Boxplot describing the latency between the first and second attack (in seconds) of the birds. The dark horizontal line within the box represents the median with the box denoting the first and third quartiles and the whiskers being the minimum and maximum values observed. Upon being presented with no vs 1 eyespot per hindwing (No eyespots: m = 20 s, IQR = 51 s; 1 eyespot/hindwing: m = 5.5 s, IQR = 11.25 s), the latency was significantly higher when the birds attacked the model with 1 eyespot/hindwing after attacking model with none (Mann–Whitney U Test: W = 942, P = 0.0276).
