how to tell the sex of a duck?

[deedeetheduck]

Ok so i found out that my duck is pekin + muscovy....
How can you tell if my duck is a boy or a girl?? I was told she was a girl but not sure.
I have photos of her on my home page if any of you want to look.

Vent sex, or dns sex. Or wait for an egg, or no egg.

This is an interesting question for a Muscovy cross. I am familiar with mallard type voice differences (girls loud, boys quiet), but don't know what a Muscovy girl sounds like. The Muscovy drakes I know make a raspy noise.
