The songs produced by each bird are diverse. Some songs can be soft or high, and others can have short or long notes. Frequency and amplitudes can be studied by creating a graph to visually study the sound of the birds. The higher the amplitude, the louder the song produced by the bird. The difference between a song and a call is that songs have patterns, syllables, and phrases whereas call is short and simple. Calls are used for multiple situations for defense, conversation, also to attract mates. Most songs are similar to human songs. Each bird has its unique type of calls and vocalization to attract mates. The tempo and frequency are what attract neighbors and predators. Sound travels much further than distance, by using this physical property, birds can communicate with a larger range to other birds. Not only the vocalization produced by the bird itself but also the environment can affect how the bird is heard by other individuals. Some birds like Great Tits that live in the urban area adapted by a vocalization that will not be erased from the traffic noise caused by human activities and other loudness.
