winter plumage the feathers are margined with brown and buff above, head 

 and hind neck uniform brown, with a pale buffy median stripe on the crown 

 and whitish superciliaries ; below, feathers frosted with pale buff edgings. 

 All of these buff and brown tips are later lost through abrasion, the uniform 

 black plumage resulting. 



Female brown above with black centers to the feathers of the back and 

 head as in the winter male, below buff with an ashy tint, feathers with median 

 black streaks ; under lesser wing coverts and edge of wing yellow. 



Geographical Range. — Paraguay through Argentina to Patagonia (Chu- 

 pat and Rio Negro). 



Apparently this species does not reach the country covered by the Prince- 

 ton explorations. 



Mr. Peters at Rio Negro found it " a common resident, confined, however, 

 to the reed beds. In western Patagonia it appears to be migratory, since none 

 were seen at Huanuluan prior to the general rush of migrants September 6. . 

 The flocking process was commencing here early in January but by the latter 

 part of the month the species had apparently withdrawn from that section. 

 Late in December it swarmed about the edges of the great /w/^^/at Neluan, 

 twenty miles south of Maquinchao." (Bull. M. C. Z. Ixv. No. 9, p. 336.)
