White-rumped Monjita

18cm. Identification: may be confused with two other species from the same genus, the White Monjita ( Xolmis irupero ), which is almost totally white, apart from the black wings and tail, and the Grey Monjita ( Xolmis cinerea ), which has the head and upper parts in darker grey. Thus the White-rumped Monjita presents a kind of intermediate color pattern between these two species.
Typical of open fields, this bird spends most of its time perched on isolated trees, light posts and fences.
It feeds mainly on flying insects it catches in short flights, returning to the perch afterwards and also takes small berries.
Very little is known about its behavior.
It is certainly migratory, but its migrating routes are poorly understood.
