انعطاف پذیری و استحکام ناشی از استرس در تماس های فصلی بین زن و مرد

We show that while calls’ spectral structure is significantly modified by stress, it still allows for the correct classification of calls to the caller. Moreover, we also show that the stress-induced modification of calls’ structure is not a 'general feature signal' that can be detected as a 'stress' signal regardless of identity. Thus, female and male zebra finch calls’ structure show stress-induced flexibility that stays within the range of individual vocal signatures.
