Hi Chris,

Fascinating! Since you're getting Doppler shifted call sequences from cuckoos, 
can you also determine direction of travel?

Hi Geo,

Thanks!

If I had a stereo setup, I could probably listen to and estimate a direction of 
movement; however, this is best calculated with an array of 3-4 additional 
microphone elements and using time-delay measurements to determine location. 
Such a setup would allow localization of each call in time and space, relative 
to the array. Direction of movement of an individual which called 2-3 times as 
it passed over, could then be determined.

Sincerely,
Chris T-H
