Female Bengalese finches prefer their father's song to that of other birds' lifelong

Caption

Fig 3. Results of the preference test (vocal behavior). (a, d) Population mean of the frequency proportion plotted against age of testing (the number of individuals of each sex at each age is specified in Table 3). (a) shows the results of calling, while (d) shows the results of singing (only males). A solid line with filled circles indicates female data, and a dashed line with filled triangles indicates male data. The proportion was calculated as the response frequency to the father's song (F) divided by the total response frequency (F + U). (b, c, e) Population mean of the number of trials in which birds vocally responded to either song in the tests conducted at 60 and 120 dph. (b) shows the results of male calling, (c) female calling, and (e) male singing. We used this count data for all individuals (10 males and 10 females) for model fitting. Open bars and grey bars indicate response to the father's song and unfamiliar song, respectively. In all three panels, error bars are 95% confidence intervals. Mean and confidence interval values are summarized in Table 3.
