Subspecies
Genus often subsumed in Agelaius or Chrysomus. Analysis of mitochondrial DNA indicates that relationship of present species to two congeners (Pale-eyed Blackbird (Agelasticus xanthophthalmus) and Unicolored Blackbird (Agelasticus cyanopus)) is not close. Individuals somewhat intermediate between nominate subspecies and petersii occur south of 42� south in Patagonia (Chile and Argentina).

The following 3 subspecies are recognised:

alticola (Todd, 1932) - South-eastern Peru (Cuzco, Puno) and western Bolivia (La Paz, Cochabamba and Oruro).
thilius (Molina, 1782) - Chile (Atacama south to Magallanes).
petersii (Laubmann, 1934) - Breeds Argentina (from at least Santiago del Estero, Santa Fe and Corrientes south to Santa Cruz), Uruguay and south-eastern Brazil (mostly along coastal marshes of Paran�, Santa Catarina and Rio Grande do Sul); in austral winter extends to extreme north-eastern Argentina (Salta, Chaco, Formosa) and most of Paraguay, with few records in Bolivia (Izozog).
