Mr. Bartlett, who has lately shot this bird at Sarayacu, has kindly supplied us with 
the following note : — " G. aurovirens is common at this place. They always perch on the 
" tree tops, and at intervals utter a thin short call ; in doing so they bend forward, swell 
" out the throat, and erect the tail over the back. Their note resembles that of a dove. 
" In habits, structure, appearance, and especially in the mode of erecting the tail, they 
" appear closely allied to the Rhamphastidse or Toucans."
