Sedge Wren (Cistothorus platensis) - HBW 10, p. 412

French: Troglodyte à bec court German: Seggenzaunkönig Spanish: Cucarachero Sabanero
Other common names: Short-billed Marsh Wren (“stellaris group”); Grass Wren (Neotropical races)

Taxonomy: Sylvia platensis Latham, 1790, Buenos Aires, Argentina.
Probably closely related to C. meridae and C. apolinari. Taxonomy complex. Races form three geographical groups: “stellaris group” (North America S to Panama), “aequatorialis group” (NW South America, from Colombia E to Guyana and S to Bolivia) and “nominate group” (S South America, from N Argentina and SE Brazil S to Tierra del Fuego). Wide disparities in vocalizations suggest that these groups likely to represent three distinct species; also, the two Neotropical groups possibly worthy of further subdivision.

Taxonomy: Sylvia platensis Latham, 1790, Buenos Aires, Argentina.
Probably closely related to C. meridae and C. apolinari. Taxonomy complex. Races form three geographical groups: “stellaris group” (North America S to Panama), “aequatorialis group” (NW South America, from Colombia E to Guyana and S to Bolivia) and “nominate group” (S South America, from N Argentina and SE Brazil S to Tierra del Fuego). Wide disparities in vocalizations suggest that these groups likely to represent three distinct species; also, the two Neotropical groups possibly worthy of further subdivision. Proposed race boliviae (from Santa Cruz, in Bolivia) considered indistinguishable from minimus. Twenty subspecies recognized.
