What iis the purpose of the actual crow?

[dainerra]

In Southeast Asia, : A long time ago, when the world was new, the sky held nine suns. The land was hot, the river dried up, and crops began to die. The people decided to ask their best archer to shoot the suns out of the sky. The next day, one by one, he shot the suns. Frightened, the last remaining sun hid behind a mountain where the archer could not reach her. Soon the people realized their mistake. The world grew cold, and the crops did not grow. The people spoke gently to the hiding sun to coax her back. They also asked animals and songbirds to try, but none could convince her to return. Finally, someone suggested the rooster, because he was fearless and would not give up. Agreeing to help, the rooster crowed three times, and the sun, believing she was safe, rose from behind the mountain. To show gratitude to the rooster, the sun placed a bit of the morning sky on top of his head.


I've seen them crow for a lot of reasons.

After scaring off a rival or a predator - I'm the MAN!
When one of the hens cackles after laying an egg - those are my women and I'm the MAN!
When he hears another rooster crowing - I hear you, don't come over here coz I'm the MAN!
Randomly throughout the day - I'm here girls; I'm your MAN!

but I don't think there is any real theme to it
