Step-by-step explanation:
Birds often chirp in the morning, creating a melodious sound. Chirping is a form of aural communication birds use to interact with each other. This communication can serve various purposes, including attracting mates, signaling danger, establishing territory, or simply as an expression of their presence. Some birds, like songbirds, are particularly known for their melodious morning songs. Birds also utilize other forms of communication such as visual signals; for example, wing flapping can be used to communicate warnings about predators. The presence of birds and their conversations often add a lively and harmonious atmosphere to the environment, especially during the early hours of the day.
