Fig. 3. Responses of razorbill adult males (A,B), adult females (C,D), and chicks (E,F) to playback experiments. The upper row (A,C,E) shows scores of the number of calls given in response to playbacks (mean ± S.E.M.). Note the different scales. The lower row (B,D,F) shows boxplots (mean, median, 25^th-75^th percentile, and minimum/maximum; refer to key in F) of the composite scores (combination of call, orient and taxis) in response to playbacks. *P<0.05, **P<0.01, NS, not significant.
