12.5 cm Parabolic Microphone & LS-P1

I tried to make a stereo parabolic microphone setup as compact as possible.
I 3D printed a 12.5 cm dish with a focal point at 3 cm. I also printed a 6.5 cm diameter stereo baffle separator, inside which I placed two PUI AOM 5024 omni capsules in an “quasi PZM” position (see here for more info).
To remain consistent with the small size, a compact recorder I used an inexpensive Olympus LS-P1.
I then tried to make a recording at a Cattle Egrets roost (currently about 300 units, which will then double during the winter) located in my large garden at home.
Using headphones you can perfectly hear the blackbird and the robin, where they emit their calls in the midst of the herons’ cries, placed to the left or right exactly where they were in fact.
Clearly the amplification of the small parabolic dish affects only the few high frequencies recorded.
The stereophonic baffle assembly seems to work despite its extreme compactness.
