6-27, 1981. 
The male collected at San Antonio, March 9, was noted as being in 
breeding condition. 
The series from the Upper Orinoco agrees with birds from Cayenne 
and Surinam in being brighter and lighter in color and more definitely 
streaked. The Brazo Casiquiare specimens are similar to the Orinoco 
birds. In the Brazilian part of the series the birds from the western 
foothills of Serra Imeri and one from Rio Maturacé are like ruficaudus, 
while the four from Salto do Hug on the Maturacé are decidedly 
intermediate toward remoratus.
