Courtship Dance of the Hooded Merganser (Lophodytes cucullatus)

A pair of male Hooded Mergansers (Lophodytes cucullatus) are performing a courtship dance for a female. As they throw their heads back and forth, they make a guttural frog-like sound. Unfortunately, the audio didn't get recorded properly, so it's been substituted with some seemingly appropriate background music for the occasion.
