Indian Cuckoo

The Indian cuckoo is a solitary and shy bird, found in forest and open woodland at up to 3,600m. It ranges from India, Bangladesh, Bhutan, Nepal and Sri Lanka east to Indonesia and north to China and Russia (Wikipedia, general species account).

It is a brood parasite. The male diverts the attention of the hosts from their nest, giving the female time to lay her single egg, mostly in the nests of drongos and crows. The female removes and eats an egg from the host nest before laying her own. The sources opened give no size or call detail.
