12 cm (4¾ in)

  • Black head
  • White patches below eyes and above lores
  • Black band across the breast
  • Broad rusty collar round the neck
  • Long broad tail
  • Thick bill with rounded culmen

Female is relatively well marked, showing shadows of the male's pattern (search gallery for at least one image using link below).


In large parts of Brazil it is much paler in the non-black areas than from other parts of its range. These paler birds should belong to subspecies collaris


South America: found from Bolivia and Brazil, through Paraguay, and Uruguay to northern Argentina.

Three subspecies are recognized[1]:

  • S. c. ochrascens:
  • East Bolivia (Beni) to western Brazil (northern Mato Grosso and western São Paulo)
  • S. c. melanocephala:
  • S. c. collaris:
  • East Brazil (southern Goiás, Minas Gerais, Espírito Santo and Rio de Janeiro)


Flooded lowland grassland and shrubby marshland also open countryside close to water.


Often in pairs to small flocks usually only containing one species.


Their main diet consists of grass seeds, with the addition of some insects.


Their song is a rapid ascending and descending warble.
