Cocorico

The French flag is red, white, and blue.

And the cock, or le coq Gaulois, according to this enthusiastic vendor, 

is the unofficial national symbol of France  because he shares the same color scheme. 

He does not look very noble here does he? We do not pluck and eat our national bird.

but if Benjamin Franklin had gotten his bird of choice we certainly would.

In France and Wallonia, the French onomatopoeia for the rooster crowing sound,

 "Cocorico" (cock-a-doodle-doo), is sometimes used to express national pride.
