Yellowish beak, ruby red eye and a bubbling babbling call: Dead giveaway that it's an Asian Koel

This demure brown‑banded bird, the shy female partner of the Asian Koel, hides in tree foliage. Its splash of black and bubbly call signals that you are watching an Asian Koel. The male, with a ruby‑red eye, skulks in thick foliage and is a brood parasite that lays its eggs in the nests of other birds, such as crows. The Koel’s melodious call is well known in India’s hot, summery months, and the male prefers the shade of a grove before it starts its loud cuckoo call. The male is blackish, while the female is branded brown and whitish, and the species is known for calling aloud from hidden locations within foliaged trees.
