Laughing Kookaburra

I love hearing the kookaburra "laugh" in Australia!  This time I was lucky enough to see one "laughing" as well as hear it.  It was in a built up area and there were at least 8 or 10 kookaburras, so I can imagine the local residents were not as intrigued as me.  They really were making quite a racket.

It's beak is open as it "laughs" and is vibrating as well.  I really needed to take a movie so you could appreciate the call.
