The effect of T-treatment on the song bout length (mean of the entire week) in males and females during week 1 and week 3. During the first week of T-treatment males sang longer songs compared to females, however, by week three male and female T-treated birds did not differ in song bout length. Bars with a same letter are not significantly different; bars with a different letter are different for p≤0.05 in the post-hoc tests. Bars marked with an ‘a’ are significantly lower than bars marked with ‘b’. Likewise, bars marked with ‘a,b’ are not significantly different from bars marked ‘a’ or ‘b’.
