You have never thought about why, in the morning, when you go out on the balcony, you hear this incredible concert? It's not just noise. It's the voices of birds. Every trill, chirp, and squawk is a message. About fear, love, danger, or simply: "I'm here, and this is my territory." Birds are the best musicians of nature, and they have their own language that people are just beginning to understand. Why do birds sing The main reason is to attract a mate. Males sing to show females that they are strong, healthy, and have a good territory. The more complex the song, the greater the chance. Studies show that females prefer males with a more diverse repertoire. The second reason is to protect the territory. Singing is a signal: "The plot is occupied, go away." Neighboring birds hear and either fly away or start a duet. The third reason is alarm. Birds emit sharp cries when they see a predator (a cat, an eagle). Other birds hear and hide. Some species even imitate the cries of other birds. The fourth is maintaining contact in the flock. For example, crows call out when they find food. Birds also sing for training. Young males learn to sing from older ones, imitating them. It's like music lessons in a bird school. How is a bird's voice structured Unlike humans, whose voice box is the larynx, birds have a lower larynx (syrinx). It is located at the branching of the trachea into the bronchi. The syrinx allows birds to produce two sounds at the same time (the left and right bronchi can work independently). This is where the complex trills and the ability to imitate come from. Birds do not use their lips or tongue to form sounds (they do not have lips). They change pitch by tensing the muscles of the syrinx and changing the airflow. Some birds (like larks) can produce up to 100 different sounds per second. Volume: the loudest singer is the white-throated sparrow (up to 100 dB, like a jackhammer). The quietest is the hummingbird (inaudible from 10 meters). Interestingly, birds ... Read more
