Names and Taxonomy
Comments: Nine subspecies of winter wren occur in North America; these are separated into three groups based on morphology, plumage and vocal characteristics: the Boreal-eastern, Western-Pacific Coast, and Bering Sea-southwestern Alaska groups. Troglodytes t. helleri belongs to the Western-Pacific Coast group; the Bering Sea-southwestern group comprises the other Alaskan subspecies T. t. alascensis, T. t. meligrus, T. t. kiskensis, and T. t. semidiensis (Hejl et al. 2002). These are now subspecies of T. pacificus following AOU (2010). Recent genetic work by Drovetski et al. (2004) showed strong differentiation between six groups, or clades, worldwide; they argued for the recognition of winter wren clades as evolutionarily significant units, or even species, and hence recognition of fewer subspecies.
