Included are 14 species of birds with sufficient sample sizes (n≥6). In the genus Mionectes, we compared M. oleagineus individuals from western Amazonia to the east-Amazonian species M. macconnelli. Indices shown include nucleotide diversity (π), haplotype diversity (h), and F_s values from Fu’s test of neutrality (see text). EE = Eastern Ecuador, FG = French Guiana.
