  • Greyish upperparts
  • Whitish underparts
  • White coronal stripe, more visible when agitated


South America: found in Bolivia, Brazil, Paraguay, Uruguay and Argentina



Three subspecies are recognized[1].

  • S. s. straminea:
  • S. s. subcristata:
  • S. s. munda:
    • Western Bolivia to western Paraguay, extreme southwest Brazil and western Argentina

The last subspecies was formerly considered a full species with the name of White-bellied Tyrannulet.


Shrubby steppes, open woodland, tree groves and gardens, but avoids insides of more closed forest.


Partly migratory in that it leaves the higher elevation areas of the south, going mostly east but also north from there. This is mainly the white-bellied form (munda).


Their diet consists almost entirely of insects.


One frequently heard vocalization starts with some whistled notes followed by a trill.
