If you are visiting Mt Kinabalu between February and April, you would most likely hear the 3 note call of the Sunda Cuckoo Cuculus lepidus.  Reduced vocalisation during the other months of the year makes it more challenging  to look for then, even though it is a common resident here.  It used to be lumped together with Oriental Cuckoo but is now a species on its own, based on differences in size, call and plumage.
