common hawk-cuckoo ( Hierococcyx varius ), brainfever bird , पापीहा Saryu wetland Ayodhya March 17 Nikon Gears Full screen mode recommended for details 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.
