user3141: Questions like How did the roar evolve from snort?
and others https://biology.stackexchange.com/search?q=roar
could maybe use tags like sounds, vocals etc.?

user3624: There is communication and ethology, which are both relevant for all questions dealing with different forms of animal communication. Maybe we also need a more specific animal-communication (or zoosemiotics). For a tag dealing with auditory animal communication I would prefer animal-vocalization (or just vocalization). Some sort of vocalization tag would probably be usefuls to also deal with physiological issues/adaptations for animal vocalization. I don't like sounds, since it's very vague and could be used for widely different purposes.
