I was in the Sammamish River Slough recently when I witnessed two Great
Blue Herons doing this wonderful slow motion dance. I have since learned
that this is how they defend their feeding grounds. In all my years of
watching GBH, I had never seen this display before. My apologies, but I
could not avoid the temptation to put it to music.
