From: Sex differences in behavioural and neural responsiveness to mate calls in a parrot
Call response in experiment 2.
(a) Each bird was given three behavioural tests, before pairing and at 0 month and 1 month after separation, which are designated ‘pre’, ‘post(m0)’ and ‘post(m1)’, respectively. (b) Mean (+ s.e.m.) call-response ratios in experiment 2. Asterisks denote significant differences from chance level (dashed line) at m0 and m1 (*P < 0.05). Females showed a significantly greater response ratio to mate calls than males on separation and at one month after separation.
