In this study we use mtDNA ND2 gene (1041 bp) to evaluate the relationship between Menzbir's (Anthus [gustavi] menzbieri) and Pechora (A. [g.] gustavi) pipits. Menzbir's pipit is listed in the regional Red Data Book as a distinct, rare species with a small range. We obtained 18 Pechora pipit samples from two localities and 8 Menzbir's pipit samples from a single locality. Sequences of the two taxa appear reciprocally monophyletic and are separated by 6 substitutions (0.6% divergence). Differences between the taxa explained 62.4% of the variation in our dataset. Differences among individuals within localities explained 34.8%, whereas differences between the two Pechora pipit localities explained only 2.8%. Mismatch distributions suggest that unlike the Pechora pipit localities, which either have experienced recent population growth or sustain a stable population size, the Menzbir's pipit population may be declining. Our results suggest distinct taxonomic and conservation status for the Menzbir's pipit.
