From: Behavioural response of a migratory songbird to geographic variation in song and morphology
Playback and decoy experiment in females. Behavioural response for the latency to approach within 5 m in (a) playback experiments in response to song of European Stonechats from (1) the local population, (2) a population from 90 km distance, (3) a population from 180 km distance, (4) African stonechats, and (5) control stimuli (Winter wren); and (b) decoy experiments in response to stimuli from (1) local, (2) European, (3) African, and (4) control stimuli (European Robin). Females distinguished between stimuli by approaching the local stimuli significantly faster than all other stimuli. Detailed description of boxplots as in Figure 2; n =15.
