Southern antpipit

The southern antpipit ("Corythopis delalandi") is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is one of two species in the genus "Corythopis". It is found in southern Brazil and the pantanal of Paraguay, Bolivia and Brazil; also extreme north-eastern Argentina. Its natural habitat is subtropical or tropical moist lowland forests.
Distribution.
Range: Pantanal, Cerrado and southeast Brazil.
The range of the southern antpipit is a 3200 km by 3000 km contiguous area of southern Brazil bordered on the west by the pantanal and the southern cerrado. The range covers extreme eastern Bolivia, and extends eastward including the eastern half of Paraguay with the northeast tongue region of Argentina.
Coastal ranges on the southern Atlantic extend from central Rio de Janeiro south to central São Paulo.
There is no intersecting in the northern or western Cerrado with its other "Corythopis" species, the ringed antpipit, though its range extends upstream in the southern Amazon Basin into the northwestern Cerrado.
