Table 1: Principal component (PC) analysis of life history traits of 53 bird species. Eigenvalues and the percentage of variance explained by each component are given for the three first PC axes, representing those with an eigenvalue larger than 1 (total variance explained is 79.09%). For each variable, correlation coefficients with the principle component axis are given, with the significant values in bold (contributions > average aleatory contribution, 100/n, n=number of variables). Post-hatching growth rate had a large effect size on PC1, but did not load significantly on any of the three PC axis (indicated in italics).
