Morphological and Molecular Evidence Confirm the First Definitive Eastern White-breasted Nuthatch (Sitta c. carolinensis) for New Mexico
Matthew J. Baumann, Sabrina M. McNew, and Christopher C. Witt
ABSTRACT: We report the first confirmed eastern White-breasted Nuthatch (Sitta carolinensis carolinensis) from New Mexico. The bird was collected on 15 October 2011, at Boone’s Draw, Roosevelt County. Morphological and plumage characters matched those of the eastern White-breasted Nuthatch, the bill being markedly shorter and the back paler than those of the subspecies resident in New Mexico, S. c. nelsoni, and other western subspecies. The DNA sequence of the mitochondrial gene for NADH dehydrogenase subunit 2 (ND2) was an exact match to published sequences from Michigan and Pennsylvania and was phylogenetically nested within a monophyletic and deeply divergent eastern clade.
