Song: Bird singing is a complicated learning process. The process of learning songs can be divided into two stages. In the sensory learning period, young birds must hear the songs of adult birds and form a song template memory. During the sensorimotor learning period, songbirds gradually establish a stable song through auditory feedback and template matching.
In some birds, the unique songs are not learned, but inherited. But in some other birds, such as young swallows and finches, they have to hear the songs of adult males to learn.
Explanation of words:
Song: The songs of birds and animals (especially songbirds). Birds' songs can be divided into three types: singing, singing and singing effect. Singing, also known as singing, singing or singing, is usually a powerful, loud and changeable multi-syllable continuous melody under the control of sex hormones, and some kinds of singing are very melodious.
A kind of sound of birds, which is unique to male birds in order to attract mates and keep watch during breeding season. Compared with birds that communicate with each other, songs are more complex and last longer. From the conspicuous singing of a male bird in his own field, other males can know which species it belongs to, judge the mood of the singer, and even judge which bird it is.
Indigo butterfly knows all this from the details of the same bird's song, but the order of all the notes that human beings pay great attention to is meaningless to birds. In some birds, the unique songs are not learned, but inherited. But in some other birds, such as young swallows and finches, they have to hear the songs of adult males to learn.
Song type:
The songs of birds are as diverse as the kinds of birds, even more than the kinds of birds. The same bird living in different areas will have different songs, just as we humans have our own dialects. However, the singing patterns of birds are very fixed, and females can accurately identify males of the same kind through these songs.
