From: Prenatal exposure to incubation calls affects song learning in the zebra finch
The effects of prenatal acoustic playback on song syllable learning in male zebra finches. Boxplots (with individual data overlaid) showing the effects of treatment (incubation calls, n = 13) and control (contact calls, n = 18) playback on the number of song syllables that males (a) copied from their father, (b) failed to copy from their father, and (c) copied from non-father males or improvised. Double asterisks (**) indicate significant difference between treatment and control males (GLMM: z = 2.78, p = 0.006).
