  • Yellow supercilium and lower eye crescent
  • Olive-green head and upperparts
  • Dark iris
  • Black bill
  • Yellowish legs


South America: found in Peru, Bolivia and Argentina


Formerly placed in genus Basileuterus.


There are 2 subspecies[1]:

  • M. s. signata:
  • Andes of central Peru (Junín to Cuzco)
  • M. s. flavovirens:
  • Andes of south-eastern Peru (southern Cuzco and Puno) to western Bolivia and north-western Argentina


Moist montane forests, forest edges; dense undergrowth along streamsides, at heights from 1500 to 3050 m, though generally above 1800m.



There's not a lot of information available. It is thought they eat mostly on invertebrates, foraging near the ground in the understorey. They will sometimes flycatch.


Virtually no information; juveniles observed in December and February in central Peru.
