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.

Since you're getting Doppler shifted call sequences from cuckoos, can you also determine direction of travel? -Geo Kloppel -- Christopher T.
