Proportion of prey in the Goshawk diet according to five size classes and comparison of prey analysis methods.

Average proportion (% ± SEM) of prey in the Goshawk diet according to five size classes estimated from analyses of pellets, prey remains (feather-and-hair, bone, and feather-hair-and-bone), and camera images. Unidentified preys were excluded from these calculations. Prey analysis methods were compared using repeated-measures ANOVA and Bonferroni-adjusted pairwise comparisons (see Table 1 legend for details).Proportion of prey in the Goshawk diet according to five size classes and comparison of prey analysis methods.
