1 64 Lloyd's natural history. 



" Though greatly affecting dense forests, these birds are also 

 partial to bamboo-jungle 



" Their call, which is often heard, especially towards dusk, is 

 a rolling whistle, iv/iezv, wJuw, repeated many times, and wind- 

 ing up with a sharper and more quickly uttered ivhew. The 

 sound is very easily imitated, and the birds are easily enticed 

 to approach one by the imitation, and this is the way in which 

 natives usually secure them. 



"This species certainly perches at times, for I have seen one 

 fly down from a small tree." 



Nest. — A mere lining of leaves and twigs placed in a slight 

 depression at the foot of a large tree (^Cripps). 



Eggs. — Four in number; pure white, broad ovals, rather 

 pointed towards the small end ; shell fine, rather glossy. 

 Average measurements, 1*38 by i'i2 inch.
