Across different species all modalities are used for communication: visual, auditory, olfactory, tactile- electrolytes (electrochemical signals send impulses for communication) fish, electrical. Communication is the transmission of information from one animal to another in a manner beneficial for the signaling. Intentional transmission (cid:498)intentional(cid:499) doesn(cid:495)t always mean consciously aware (cid:498)intentional(cid:499) means that the purpose of transmission was communication (cid:498)intentional(cid:499) can be in terms of evolutionary/adaptive sense. Bird song & hormonal status: castration reduces singing, androgenic and estrogenic metabolites given together, or testosterone given alone (an androgenic hormone which can be converted to estrogenic metabolites) to castrated males restored singing. Singing in the context of territorial defense is associated with gene regulation in brain centers that controls song perception and production: eg.
