The common hawk-cuckoo (Hierococcyx varius), popularly known as the brainfever bird, 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; like many other cuckoos, these are brood parasites, laying their eggs in the 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.
The common hawk-cuckoo is a medium- to large-sized cuckoo, about the size of a pigeon (ca. 34 cm). The plumage is ashy grey above; whitish below, cross-barred with brown. The tail is broadly barred. The sexes are alike. They have a distinctive yellow eye ring. Subadults have the breast streaked, similar to the immature shikra, and there are large brown chevron marks on the belly. [4] At first glance they can be mistaken for a hawk. When flying they use a flap and glide style that resembles that of sparrowhawks (especially the shikra) and flying upwards and landing on a perch they shake their tails from side to side. Many small birds and squirrels raise the alarm just as they would in the presence of a hawk. The sexes are alike, but males tend to be larger. [5]
They can be confused with the large hawk-cuckoo, which, however, has dark streaks on the throat and breast. Young birds have a pale chin, but young large hawk-cuckoos have a black chin. [6]
During summer months, before the monsoons, the males are easily detected by their repeated calls but can be difficult to spot. The call is a loud screaming three-note call, repeated 5 or 6 times, rising in crescendo and ending abruptly. It is heard throughout the day and frequently during moonlit nights. [7] The calls of females are a series of grating notes. [5] Common hawk-cuckoos feed mainly on insects and are specialised feeders that can handle hairy caterpillars. Caterpillar guts often contain toxins and like many cuckoos they remove the guts by pressing the caterpillar and rubbing it on a branch before swallowing it. The hairs are swallowed with the caterpillar and are separated in the stomach and regurgitated as a pellet. [6]
The type locality of the species is Tranquebar in Tamil Nadu, once a Danish settlement and from where a specimen reached Martin Hendriksen Vahl who described the species in 1797. [8] This species is placed under the genus Hierococcyx, which includes other hawk-cuckoos, but is sometimes included in the genus Cuculus. [4] There are two subspecies, the nominate from India and ciceliae of the hill regions of Sri Lanka. [9] The Indian population has paler plumage than ciceliae. [4]
The common hawk-cuckoo occurs in most of the Indian subcontinent, from Pakistan in the west, across the Himalayas foothills, east to Nepal, Bhutan, Bangladesh and North East India [10] and south into Sri Lanka. Some birds of the Indian population winter in Sri Lanka. In the hills of central Sri Lanka, ciceliae is a resident. It is generally resident but in high altitudes and in arid areas is locally migratory. It is found in the lower elevations (mostly below 1000m) of the Himalayas but in the higher areas, the large hawk-cuckoo tends to be more common. [5]
The species is arboreal and rarely descends to the ground. Its habitat includes garden land, groves of tree, deciduous and semi-evergreen forests. [5]
Like many other cuckoos, this species is a brood parasite, preferring babblers mainly in the genus Turdoides (possibly the only host [4] ) and also reportedly on laughing-thrushes of the genus Garrulax. [11]
Its breeding season is March to June, coinciding with that of some of the Turdoides babblers. A single egg is laid in each nest, blue, like that of the host. The hatchling usually evicts the eggs of its host and is reared to maturity by foster parents, following them for nearly a month. [6] T C Jerdon noted that it may not always evict the host and that young birds may be seen along with young babblers. [12] When moving with a flock of babblers the chick makes a grating kee-kee call to beg for food and the foster parents within the group may feed it. [5] The predominant host species in India are Turdoides striatus and Turdoides affinis . [13] Hawk-cuckoos also parasitise the large grey babbler Turdoides malcolmi . [7] [14] In Sri Lanka, their host is Turdoides striatus . [15]
Parasitic eye-worms in the genus Oxyspirura have been found in the orbital cavity of the species. [16]
The call of this bird has been popularly transcribed as brain-fever in English (in some old books, this name is also incorrectly used for the Asian koel). Frank Finn noted that [H]is note, however, fully entitles him to his ordinary designation, whether from its "damnable iteration" or from its remarkable resemblance to the word "brain-fever" repeated in a piercing voice running up the scale. [17] Other interpretations of the bird call include piyaan kahan in Hindi ("where's my love") or chokh gelo (in Bengali, "my eyes are gone") and paos ala (Marathi, "the rains are coming"). In Bodo, the call sounds like "haab fisha houwa", which means dear son (where are you).
The call "Pee kahan" or "Papeeha" is more accurately represented by the shrill screaming "pi-peeah" of the large hawk-cuckoo Hierococcyx sparverioides , which replaces the brainfever bird along the Himalayas and its foothills. [6]
The brainfever bird's call may be heard all through the day, starting early before dawn and frequently during moonlit nights. [7] A novel by the Indian author Allan Sealy is named after this bird. [18]
Bole Re Papihara is a famous song in Bollywood, which refers to this bird and its clarion call. [19]
The long-tailed shrike or rufous-backed shrike is a member of the bird family Laniidae, the shrikes. They are found widely distributed across Asia and there are variations in plumage across the range. The species ranges across much of Asia, both on the mainland and the eastern archipelagos. The eastern or Himalayan subspecies, L. s. tricolor, is sometimes called the black-headed shrike. Although there are considerable differences in plumage among the subspecies, they all have a long and narrow black tail, have a black mask and forehead, rufous rump and flanks and a small white patch on the shoulder. It is considered to form a superspecies with the grey-backed shrike which breeds on the Tibetan Plateau.
The shikra is a small bird of prey in the family Accipitridae found widely distributed in Asia and Africa where it is also called the little banded goshawk. The African forms may represent a separate species but have usually been considered as subspecies of the shikra. The shikra is very similar in appearance, as well as behavior, at least to some degree, to other species including the Chinese sparrowhawk, Eurasian goshawk and Eurasian sparrowhawk. They have a sharp two-note call and exhibit the flap-and-glide flight style typical of Tachyspiza and Accipiter hawks. Their calls are imitated by drongos and the common hawk-cuckoo resembles it in plumage. This species was formerly placed in the genus Accipiter.
The red-faced malkoha is a member of the cuckoo order of birds, the Cuculiformes. This malkoha species is endemic to Sri Lanka
The Asian koel is a member of the cuckoo order of birds, the Cuculiformes. It is found in the Indian Subcontinent, China, and Southeast Asia. It forms a superspecies with the closely related black-billed koels, and Pacific koels which are sometimes treated as subspecies. The Asian koel like many of its related cuckoo kin is a brood parasite that lays its eggs in the nests of crows and other hosts, who raise its young. They are unusual among the cuckoos in being largely frugivorous as adults. The name koel is echoic in origin with several language variants. The bird is a widely used symbol in Indian and Nepali poetry.
The Jacobin cuckoo, also pied cuckoo or pied crested cuckoo, is a member of the cuckoo order of birds that is found in Africa and Asia. It is partially migratory and in India, it has been considered a harbinger of the monsoon rains due to the timing of its arrival. It has been associated with a bird in Indian mythology and poetry, known as the chātaka represented as a bird with a beak on its head that waits for rains to quench its thirst.
The purple-rumped sunbird is a sunbird endemic to the Indian Subcontinent. Like other sunbirds, they are small in size, feeding mainly on nectar but sometimes take insects, particularly when feeding young. They can hover for short durations but usually perch to lap nectar from flowers. They build a hanging pouch nest made up of cobwebs, lichens and plant material. Males are contrastingly coloured but females are olive above and yellow to buff below. Males are easily distinguished from the purple sunbird by the light coloured underside while females can be told apart from males by their whitish throats.
The jungle babbler is a member of the family Leiothrichidae found in the Indian subcontinent. Jungle babblers are gregarious birds that forage in small groups of six to ten birds, a habit that has given them the popular name of "Seven Sisters" in urban Northern India, and in Bengali, with cognates in other regional languages which also mean "seven brothers".
The yellow-billed babbler is a member of the family Leiothrichidae endemic to southern India and Sri Lanka. The yellow-billed babbler is a common resident breeding bird in Sri Lanka and southern India. Its habitat is scrub, cultivation and garden land. This species, like most babblers, is not migratory, and has short rounded wings and a weak flight and is usually seen calling and foraging in groups. It is often mistaken for the jungle babbler, whose range overlaps in parts of southern India, although it has a distinctive call and tends to be found in more vegetated habitats. Its name is also confused with Turdoides leucocephala, which is also known as white-headed babbler.
The black drongo is a small Asian passerine bird of the drongo family Dicruridae. It is a common resident breeder in much of tropical southern Asia from southwest Iran through Pakistan, India, Bangladesh and Sri Lanka east to southern China and Indonesia and accidental visitor of Japan. It is an all black bird with a distinctive forked tail and measures 28 cm (11 in) in length. It feeds on insects, and is common in open agricultural areas and light forest throughout its range, perching conspicuously on a bare perch or along power or telephone lines.
The Indian cuckoo or short-winged cuckoo is a member of the cuckoo order of birds, the Cuculiformes, that is found in the Indian subcontinent and Southeast Asia. It ranges from India, Bangladesh, Bhutan, Nepal and Sri Lanka east to Indonesia and north to China and Russia. It is a solitary and shy bird, found in forests and open woodland at up to 3,600 m (11,800 ft).
The yellow-eyed babbler is a passerine bird native to South and Southeast Asia. It inhabits shrubland, grassland and wetland habitats. On the IUCN Red List, it is listed as Least Concern because of its wide distribution and stable population.
The banded bay cuckoo or bay-banded cuckoo is a species of small cuckoo found in the Indian subcontinent and Southeast Asia. Like others in the genus they have round nostrils. They are usually founded in well-wooded areas mainly in the lower hills. Males sing from exposed branches during the breeding season, which can vary with region. They are distinctive both in their calls as well as plumage with a white eyebrowed appearance and the rufous upperparts with regular dark bands and the whitish underside with fine striations.
The large gray babbler is a member of the family Leiothrichidae found across India and far western Nepal. They are locally common in the scrub, open forest and gardenland. They are usually seen in small groups and are easily distinguished from other babblers in the region by their nasal call and the whitish outer feathers to their long tail. It is one of the largest babblers in the region.
Cuculus is a genus of cuckoos which has representatives in most of the Old World, although the greatest diversity is in tropical southern and southeastern Asia.
The large hawk-cuckoo is a species of cuckoo in the family Cuculidae. It has a wide breeding distribution from temperate Asia along the Himalayas extending to East Asia. Many populations winter further south. They are known for their loud and repetitive calls which are similar to that of the common hawk-cuckoo but do not rise in crescendo. They are also somewhat larger and adults can be readily told apart from the smaller common hawk-cuckoo by the black patch on the chin. They are brood-parasites of babblers and laughing-thrushes.
The fork-tailed drongo-cuckoo is a species of cuckoo that resembles the Black drongo. It is found mainly in hill forests in peninsular India and Sri Lanka although some specimens are known from the Himalayan foothills. It can be identified by its metallic black plumage, straight beak, white barred vent, forked tail and white spot on the back of the head. The fork-tailed drongo-cuckoo's song has been described as a series of 5 or 6 whistling "pip-pip-pip-pip-pip-" notes rising in pitch with each "pip". They are also known for their drongo-like calls such as "quip" calls in flight and "wheep-wheep" call with a higher second note. In Sri Lanka, the fork-tailed drongo-cuckoo also has similar calls to the Sri Lanka Drongo.
