Abstract

We report the complete mitochondrial genome of two specimens of Orange-billed Sparrow Arremon aurantiirostris from Colón Province, in central Panama. The two specimens were collected on the same day, and at the same locality; however, they showed substantial divergence (6.3% average pairwise divergence among coding genes). A survey of ND2 sequence variation across Panama suggests that this divergence is the result of geographic differentiation and secondary contact. This high level of mitochondrial divergence among co-occurring individuals raises the possibility of multiple biological species in Orange-billed Sparrows. Our results are yet another demonstration that much remains to be discovered regarding avian biodiversity in Panama and throughout the Neotropics.
