Not exactly duetting, but one could mention the Laughing Kookaburra as
"chorusing"! I guess I can't be the only one who has witnessed as many as
11 kookaburras laughing together, and noted that in those circumstances the
normal single kookaburra laugh is not being performed by all or even most
individuals in the chorus. I noted (from sound and closely observed bill
movements) the some were giving the down beat laugh, and others were doing
off beat rhythm, one even in the old brass band 3/4 time (oom)-pa-pa rhythm
(the oom being silent)!.
