Banded Bay Cuckoo

The banded bay cuckoo is about 22cm long, similar in size to the plaintive cuckoo and the brush cuckoo. It is a brood parasite whose eggs resemble those of its hosts (Wikipedia, general species account).

Incubation and nesting are not well documented. Near Bombay it is known to lay eggs from February to August, and in Assam from April to August, while it seems to sing through much of the year in the Eastern Ghats. The source opened gives no range or plumage detail, and does not name Bhutan.
