Agelaius chopi

Paraguay

.

Molecular data suggest an isolated position for this species, but in external morphology it seems closer to Oreopsar bolivianus and Curaeus curaeus; in nesting behaviour and voice it resembles Agelaioides badius. Race megistus sometimes subsumed into sulcirostris. Latter apparently intergrades with nominate in E Brazil (N Minas Gerais, possibly also Goiás). Three subspecies recognized.

Subspecies and Distribution
  • G. c. sulcirostris (Spix, 1824) – NE Brazil E from Maranhão and Ceará and S to Bahia and N Minas Gerais (possibly also N Goiás).
  • G. c. chopi (Vieillot, 1819) – C & E Brazil (N Mato Grosso#R E to Goiás, Minas Gerais and Espírito Santo) S to NE Argentina (S to Santa Fe and Entre Ríos) and Uruguay.
  • G. c. megistus (Leverkühn, 1889) – extreme SE Peru (Pampas de Heath and Madre de Dios) E to E Bolivia (La Paz, Beni and Santa Cruz).
  • Reported also from S Bolivia (Tarija) and extreme N Argentina (extreme N Salta), but racial assignation of these populations doubtful; they may represent feral populations originated from escaped cagebirds.
