The occurrence of this species on Kina Balu is interesting, 

 as showing a very distinct relation between the avifauna of 

 the mountain and that of High Sumatra. 



[This rare Cuckoo frequented Kina Balu at about 4000 

 feet. It was evidently the pairing-season in March, as they 

 were then very noisy, whistling a good deal in the tops of 

 the trees, especially towards evening.]
