14 Mr. R. B. Sharpe on the 



tangled patches of forest, being rarely met with in the larger 

 stretches of old forest. The natives say that it often feeds 

 upon flesh, killing and eating birds that have been snared, 

 if left long in the traps. I have no doubt that it would take 

 the young from nests, and have watched two little Fly- 

 catchers (Rhipidura javanica) very busy attacking and trying 

 to dinve this Cuckoo from a tree where they probably had a 

 nest. 



The note is loud, " buh bull/' uttered many times, as the 

 bird sits, generally towards the evening, in some prominent 

 position. 



Native name " Bubut," probably from the note. 



Iris, feet, and bill black.]

[This species, unlike the last, is seldom seen except in the 

 " Hang "-grass plains near the edges of clearings. 



This Cuckoo may often be turned up in the coarse grass 

 plains within a few yards, when it rises with a slow flapping 

 flight, often soaring long distances, seldom more than a few 

 feet above the grass, and then dropping suddenly out of sight. 



It is plentiful in Labuan, and, like C. eurycercus, is most 

 often heard towards evening as it perches on some low post 

 or bunch of beaten-down grass. 



I had an egg given me, supposed to be of this species, 

 which was white ; it was found on the ground under some 

 tangled growth. 



Native name " Bubut." 



Iris brown j bill and feet black.]
