 This is a medium-sized cuckoo resident in the Indian subcontinent. It bears a close resemblance to the Shikra, even in its style of flying and landing on a perch. The resemblance to hawks gives this group the generic name of hawk-cuckoo and like many other cuckoos these are brood parasites, laying their eggs in nests of babblers. During their breeding season in summer males produce loud, repetitive three note calls that are well-rendered as brain-fever, the second note being longer and higher pitched. These notes rise to a crescendo before ending abruptly and repeat after a few minutes; the calling may go on through the day, well after dusk and before dawn.

Brown boobook  (Ninox scutulata),   Brown hawk-owl  भूरा बाज उल्लू Ayodhya Uttar Pradesh October 2023 Nikon Gears Hand held (night mode) Full screen mode recommended for details This is an owl which is a resident breeder in south Asia from India, Sri Lanka, Bhutan, Bangladesh and Nepal east to western Indonesia and south China. The brown boobook is a medium-sized owl with a length of 32 cm (13 in). It has a hawk-like shape due to its long tail and lack of a distinct facial disk. The upperparts are dark brown, with a barred tail. The underparts are whitish with reddish-brown streaking. This species is very nocturnal but it can often be located by the small birds that mob it while it is roosting in a tree. It feeds mainly on large insects, frogs, lizards, small birds, and mice. The call is a repeated low soft, musical oo-uk ...ooo-uk... which may be heard at dusk and dawn.
