Request for Bird Song experts

Hello

I am a masters student studying sound and music for interactive games.

For my major project I am creating a system of bird song generation, with dynamic changes between calm &alarm calls, due to enemy distance..

This project will involve identifying syllables within bird calls, and also creating probabilities for what syllables will follow each other, then programming them into my system to create a realistic birdsong generator. I will also be programming some macro birdsong interaction algorithms.

I will be focusing on british passerines such as blackbird, wren, redstart and robin.

Anyway the questions...

Are there any bird song experts who:

Have been looking into the structure of birdsong? 

Have been looking at birdsong interaction?

Have been looking into bird calls in reaction to danger?

Also:

Are there any work groups/forums who are focusing on these areas?

If the answer to any of these questions is yes, then please get in touch/point me in the right direction.

Thanks alot

Aiden
