The rooster rises early and immediately begins his God-given task - crowing.
The rooster does not refuse to crow because he cannot sing like a canary; but he does crow as if to him, at least, his work was the most important in the world.
He efficiently does that which is never praised. Whoever heard anyone asking: "Did you listen to rooster crow? Hasn't he a charming voice?"
He awakes sleepers, unpopular, but often necessary.
He is the proclaimer of good news; a new day with glorious opportunities and responsibilities has dawned.
He is dependable. He is persistent. He is an excellent advertiser.
He never complains about having to do the same common task, and he does not worry about compensation or recognition that he should have.
