White-rumped Monjita (Noivinha-Branca)
Typical areas of countryside, spends most of the time motionless, resting on isolated trees in the landscape, electricity poles or fence posts. It inhabits the field, sometimes next spring (Xolmis cinereus). It is migratory.
Lives alone or in pairs, and little-noticed for her singing, rarely issued. Day is quiet, surprisingly early with his singing intense: a sound monotonous, repeated every 1-5 seconds, infrequently do you hear the whistle even at night.
