Bird sounds, also known as bird vocalizations, include a variety of calls and songs that birds use for communication. These sounds can serve different purposes, such as attracting mates, defending territory, or signaling alarm. Each species of bird has its own unique set of sounds, which can vary widely in pitch, tone, and rhythm. Bird sounds can be categorized into two main types: calls and songs. Calls are short and simple sounds used for basic communication, while songs are longer and more complex, often associated with mating rituals. Understanding these vocalizations can enhance our appreciation of birdwatching and the natural world.
