Habits. Schomburgk states (Reis. Guian. iii. p. 693) in regard 

 to this bird that the first time he heard its note it made him most 

 curious to knovy the bird. It lived in flocks in tall trees, over the 

 tops of which it roamed about. In the low bush it was never seen. 

 It was very difficult to obtain, for, in spite of its shrill voice, its 

 habit of sitting still and its sober ash-grey colour made it almost 

 impossible to be seen. As a rule, when one bird uttered a note, 

 the entire flock repeated the same cry. He was continually hearing 

 this concert all the day long. He once attempted to pick up a 

 winged bird which startled him to a degree by its " ear-splitting " 

 note. Although this bird was so common, its nidification was 

 still unknown to him. The "Warraus" called it Paia-paia, and 

 the "Macusis " and " Arekunas " Pai-paischo. 



The following notes are quoted from Mr. J. J. Quelch (Timehri 

 (2) ii. p. 375), who observed this bird during a collecting trip ou 

 the Abary River, and writes : — " In the forest the shrill piercing 

 whistle of the ' Pi-pi-yo ' or green-heart bird {Lathria dnerea) 

 alone could be heard, and this the only bird seen." He also met 

 with it at the Great Falls, and observes (Timehri (2) iv. p. 115) : — 

 " On all sides the green-heart birds incessantly rang out their 

 piercing ' pi-pi-yo.' " 



The following note has been taken from Beebe (Our Search for a 

 Wilderness, p. 188) : — "The Gold or Greenheart Bird, another 

 member of the Cotingas or Chatterers, which is as remarkable for 

 its voice as it is lacking in brilliant colours. Loud as the call is, 

 it is very ventriloquial and ditScult to locate. When directly 

 beneath the sound, it seoms to come from the tops of the highest 

 trees, a hundred feet up, whereas in all probability the bird is not 

 more than twenty-five feet above our heads. It sits motionless.
