The song of birds
"Cui-cui", "Rou-rou", "Ti-ti-ti-ti", the songs of birds are very diverse and beyond the pleasure of hearing them, their meaning is very varied.
Differentiating between singing and shouting
Most birds use calls to warn of danger, to call other birds, to defend their territory. Each species has a large number of calls specific to each situation.
One very special and generally easy to recognise call is the song, which is longer and more melodious than other calls. Birds sing mainly during the breeding season to attract females to breed. It is also a way for mates to recognise each other, as each individual has a unique vocal signature. Some species sing throughout the breeding cycle, while others stop when they start laying eggs or raising young. In birds, song is produced by an organ called the syrinx.
Hearing a bird sing does not necessarily mean that a nest is present. Some birds may sing without finding a mate or sing during their migratory stopover.
Apart from reproduction, singing is also a way of defining and defending one's territory. The song of some species can be heard in autumn or winter, as in the case of the Robin, which is solitary and defends its territory all year round.
Songs are characteristic of each species, so you can recognise a bird without seeing it and only by hearing it sing. The best time to listen to birds singing is in spring, so don't hesitate! Let's go outside and listen.
How to recognize a song?
To be able to recognize many bird songs, you have to be able to describe them. As soon as a bird sings, you will have to ask yourself some questions:
- Are there stanzas, i.e. a succession of notes, and are they repeated?
- Do they go up or down?
- Does the sound get louder or softer during the stanza?
- What is the timbre of the sound: clear, croaking, squeaking, ...?
- What are the rhythms with which the notes are played?
A bird song can also be described in the alphabet with syllables like "tuit, groû, ou-roû-coû". Circumflex accents correspond to notes that are accented, but pitches and some rhythms are not indicated.

Watching a song is possible!
Humans use their vision more than their hearing, so it is possible to represent the song visually with the help of a sonogram.
On the sonogram, time is represented from left to right. As in a timeline, the elements represented on the left happened before those represented on the right. The marks represent the sounds. The darker they are, the more intense the sound. The closer the marks are to the top of the graph, the higher the sound, and when the marks are close to the bottom of the graph, the lower the sound.
