Bright blue plumage makes male fairy-wrens flighty

Figure 1. Blue males are more likely to flee in response to the playback of a conspecific alarm call, independent of their prior activity. Responses to low-danger alarm playbacks are shown for fairy-wrens in blue plumage (blue males, image a; blue bars) and brown plumage (brown bars), including males (image b) and females (image c). Response types are flee to cover (dark), intermediate (medium) and no response (light). Individuals were foraging, acting as a sentinel or performing other behaviours (preening, resting and singing) immediately prior to the alarm playback. Values are based on raw data. Numbers indicate sample sizes for responses to the low-danger alarm. (doi:10.1098/rspb.2017.0446)
