I feel like there is some good science regarding the phenomenon of these species sharing accents based on geography, but the summary feels like a stab in the dark as to why. To digress further... I don't see how this is so much to avoid conflict as it is to gain access to benefits from an out group by using mimicry. Think about cuckoo birds or other parasitic species, they aren't mimicking another species to avoid conflict. Some flowers to emit the scent of their pollinating species to attract them. Certainly other types of mimicry are to avoid conflict, like in the case of eyespot patterns, but does emulating accent fit more into which of these?
