Table S1
Trait means of the Big Bird lineage, G. fortis and G. conirostris.
Table S2
Differences between mean morphology of the Big Bird lineage and (a) the G. conirostris founder (5110) and its G. fortis mate (15210) and (b) means of samples of the parental species G. conirostris and G. fortis. Differences are expressed in units of standard deviations of the Big Bird lineage distributions.
Table S3
Statistics of ordinary least squares regressions of bill size on body size for the Big Birds, G. conirostris and G. fortis in Fig. 3A.
Table S4
Statistics for the regression of bill depth on body size (Fig. S3). The Big Bird lineage and the other two species have almost identical slopes, but the intercepts are conspicuously different: the Big Bird distribution of bill depths has been displaced relative to body size. This recapitulates the same relationship with bill size in relation to body size in Fig. 2A. Bill depth and bill width are strongly correlated (r = 0.72) and vary in relationship to body size almost identically.
Table S5
Genotypes of the Big Birds in clusters on two gene trees (figs. S4-S5).
