From: Behavioural response of a migratory songbird to geographic variation in song and morphology
Response behaviour of female and male mates within pairs. Shown is the latency to approach within 5 m for females (red) and males (blue) within pairs (connected dots) for (a) the playback (n =15 pairs) and (b) decoy experiments (n =14 pairs) for all stimuli trials. Females and males differ significantly in their response behaviour, i.e. males approached the presented stimulus with lower latency.
