Aimed skyward between trees this four foot dish uses its epicentral

microphone to collect sounds focused within its concavity and are output

to the FM transmitter for DSPing at the computer.

Bob Evans uses a similar recording technique aimed vertically to study bird flights and

.voices during migrational overflights Gallagher, T. 1994.  Night Sounds.  Birdscope, Volume 8, Number 3:  1-2.

Secured to this oak tree are multiple vibration-monitoring sensors attached to embedded stainless

steel pins. These are inserted into primary, secondary, tertiary limbs and branches and on several

main trunk positions. Dependent upon breezes and wind gusts each will monitor all movements. top
