Means are shown with the bold line, and shaded boxes represent standard errors. Data were analyzed using a general linear mixed model. Boxes with different letters denote post hoc statistical differences between treatments (cowbird chatters n = 18, warbler seets n = 13, redwing chatters n = 16, blue jay calls n = 16, wood thrus songs n = 17). For p-values of post hoc comparisons, please refer to Supplementary Table 2.
