One clear example of duetting that I recall is with Noisy Friarbirds;
one bird starts the song, and the second bird joins in after the first
"phrase" singing synchronously with the first bird.  This is easy to pick
in the simple, "tuneful" song they use, but I think many bird songs are
simply too rapid or complex for the human ear to unravel.
