Incidentally, the songbird ID apps I've seen in use are mediocre at best at identifying songs. The main problem seems to be that they use AI that is trained on heavily US-centric datasets, and don't seem to take into account location (theoretically easy), or terrain (harder for an app).
I have a mate who uses one when walking his dog and regularly get asked whether it's possible that there's e.g. a Northern Mockingbird in woodland round the back of Brighton (vanishingly unlikely).

Your phone microphone is not stereo. It's a single mic.
With one mic you can only measure amplitude. To determine a direction you'd need to measure the phase difference between two (or more) mics.

Also the wider your ears/mics the lower the frequencies you can determine the direction of. We find it hard to determine the direction of bass because the wavelength is greater than the ear to ear distance. Elephants and whales could locate a tb303 with pinpoint accuracy.
