Asian Koel male has a ruby red eye, skulks around in thick foliage, female lays eggs in crow's nest

The Asian Koel is a familiar songster and a brood parasite that lays its eggs in the nests of other birds, such as crows. The male has a ruby‑red eye and a blue‑black sheen to its feathers, and it skulks around in thick foliage before calling out its loud cuckoo call. The female is a branded brown and whitish. The bird prefers the shade and anonymity of a shaded grove before it starts to call out its loud cuckoo call, well known to those who live in India's hot and summery months.
