Wrens (Troglodytidae)

Northern Wren (Troglodytes troglodytes) - HBW 10, p. 432

French: Troglodyte mignon German: Zaunkönig Spanish: Chochín Común
Other common names: Wren, Common/Holarctic Wren; Winter Wren (America)

Taxonomy: Motacilla Troglodytes Linnaeus, 1758, Sweden.
It has been proposed, on the basis of DNA analysis, that this species is sufficiently distinct from its congeners (all confined to New World) to warrant placement in its own monotypic genus, for which the name Nannus is available. Recent DNA work suggests that it contains six distinct clades, in, respectively, W Nearctic, E Nearctic, Europe, E Asia, Nepal, and Caucasus, indicating cryptic speciation. Also, vocal differences exist between birds in W Nearctic and those in E, and both differ also from Old World birds, suggesting that at least three species may be involved. Numerous races ..

Numerous races of doubtful validity have been described. Race orii (Daito Is, in Japan) extinct. Forty-four extant subspecies recognized.
