Many species rely on species-specific acoustic calls for conspecific
recognition and discrimination between individuals (particularly in terms
of female mate choice in discriminating between competing males).  A great
deal of neural recognition of species specific calling has been done with
anurans (frogs and toads).  In many species the male emits a mating call
with a specific modulation rate which distinguishes it from the call of
other sympatric species which may be using the same frequency bandwidth;
auditory brainstem nuclei have been identified and categorized based on
their ability to distinguish relevant components of what Capranica called
the "mating call detector."  If you are interested in the acoustic side of
the question, there is excellent work by R. Capranica, M. Ryan, P. Narins,
C. Gerhardt, A. Simmons and A. Feng.  A lit search on any of these authors
names will yield an enormous wealth of material just looking at the
neuroethology of acoustic communication in frogs.
