Extended Data Fig. 4: Yellow warbler responses to playbacks.
From: Learned use of an innate sound-meaning association in birds
Responses of yellow warblers (Setophaga petechia) towards 30 s playbacks of brood parasite-context whining vocalizations by superb fairy-wrens (Malurus cyaneus), conspecific predator-context chip, conspecific brood parasite-context seet vocalizations and wood thrush (Hylocichla mustelina) song, a non-threatening control (N = 14 for all treatments). Generalized linear mixed models were used (see Methods for more detail on statistical procedures). Boxes denote median and interquartile ranges, whiskers denote 1.5x interquartile range, and dots indicate data that lies outside of 1.5x interquartile range.
