Wow - I've been watching ducks for years now but I never saw them do anything like that. Those boys looked like they were auditioning for an Anabolic shoot.

We do have these 3 mallard males that hang around together and terrorize all the female ducks. These dudes roll up, quacking like crazy, and run off every other duck in the yard. Then they stand around with their beaks in the air and quack at each other like "hells yeah, we own this shit".
