Fig. 6

Figure illustrating the probable scenario of gene flow during the last glacial period and character displacement in phenotype within the ‘albiceps complex’. Mustard color depicts breeding range taxon chilensis and blue color depicts distribution of sympatric taxa albiceps and pallatangae. Diagrams of the birds depict the character displacement in belly color. Arrows depict gene flow, with black arrow depicting high gene flow and grey arrow depicting low gene flow. Crossed arrow depicts lack of gene flow
