Dawn Chorus

The early morning birds sing their wake up songs to anyone who can hear them. Chirping from the branches, the bushes, and from the sky, they sing from dawn till dusk, they sing for each other but unknowingly they sing for us. The songs of different species of birds vary and are generally typical of the species. In modern-day biology, bird song is typically analyzed using a sound spectrograph. Species vary greatly in the complexity of their songs and in the number of distinct kinds of song they sing individuals within some species vary in the same way. In a few species, such as lyrebirds and mockingbirds, songs imbed arbitrary elements learned in the individual's lifetime, a form of mimicry.
