Hi, with one omni you loose all spatial information that make the recording
pleasant and similar to the real listening experience. For scientific use
mono recordings are useful and often used, e.g. with ultradirectional
microphones and parabola, or to monitor for the presence of singing species
in an area, however, other than more pleasant for listening, stereo
recordings add spatial information that can be useful to discriminate
animals vocalizing in different positions or make easier to "isolate" - the
task is done by our brain - a noise coming from a direction different from
the direction of the song .... to maximize localization capabilities
special mic configurations are often used.
I would encourage you to use two microphones and choose the configuration
you prefer, e.g. coincident stereo with two cardioids, binaural with two
omni, or largely spaced microphones ....
