Coracina javensis
Habitat
Subtropical or tropical moist lowland forest
Range
Himalayas through Southeast Asia to east China and Taiwan; also Java and Bali
The Oriental cuckooshrike is widely distributed from the Himalayas through Southeast Asia to east China and Taiwan, and is also found on Java and Bali. Its natural habitat is subtropical or tropical moist lowland forest. Its range was formerly restricted to Java and Bali, under the name Javan cuckooshrike (Wikipedia, general species account).
That short account is the only source read for the Bhutan guide. No plumage, size, diet or breeding information was found, so none is stated, and the entry is kept as short as the evidence allows.
