Wrens (Troglodytidae)

Marsh Wren (Cistothorus palustris) - HBW 10, p. 414

French: Troglodyte des marais German: Sumpfzaunkönig Spanish: Cucarachero Pantanero
Other common names: Long-billed Marsh Wren; Eastern Marsh Wren (“nominate group”); Western Marsh Wren (“paludicola group”)

Taxonomy: Certhia palustris A. Wilson, 1810, Pennsylvania, USA.
Sometimes placed in a monotypic genus Telmatodytes, but probably closely related to C. meridae and C. apolinari. Recent studies of song types suggest that W races (“paludicola group”, also including browningi, pulverius, plesius, aestuarinus, clarkae and deserticola) constitute a separate species from N & E ones (“nominate group”); this possibility supported by DNA studies of populations in limited area of sympatry, where there appears to be an effective reproductive isolation even in habitats where individuals ..

Affinities of isolated C Mexican race tolucensis uncertain; studies required. Sixteen subspecies recognized.
