The inexpensive binaural setup I'm suggesting has several caveats: 
First, in order to achieve binaural imaging, the diameter of the tree 
needs to be about the same as the linear distance between human 
ears...somewhere between 5 - 6 inches (12.5cm - 15cm). Second, the 
mics, if Sony ECM55Bs, need to be quiet enough (or the signal loud 
enough) so that you don't hear the pre-amp noise during soft moments 
with little creature or geophonic density. Otherwise, the imaging 
illusion on playback will tend to be messed up. To the extent that 
those two conditions are taken into account, the result will fool 
even the most demanding pros who swear by the more elaborate and 
expensive technologies.
