After the second hour had passed I was becoming bored. I bet stars are neve

BIRD SONG
1 One instance in the animal kingdom with parallels to human music is bird song. Much has recently been discovered about the development of song in birds. Some species are restricted to a single song learned by all individuals, while other species have a range of songs and dialects, depending on environmental stimulation. The most important auditory stimuli for birds are the sounds of other birds, including family or flock members and territorial rivals. For all bird species, there is a prescribed path to development of the final song, beginning with the subsong, passing through plastic song, until the bird achieves the species song or songs. This process is similar to the steps through which young children pass as they first babble and then mimic pieces of the songs they hear around them, although the ultimate output of human singers is much vaster and more varied than even the most impressive bird repertoire.
2
A. restricting
B. surrounding
C. recording
