its red and blue plumage. It is a highly sought-after elegant ornamental bird and also one of the bird world's famous "singers." The Red-throated Indigo Bird is a terrestrial bird, often seen frolicking in dense bushes, reed beds, and marshes on plains.
The male Indigo-throated Robin is beautifully colored and a gifted singer. Their songs are melodious and captivating, full of rhythms.

The Indigo-throated Robin's voice is a true pleasure, a musical feast, immersing listeners in a beautiful symphony. The adjective "melodious" is insufficient to describe the beauty of their voice.

4. Nightingale
The nightingale is a greyish-brown ornamental bird. Although its plumage is not particularly ornate, the nightingale is widely admired for its exceptional singing ability, with a breathtakingly wide vocal range. Unlike other birds, the nightingale is one of the few that sings at night, hence its name. The male nightingale's call is high-pitched and bright, filled with melodious and beautiful tones, and its wide vocal range is the envy of even human singers. In recent years, scientists have discovered that nightingales sing even louder in or near cities, a response to masking noise pollution from urban areas.

5. Canary
Canaries are birds native to the islands of the Canary Islands, Madeira, and Esulize off the northwest coast of Africa. They are beloved for their magnificent plumage and beautiful songs. There are 24 species of canaries, and they are considered one of the most prestigious caged birds both domestically and internationally. Despite their noble image, canaries are very affectionate birds. Young birds can even mimic the calls of larks and thrushes and display remarkable performing talents, such as performing tricks like "catching objects" and "wearing masks." While these birds are beautiful and have melodious songs, keeping canaries requires considerable preparation and care.

6. Lovebird
The Red-billed Leiothrix is a nimble, lively, and beautiful bird with a melodious, clear, varied, and captivating song. Its beautiful plumage makes it a renowned ornamental bird both domestically and internationally. Red-billed Leiothrixes typically do not mimic the calls of other birds, producing only their own unique songs. In captivity, these birds are very active, rarely staying in one place, and frequently hopping around. They only rest briefly when singing joyfully or when the males preen each other. During the breeding season, the males' songs are particularly beautiful and attractive, making them popular pets and resulting in a considerable annual export volume.

7. Lyrebird
The lyrebird is a beautiful and spectacular bird, renowned for its exceptional singing and dancing skills. It can mimic not only the calls of various birds but also a wide range of human sounds, such as car horns, train hissing, the sound of axes chopping wood, road construction machinery, and even human shouts. Its elegant and melodious song and graceful dance have made it one of Australia's most beloved and rare bird species. Besides showcasing its talents during courtship, the lyrebird also happily acts as the "band" at weddings for a bird called the bowerbird. Bowerbirds themselves cannot sing, so they need to invite lyrebirds to perform for their "wedding ceremonies."

8. Travelling Thrush
Like other birds in its genus, the male Flying Thrush has a complex and persistent song. Their call is described as a celebratory hymn, possessing a variety of tones that are repeated and occasionally interrupted. Their calls also vary depending on the time and region. The singing season typically begins in March and continues until late July or early August, with some Flying Thrushes in the east even singing until September. They are also among the first birds to begin singing at dawn, their songs continuing throughout the day and into the night.

9. Red-breasted Robin
The Red-breasted Robin, also known as the British Robin or the Red-breasted Flycatcher, is considered the national bird of Britain and is praised as "God's Bird." It has a warlike nature and prefers to inhabit woodlands, scrublands, forests, parks, and gardens. The Red-breasted Robin's call is clear and melodious, like a flute, and it sings continuously from dawn to dusk during the breeding season, even at night. Active during the day, it is one of the earliest and last birds to sing. Its melodious song, with its varied tunes, is beloved by many.

10. Yellow-browed Warbler
The Yellow-browed Warbler's song has two types: one is a clear and soft call, usually a series of single-syllable "ju," three-syllable "ju-ju-yi," or four-syllable "ju-ju-yi-zhi." When it is restless, it will emit a single-syllable "ju-," usually heard when alone, startled, or during rain. When two or three Yellow-browed Warblers are foraging together in a tree, they will emit a high-pitched call "ju-jue-yi-zhi" as they fly from one perch to another branch or tree, which serves as a call. When there are insects in the trees, they will emit a four-syllable call "ju-jue-yi-zhi" along with body movements while searching for and pecking at food; this is a food-related call. This call can often be heard on cloudy days or after rain due to their frequent foraging activities. The other type is their high-pitched and melodious warbling.
