Hudson says : "This is a pretty and elegant bird, though possessing no 

 bright colours ; they go in pairs in the warm season, but in the winter unite

 dulating flight. On being approached they utter a series of low ticking

 is quite common in the thickets along the Rio Negro, in the neighbourhood 

 of Carmen, but following up the river appears to become much rarer."
