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 know the bird. It lived in flocks in tall trees, ov.er 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 on 

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

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

 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 t^kcMi from P)eebe (Our Search for a 

 Wilderness, p. 1^>H) : — ''TIk; (Jold or Greenheart Bird, another 

 mcmi)er of the Cotingas or Cliattorers, whii-h is as remarkable for 

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

 it is very ventrilofjuial and ditlicult to locate. When directly 

 beneatli tiie sound, it se*'ms to come from the to[)S of the highest 

 trees, a lunidred feet up, wliereas in all probability the bird is not 

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