    Wheatcroft et al. show that nestling pied flycatchers preferentially beg in response to songs from their own population’s dialect. Nestlings beg weakly to songs from other populations and from collared flycatchers, a closely related species. These findings suggest that cultural evolution drives the emergence of pre-mating reproductive barriers.
