Figures & data
Figure 1. Egg size and nest predation. Canary and quail eggs were preyed upon in similar proportions (X2 = 0.15, df = 1, P = 0.69).
Figure 2. Percentage of nests predated by each predator group. Birds predated both sizes of eggs in a greater proportion than mammals (X2 = 23.7, df = 2, P < 0.0001). Marsupials preferred to prey upon small eggs (canary) (estimate ± se = −2.16 ± 1.09, z = −1.97, P = 0.04). Rodents did not show a preference for egg size. The numbers below the bars show the mean values. Different letters show significant differences in nest predation between predator groups (P < 0.05) and the asterisk shows the significant difference for egg sizes taken by the Monito del Monte.
