With a black head and a blue bill,
Females do not look like males!
You share a secret,
Unlike other birds,
But I'm not going to tell you what it is!
A/N: I'm really not, because you guys would kill me if I did! Look it up on Google. If you've seen Evan Almighty, the fact was mentioned in the movie. Except the movie called it by its alternative name, the Argentine Ruddy Duck.
