Field notes

  • Males possess a distinctive white patch at the base of the primary feathers, which is often visible even when the wing is folded.
  • The species is highly nomadic, frequently shifting its geographic presence to track the localized seeding cycles of various grass species.
  • While males are visually distinct, females are olive-brown and nearly identical to several other species in the genus Sporophila.
  • It is primarily a montane seedeater, typically occurring at elevations between 1,000 and 2,500 meters along the Andean slopes.
  • During the non-breeding season, they frequently join large, mixed-species 'seedeater clouds' to forage in agricultural fields.
Habitat
Grassy clearings, pastures, and agricultural edges, often near humid forest or scrubland.
Range
Andean highlands from western Venezuela and Colombia through Ecuador and Peru to northern Bolivia.
