Fig. 3

The proportion (A) and meal size (B) for control (cont; gray symbol, white box), supplemented (supl; blue symbol, blue box) and restricted (rest; green symbol, green box) treatment groups in no feed, single feed, and double feed nights in Leach’s storm-petrels in 2007. Scatter plots are shown, and for feeding frequencies (A) the number of burrows is represented by a point for each treatment, while for meal size (B) every night of the study period for each chicks is represented by a point for each treatment. Bar whisker plots show median and variation. Different letters denote differences among feed groups and treatments calculated by post hoc comparisons using Tukey HSD tests. If a group has two letters, for example ‘bc’ it designates that group is similar to any other group that has either a ‘b’ or a ‘c’ letter
