Habits. According to Schoniburgk (Reis. Guian. iii. p. 722)

 R. erythrorhynclnis ( = R. 7nonilis, ]). 4:54:). The "Macusis" call 

 it Kirima and the " Warraus " BariaJtiapi, 



Schoniburgk also states (Reis, Guian. iii. p. 722) that he only saw 

 one specimen of this species and that was when he was ascending 

 the Humerida Mountains {cfr. vol. ii. p. 214). In colour it was 

 almost identical with R. vitellinus, but the bill was almost the 

 same colour as that of R. erythrorhynchus ( = i^. monilis). 



Mr. Barrington Brown writes (Canoe and Camp-life, p. 291) : — 

 " The small Toucans or Bill-birds are also fond of uttering; their 

 yelping calls of an evening, or during the day on the approach of 

 a shower. AVhen doing so they bob their heads up and down in a 

 most extraordinar}' manner, with their large bills {)ointed upwards." 



Mr. Beebe observes (Our Search for a Wilderness, p. 174) : — 

 "The brilliant white-breasted birds call loudly 'kiok I kiok I' in 

 a hioh shrill tone verv unlike that of their fellows.''^
