I need a duck expert

["Rich Peet" <>]

Given the challenge to record a Bufflehead Duck by Stan of this group 
I targeted them this week.

My fieldguides only say "mostly silent" and female grunts and male 
squeeks. But nothing that resembles an actual "call"

I was recording about 12-15 Bufflehead with other "usual suspects" in 
the neighborhood.  The ducks were about 200 yards out which is normal 
for these ducks to sit in the middle of deep water.  The wind was 15+ 
gusting over 25 and it was a challenge to keep my large dish on 
target. 
Linked is what I recorded. I kept my sample in stereo to assist in 
filtering out the swamp grass. I can say I have not heard this sound 
before.  Can anyone tell me if it is a Bufflehead or if it is known 
to you or unknown to you?  The sound I am talking about is the 5 
flute tones at the same pitch. Recorded in Central MN yesterday.
