More Sooty Grouse Songs
Sooty Grouse are a wonderful sight to see!  The yellow air sacs of the displaying male shout out to any observers that he is on breeding territory.   The owl-like sound that emerges from the sacs undoubtedly resonates his intent:  "This is my territory!"   Check out his run across the snow in early morning.  We were lucky to see both male and female.
