why do roosters crow????

[soccerguy17]

i was just thinking and heard my roo crow and thought WHY most animals have a good reason for there actions but what are the benifits of crowing or im i thinking about this too much and roos crow because they want to and leave it at that

i'm gonna go with announcing that they are there & they're king to their flock of queens....i dunno. i actually wonder that alot myself. Mine always seems to crow way too much. but he's a rooster, thats his job.

Let's see: `I'm here. This is mine. Stay away!'

I really enjoy all the `talk' in the flock. They have quite a little `language', not all of which is directly associated to food/sex/territory/threat.

But the question is on crowing, and the following link goes into the issue at some depth:

(our roo knows when we're at home in the afternoon and will continue to crow until we come out and free him and his girls to roam - so crowing can have other uses).
