Songbird rhythms

An interesting analysis of bird song duets. I'm wondering how mammals do 
this. I was listening to a Bornean Gibbon last week, which also duets, 
but must have a quite different vocal cord setup, and yet manages to 
produce some phenomenal range of songs and calls (in the 10'000 hertz 
plus frequency).
