Table 2.
Historical specimens of individual birds, with current species and island affiliations, observed heterozygosity and genetic classification based on assignment tests. Specimen labels with ‘m’, ‘d’ or ‘s’ reflect current classifications as G. magnirostris, G. difficilis and G. scandens, respectively. Ho, observed heterozygosity.
