Black-and-white Monjita
The Black-and-white Monjita is a vulnerable flycatcher of open grasslands, marshes, and agricultural land in southeastern South America. Males are boldly patterned in black and white and are conspicuous as they perch on fence posts and low shrubs. It is threatened by the conversion of native grasslands to crops and eucalyptus plantations.
