The Yellow-shafted Flicker (Colaptes auratus auratus) and Red-shafted Flicker (C. a. cafer) form a stable, narrow hybrid zone on the western Great Plains of North America. Allozyme data were obtained from 31 structural gene loci for 33 samples representing 246 Northern Flickers from throughout the Great Plains. Flickers were approximately equivalent to other birds in terms of proportion of polymorphic loci (P = 0.207) and average heterozygosity (H = 0.056). There was no concordant variation between plumage characters and allelic frequencies.
Gene-diversity analysis indicated that 92.5% of the genic variation occurred as within-deme heterozygosity ( …
