 Kiver. 



The adult female appears to be like the adult male, but there is 

 no series available, and consequently we are unable to form any 

 conclusive opinion. 



The young birds differ from the adults in being fawn colour, 

 all the feathers m:irked with black ; these marks assume different 

 shapes on the various parts of the bo<ly.

 Habits. According to Schomburgk (R-ds. Guian. iii. p. 753) 

 this bird is found singly in the solitudes of the thick swampj 

 coast-woods and the borders of rivers in similar districts. The 

 " Warraus " call it OXo/i, and the '" Macusis " Worna. 



Mr. Barrington Broan, who met with the species on the 

 Cartoonie River, remarks (Canoe and Camp Life, p. 47) : — " The 

 call of this bird, which is uttered early in the morning and late 

 in the evening, resembles that of the Jaguar, and thus obtained 

 the name of Tiger-bird."
